Abstract

It has been shown that the direct piezoelectric effect occurs in low density, extruded polyethylene cable insulators and a piezoelectric d constant typical for such samples has been evaluated. Heat-treatment of the polyethylene, and oil absorption into it, both reduced the level of charge output. A probable mechanism for the piezoelectric effect in these polyethylene samples is given.
