 Abstract
Polyvinylidene fluoride (PVDF) is a popular piezoelectric polymer because of its mechanical properties, high flexibility, thermal stability, chemical resistance, and relatively low cost. These features make PVDF attractive for applications such as electromechanical actuators and energy harvesters, in which physically flexible devices perform energy conversion. This study used PVDF as the sensor element in a piezoelectric rain sensor that was manufactured from electrospun PVDF nanoweb. The reactivity of the rain sensor was investigated by using high speed photography to study the correlation between the sensor angle and raindrop height, raindrop frequency and raindrop weight. The piezoelectric voltage signals produced were found to vary as a function of raindrop form.
