HYBRID PHOTOVOLTAIC AND PIEZOELECTRIC FIBER

摘要

The invention provides hybrid photovoltaic-piezoelectric energy harvesting devices in the form of flexible filaments. The devices harvest energy from ambient light, and also from environmental motions and vibrations. They are particularly suitable for incorporation into fabrics and clothing.
