Abstract
The inverse piezoelectric effect has previously been reported in polymers such as PVC and PMMA [1] and even such amorphous materials as wood and bone [2]. The following work has confirmed that PVC will show the effect, as will polyethylene. A direction of anisotropy was introduced into the samples by a polarising voltage, and results for the value of the piezoelectric g constant against the polarising field are given for a sample of polyethylene.
