Abstract
       While the Internet of Things (IoT) continues to expand in both number and variety of deployed devices, keeping them powered unobtrusively is largely an unmet need. Practical systems have concentrated on device efficiency, often reducing function and/or performance so that the battery or device replacement cycle can be lengthened. While batteries have remained the primary energy sources due to their energy density, in certain sensing contexts requiring the operation of sensors and sensor systems over a significant period of time, including implantable biomedical electronic devices and tire pressure sensors, battery usage may be both impractical and add extra cost due to the requirements for periodic recharging and/or replacement. In order to address this challenge and extend the operational lifetime of wireless sensors, there has been an emerging research interest to harvest energy from environmental energy. The subject of my PhD and the focus of this presentation are on the designs of energy harvesters and associated power-conditioning circuits to harvest ambient kinetic energy.
