Evaluating the Shape of a Deformed PVDF Wearable Pressure Sensors by Analyzing an Acoustic Traveling Wave
摘要
The effect of the change in geometry of a strip due to rolling, folding, and stretching during its performance is discussed in this paper. The form of a flexible piezoelectric strip can considerably affect the time of flight (ToF) of an acoustic wave traveling alongside a strip. Different ToFs can follow the effect of curvature in the flexible strips, which can predict the geometrical shape of the strips performing as a flexible actuator or sensor.
