In the process of clinical treatment, there are many methods for the fixation of fractures. The steel plate is fixed on the bone by screws, so that the steel plate and the bone are integrated.

The speed of transformation is slow, which limits its application. Therefore, designing a steel plate that can adjust the stress at the fracture end and promote fracture healing is an urgent clinical problem to be solved.
