Abstract
Description
Technical Field
The invention relates to electronic equipment, in particular to an electronic patch which can be attached to the skin of a human body or the surface of an object.
Background
The wearable patch or tag may communicate with smartphones and other devices using WiFi, bluetooth, or NFC technology.
Near Field Communication (NFC) is a wireless communication standard that enables two devices within a short distance to establish a communication channel through radio waves in the frequency range of 13.56MHz in a short time. NFC is a very effective technique for transferring data between two devices within a short distance. This technology is more secure than other wireless technologies such as bluetooth, Wi-Fi, etc., since it requires two devices to be close to each other (within 10 centimeters). NFC can therefore be seen as a simple and secure tool to establish a bidirectional fast connection for data transfer. One of the two NFC devices may be a passive NFC patch, using passive energy harvested from the active electromagnetic coupling of the reader, thereby bringing the further benefit of not requiring the use of batteries in the system, simplifying the product design and making it possible to use it as a disposable product.
Where long-range communication is required, such as over 10 meters, and there is no need to touch the NFC patch reader at close range from time to time, data can be automatically and continuously collected with minimal operator intervention. In this case, bluetooth and WiFi are more preferred and are equipped with 1.5 volt or 3 volt batteries.
A wearable tag (or patch) is an electronic tag that can be worn by a user. The wearable patch is required to be capable of being directly attached to the skin of a user, and the function lasts for several hours to several months. The wearable patch may contain a microelectronic system, accessible using NFC, bluetooth, WiFi, or other wireless technology. For example, an authentication wearable patch may be used to identify a user's smartphone for authentication purposes. It can also be combined with different sensors for other purposes such as vital signal monitoring, heartbeat, motion tracking, blood pressure, temperature measurement and electrocardiogram detection.
Despite the extensive development work done in the early days, conventional wearable devices still face several major drawbacks: may not provide sufficient comfort to the wearer; the time length of the adhesive tape adhered to the body of the user can not reach the specified time; and are generally aesthetically undesirable. Another disadvantage of conventional wearable patches is that the rigid polymer substrate provides poor breathability to the skin. The accumulation of sweat moisture can cause skin discomfort and irritation, especially after a period of wear. In addition, the rigid substrate is difficult to conform closely to the curved surface, and therefore some critical biological information needs to be collected by direct contact with the skin without leaving an air gap. For example, an electrocardiogram (commonly referred to as an ECG) can capture and convert the electrical impulses generated by the polarization and depolarization of cardiac tissue into waveforms. These signals need to be picked up by electrodes attached directly to the skin surface and recorded and displayed by an external device. The air gap between the electrode and the skin surface can lead to measurement inaccuracies. In addition, conventional wearable devices are often not sufficiently tough to sustain repeated stretching of the wearable patch as it moves with the body area to which the patch is attached. The layers inside the wearable patch may crack and delaminate under pressure, rendering the patch unusable.
A wearable tag is a particular type of electronic patch. More generally, the electronic patch can be attached to not only a human body but also other objects, such as computers, mobile phones, clothes, packaging materials, shipping boxes and other goods. The electronic patch may communicate wirelessly with a cell phone or other device via NFC, bluetooth, WiFi, or other means.
The electronic patch may be used to track an object by performing sound, light, or vibration generating functions. As various applications and human needs become increasingly complex, the number of functional tasks required to be performed by electronic patches is rapidly increasing.
There is therefore a need for a comfortable and economical electronic patch that can measure different signals, or perform different driving functions.

Detailed Description
The present invention is intended to provide an electronic patch having a wide range of sensing and/or driving functions. Theelectronic patch 100 shown in fig. 1 can be placed on theskin surface 110 of a human body and attached to the skin, such as the forehead, hands, wrists, arms, shoulders, chest, waist, legs, and feet. Flexibleelectronic patch 100 may be used to measure signals such as body temperature, heart beat, blood pressure, electrocardiogram signals, motion signals, or perform sound, light, or vibration generating functions.Electronic patch 100 may also be used for attachment to an object surface for tracking, measuring, or generating signals.
Referring to fig. 2A-2C, theelectronic patch assembly 200 includes a mainelectronic patch 210 including a plurality of conductive connection points 215,216, 217 on an upper surface of the mainelectronic patch 210. The conductive connection points 215, 216, 217 may be arranged in groups, as shown below, configured for connection with different electronic patches. The conductive connection points 215, 216, 217 may be formed from a matrix of resilient or elastomeric material, such as silicone or polyurethane, embedded with a conductive material, such as silver particles or silver flakes. The connection points may also be made of conductive mechanical parts as described above.
The mainelectronic patch 210 may include acircuit 211,electronic components 212, and a semiconductor chip (or chips) 213 to provide one or more functions. The lower surface of the mainelectronic patch 210 may be applied with an adhesive so that it can be attached to the skin of a human or the surface of an object.
Theelectronic patch assembly 200 may also include a modularelectronic patch 230 on theadhesive layer 220 stacked on the mainelectronic patch 210. The modularelectronic patch 230 may include acircuit 231, asemiconductor chip 233, and other electronic components. Theadhesive layer 220 includes a plurality ofwindows adhesive layer 220 may be a pressure sensitive adhesive or a repositionable adhesive that can be easily removed without damaging the primary electronic patch. The modularelectronic patch 230 has conductive connection points 235 on its lower surface. Theconnection point 235 is adapted to contact theconnection point 215 on the mainelectronic patch 210 through thewindow 225 on theadhesive layer 220. The modularelectronic patch 230 may includewindows windows adhesive layer 220, expose the connection points 216, 217, respectively, on the primaryelectronic patch 210.
The electronic communication between the modularelectronic patch 230 and the mainelectronic patch 210 enables them to share communication and control functions in theelectronic patch combination 200. For example, if the masterelectronic patch 210 includes functionality to wirelessly communicate with an external device, control and measurement information related to the modularelectronic patch 230 may be communicated to the external device through the masterelectronic patch 210. The functionality of the mainelectronic patch 210 may be flexibly expanded by electrical connection to one or more modular electronic patches. The primaryelectronic patch 210 serves as a system frame to which a set of modular component patches, such as 230, are attached. The functionality of the entireelectronic patch 200 may be specifically tailored by integrating a single or multiple modularelectronic patches 230.
In some examples, theelectronic patch assembly 200 may include some sort of "local intelligence" that enables the modularelectronic patch 230 and the masterelectronic patch 210 to dynamically alter how each function is performed. In other words, the sensor and/or driver on one of theelectronic patches electronic patches electronic patch 210 may measure the electrical activity of the body's organs such as electrocardiogram, electroencephalogram, electromyogram, while the modularelectronic patch 230 may measure the heartbeat or/and produce light or sound signals. The masterelectronic patch 210 may have such logic and intelligence pre-stored or programmed to send control signals to the modularelectronic patch 230 in response to electrical signals measured from the human body. One application of this approach is that an electrocardiogram and heart beat can be measured simultaneously, providing confirmation for analysis. For example, in one application, when an abnormal electrocardiogram signal is detected, the mainelectronic patch 210 may send a control signal to the modularelectronic patch 230 causing it to send an optical or acoustic alarm signal.
In another example, the modularelectronic patch 230 may include a temperature sensor that outputs an electrical signal indicative of the measured ambient temperature, while the bottom primaryelectronic patch 210 measures the body surface temperature by directly contacting the skin surface. The ambient temperature electrical signal read by the modularelectronic patch 230 is transmitted to the hostelectronic patch 210 through the connection points 236 and 215 that are in contact with each other. The ambient temperature reading taken by the modularelectronic patch 230 can be used as an important indicator of the body surface temperature reading taken from the bottom mainelectronic patch 210. This can be used in situations where accurate measurement of body temperature is required, such as measuring the temperature cycle of a female to predict the best time to prepare for pregnancy.
The primaryelectronic patch 210 and the modularelectronic patch 230 may each include one or more layers. For example, one or more elastomeric layers and a support substrate may be included. The elastic layer may be comprised of a viscoelastic polymer having a low young's modulus and a high strain-to-failure. In some examples, the elastic layer may have a young's modulus of less than 0.3 Gpa. In some cases, the elastic layer may have a Young's modulus of less than 0.1GPa to enhance flexibility and adhesion. Suitable materials forelastic layer 210 include elastomers and viscoelastic polymers such as silicone and medical polyurethane, which is a transparent medical dressing for covering and protecting wounds, is breathable, and is conformable to the skin. On the other hand, the support substrate has sufficient rigidity to support thecircuit 211, such as an antenna circuit, and theelectronic components 212, such as resistors, capacitors, sensors, drivers, chemical delivery devices, and the like, and thesemiconductor chip 213. Other electronic components may include capacitors, transformers, resistors, metal pads, diodes, transistors, and amplifiers. In some examples, the support substrate may have a Young's modulus greater than 0.5GPa, such as between 1.0 and 10 GPa. Suitable materials for the substrate are, for example, polyimides, polyesters, aramids, composites, glass epoxy resins and polyethylene naphthalate. Importantly, the support substrate structure is designed to provide extensibility to the primary and modular electronic patches. The support substrate may include one or more openings that allow the electronic patch to shear and stretch when stretched or elongated. By selectively forming openings in the support substrate, the effective flexibility of the support substrate can be made substantially higher than the inherent elasticity of the support substrate material (lowering the effective elastic constant).
Multilayer wearable labels or patch sheets having stretch and shear properties as details of a particular illustration of the electronic patch of the present invention are set forth in co-assigned pending U.S. patent application 14/454, 457 entitled "extensible multilayer wearable label capable of wireless communication," filed on 8/7/2014; it is stated in U.S. patent application 14/491, 665 entitled "highly flexible wearable wireless patch with stress relief", filed 9/19/2014; also set forth in U.S. patent application 14/520, 674, entitled "Flexible wearable Patch sheet capable of measuring electronic signals", filed 10/2014. The contents of the patent application specifications for these applications are incorporated herein by reference.
In some examples, three electronic patches may be stacked on top of each other to achieve a wider range of functionality. According to fig. 3A-3C, theelectronic patch assembly 300 includes a mainelectronic patch 210 and two modularelectronic patches electronic patch assembly 200 described above, the mainelectronic patch 210 and the modularelectronic patch 230 are stacked on top of each other with theadhesive layer 220 therebetween.
The mainelectronic patch 210 may include an adhesive layer on the lower surface. The adhesive layer may be a pressure sensitive material such that the mainelectronic patch 210 is tightly attached to the skin under pressure, for example, by pressing with a thumb. For example, the adhesive layer may be made of a medical pressure sensitive adhesive. An example of a material that can be used for such an adhesive is a medical grade pre-set hypoallergenic pressure sensitive adhesive.
The mainelectronic patch 210 may include a circuit, such as an antenna circuit, electronic components, and a semiconductor chip (or chips) to perform one or more functions, but are not shown for clarity. The mainelectronic patch 210 may have an adhesive applied to its lower surface to allow it to be attached to the skin or object of a person. The primaryelectronic patch 210 and the modularelectronic patch 230 may be in electronic communication with each other through aconductive connection 215 and aconductive connection 235, which are in contact with each other through awindow 225 in the adhesive layer.
As described above, thewindows adhesive layer 220 and thewindows electronic patch 230 connect the conductive connection points 216, 217 to the second modularelectronic patch 250. Theelectronic patch assembly 200 further includes anadhesive layer 240 disposed on the lower surface of the modularelectronic patch 250. Theadhesive layer 240 includes a plurality ofwindows
Modularelectronic patch 250 is disposed onadhesive layer 240. The modularelectronic patch 250 includes conductive connection points 256 on its lower surface for contacting the conductive connection points 216 on the mainelectronic patch 210 through the windows 226,236, 246 in the adhesive layer and modularelectronic patch 230. The modularelectronic patch 250 may includewindows connection points electronic patch 230 and the mainelectronic patch 210.

In some examples, the configuration of at least one of the mainelectronic patch 210 and the modularelectronic patches electronic patch 210 and/or the two modularelectronic patches
Details of wireless communication between a multi-layer wearable tag or patch having extensibility and cuttability and an external device are set forth in co-assigned pending U.S. patent application 14/454, 457 entitled "extensible multi-layer wearable tag capable of wireless communication," filed on 8/7/2014; stated in U.S. patent application No. 14/491, 665 entitled "highly flexible wearable wireless patch with stress relief", filed 9/19/2014; also set forth in U.S. patent application 14/520, 674, entitled "Flexible wearable Patch sheet capable of measuring electronic signals", filed 10/2014. The patent application specifications for these applications are compatible with the electronic patches described in this patent application, the contents of which are incorporated herein by reference.
For example, the mainelectronic patch 210 may include necessary semiconductor chips, circuitry, and optionally an antenna circuit for wireless communication. In one application, the mainelectronic patch 210 may also include an electrode layer configured to contact the skin of a user to measure electrical activity of a body organ, such as electrocardiogram, electroencephalogram, electromyogram, and the like. The mainelectronic patch 210 may transmit such electrical signals to an external device. Details regarding multilayer wearable tags or patches capable of measuring electrical signals from the human body and compatible with the electronic patches described herein are set forth in commonly assigned pending U.S. patent application 14/520, 674, entitled "Flexible wearable patch capable of measuring electrical signals", filed on month 10, 22, 2014. The contents of which are incorporated herein by reference.
In another example, the modularelectronic patch 250 may include a device, such as a sensor, configured to measure a user's heartbeat. The electrical signal output of the sensor is transmitted to the mainelectronic patch 210 via the connection points 256 and 216, which are in contact with each other, and in turn transmitted to an external device via wireless. Similarly, additional modular electronic patches may also be added to the electronic patch combination to achieve additional functionality.
In some examples, the modular electronic patch may be a disposable component, while the main electronic patch may be used for a long period of time. The main electronic patch may include more complex and expensive components to perform functions such as wireless communication and some actuation functions. When different applications need to be realized, the modular electronic patch can be replaced.
In some examples, a modular electronic patch may be a battery module that supplies power to the main electronic patch and other modular electronic patches. After the power in the battery is exhausted, the module electronic patch can be removed and independently charged through the charging equipment; it can be replaced with a new battery module.
In some examples, the primary electronic patch may perform primarily a bonding function. The main electronic patch can have an adhesive function on both sides, so that the patch can be attached to the skin of a user and other module electronic patches. After a period of use, if the function is temporarily not needed, the electronic patch assembly can be removed from the user's skin; the master patch may be discarded. The other modular electronic patches stacked on top can be stored for later reuse. If the master patch becomes dirty or loses its adhesive ability, it can be replaced with a new master patch for continued wearing and measurement for a period of time. Thus, the modular electronic patch can be used for days and weeks without losing the adhesive capacity to the skin and without consuming more patches.
