Pyroelectricity and Induced Pyroelectric Polarization in Leaves of the Palmlike Plant Encephalartos villosus

This is the authors' abstract. We don't add key points for this paper.

Quantitative pyroelectric measurements were made on the leaves of the palmlike plant Encephalartos. A pyroelectric response almost 50 times higher than the normal one could be induced by a small bias electric field, offering a means for highly increasing the efficiency of conversion of thermal to electrical energy. No evidence of ferroelectricity was found.
