    Nowadays, low-power electronic products have been widely advocated in various applications, such as consumer electronics, wearable electronics, automotive electronics, etc. Nevertheless, these applications all share similar demands upon the electronic devices, namely, low power, small form-factor, low cost, high reliability and ultimately even self-powered. As a matter of fact, the total global market potential for self-powered devices in sensing and other applications is indeed very attractive, which is expected to grow from 13.5 million units in 2008 to 164.1 million units in 2013 [Darnell Research, 2007]. The primary objective of this project is to support the local industries to implement self-powered devices to enhance their products’ competitiveness. The platform technologies to be developed in this project include energy harvester design, energy storage circuitry design, and system implementation. Piezoelectric-based materials such as Lead(Pb)-Zirconate-Titanate (PZT) and/or Polyvinylidene Fluoride (PVDF) will be considered in this project to convert mechanical energy (e.g. vibration, deformation, etc.) into electrical energy. Our target is to provide a one-stop platform for our industries to implement production-ready, low-cost and reliable energy harvester systems into their products. This project will use the tire pressure monitoring system (TPMS), energy scavenging floor, and/or sensor-based intelligent insole as the product demonstration vehicles since the market demands and growths of them are well defined.
