Abstract

We investigate effects of bending stress on piezoelectric properties of polyvinylidene fluoride (PVDF) as a polymer sensor. The sensor was designed and fabricated into a special size and shape so that it can be attached to small insects, such as the American cockroach (Periplaneta Americana) to measure the insects' locomotion. The performance of the sensor is studied using a controlled linear stage to buckle the sensor mimicking the bending of the sensor due to the leg movements of cockroaches. For comparison, a roach robot was used for multi-leg study. Results indicate that buckling motion of the sensor produce an output that is different from regular stretching effect. The sensor-generated charge depends on the localized stress distribution and dipole alignment. This paper discusses the methods of characterization of piezoelectricity useful for insect applications.
