Energy can be reclaimed and stored for later use to recharge a battery or power a device through a process called energy
harvesting. Piezoelectric is being widely investigated for use in harvesting surrounding energy sources such as sun,
wind, tides, indoor lighting, body movement or machine vibration, etc. This paper introduces a wind energy harvesting
device using a Piezo-Composite Generating Element (PCGE). The PCGE is composed of layers of carbon/epoxy, PZT
ceramic, and glass/epoxy cured at an elevated temperature. In the prototype, The PCGE performs as a secondary beam
element. One end of the PCGE is attached on the frame of the device. The fan blade rotates in the direction of the wind and hits the PCGE's tip. When the PCGE is excited, the effects of the beam deformation allow it to generate electric power. In wind tunnel experiments, the PCGE is excited to vibrate at its first natural frequency and generates the power up to 8.5 mW. The prototype can harvest energy in urban regions with minor wind movement.
