Development of a simple fabrication process for a printable piezoelectric energy harvest device

This paper presents a simple printing process to design a novel piezoelectric energy harvest device made from (VDF/TrFE) copolymers. The fabrication process using metal nano-ink and a household printer dramatically reduced the fabrication complexity. Additionally, this process employed low temperatures and thus the structural damage of the polymers resulting from high temperature annealing could be avoided. An electric power of about 0.06 µJ was generated using this device.
