SENSOR CAPABLE OF SENSING PRESSURE BY MEANS OF DEFORMATION OF A WRINKLED PIEZOELECTRIC LAYER

摘要

The invention relates to a sensor that is sensitive to pressure, including a substrate (1) that supports a piezoelectric layer (2) made of a piezoelectric material, characterized in that the piezoelectric layer (2) has surface waves in the form of wrinkles, onto which pressure is exerted when the sensor is used. The piezoelectric layer is sandwiched between two electrodes (3a, 4) in order to enable charges generated by the deformation of the piezoelectric layer to be collected.
