Outline of Research at the Start

We are concentrated on the development of low cost, light, eco-friendly, flexible energy harvester for the sensors. Energy harvesting is the use of ambient energy already present in the environment, such as wind, heat, and water drop and converting them into usable electrical energy. Devices capable of energy harvesting mean connection to a typical electrical outlet or a typical battery is unnecessary,thereby allowing the devices to require less maintenance and be potentially wireless.Our goal is fabricating the energy harvester which can supply power to the sensors independently.

Outline of Annual Research Achievements

This year, I continued to study the flexible piezoelectric composites for energy-harvesting. Barium titanate (BaTiO3, BTO) and poly (vinylidene fluoride-trifluoroethylene) copolymers (P(VDF-TrFE)) were used to create a functionally graded, flexible piezoelectric material. The new production method increases output voltage during bending by 15 times and increases figure of merit (FoM) by 3.2 times. This study proposes a novel method for utilizing piezoelectric material to extract energy from human motion. I composed an academic paper based on these findings and submit it to a academic journal; the manuscript is currently undergoing review. In addition, I have attended international and domestic conferences and presented the most recent findings of this study to other researchers.
