The capacitive microphone is attached to the skin artery to sense the arterial velocity pulse wave. According to the principle of the capacitive accelerometer based on the change in the capacitance pole distance, the capacitance value changes when the movable diaphragm is subjected to an external force shock wave (d). C = ε * S / d (ε = dielectric constant, S = electrode plate area, d = gap between two electrode plates), the change in capacitance value corresponds to the value of acceleration. The condenser microphone and condenser accelerometer have the same operating principle. Became a vibration capacitive accelerometer, and the acceleration pulse wave is converted to resist the environmental noise interference. In addition, condenser microphones can also be used in smart phones, smart bracelets, ear-hook detection devices, headset smart glasses, and more. When a capacitive accelerometer is applied to a smart phone, the smart phone has a jack. For example, the jack can be a headphone jack, a USB jack, a micro USB jack, a type-C jack, or a charging jack. Capacitive accelerometer modules are plugged into the jacks of smart phones. Each capacitive accelerometer is used to sense and identify the user's arterial acceleration pulse wave through the built-in program of the smart phone in a contact manner. In addition, the capacitive accelerometer module can be built in the mobile phone device, and the capacitive accelerometer module can also be externally connected to the mobile phone device.
在一實施例中，電容式麥克風用於感測動脈速度脈波並轉換為加速度脈波，加速度脈波包括一基線與六個極值。六個極值相對基線的偏離用以反應血管生理狀態。當餐後血糖升高時促使血液黏度增加和血液黏度係數上升，根據泊肅葉定律(Poiseuille's law)，血流阻力R=(8η△χ)/(πr4)，(η=血液黏度係數，△χ=血管單位長度，π=圓周率，r=血管半徑)，血管中血液流動阻力與血液黏度係數成正比，促使血流速度下降。動脈加速度脈波的六個極值隨血糖波動而變動。In one embodiment, the condenser microphone is used for sensing an arterial velocity pulse wave and converting it into an acceleration pulse wave. The acceleration pulse wave includes a baseline and six extreme values. The deviation of the six extreme values from the baseline is used to reflect the physiological state of the blood vessels. When postprandial blood glucose rises, blood viscosity increases and blood viscosity coefficient increases. According to Poiseuille's law, blood flow resistance R = (8η △ χ) / (πr4 ), (η = blood viscosity coefficient △ χ = length of blood vessel unit, π = circumference ratio, r = blood vessel radius), the resistance of blood flow in the blood vessel is proportional to the blood viscosity coefficient, and the blood flow speed is reduced. The six extreme values of the arterial acceleration pulse wave change with the fluctuation of blood glucose.

First, the fasting pulse wave before the meal is measured as the basal acceleration pulse wave of the user or the fasting blood glucose level before the meal. Next, the pulse wave 1 hour after the meal is measured as the acceleration pulse 1 hour after the meal or the blood glucose 1 hour after the meal.Next, two hours after meals and three hours after meals were measured to measure the acceleration pulses of individual ground meals two hours and three hours after meals. Compare the six extreme values of the acceleration pulse wave before and after meals, 1 hour after meals, 2 hours after meals, and 3 hours after meals, and the baseline deviation and recovery. Normally, the extreme value of the acceleration pulse 3 hours after a meal will be similar to the extreme value of the acceleration pulse before a meal as a normal person's blood glucose fluctuation.
