Metal Layer reinforced multilayer ferroelectret-based energy harvester

Abstract

This paper presents a flexible insole energy harvester made from multiple layers of ferroelectret polymer foams and nickel metal films. The ferroelectret stack has been fabricated by distributing a number of layers of nickel film through the ferroelectret. The addition of the thin metal films has improved the mechanical coupling to the ferroelectret foams within the stack and enhanced its voltage and energy output.
