Energy harvesting 

This project aims at development self-powered wireless sensors for a variety of applications. We develop energy harvesters, energy conversion circuitry and ultra-low power sensors. One of the goals is to design a platform that is agnostic to the energy source: vibration energy harvested by an electromagnetic harvester or piezo harvester; wind energy, energy of thermal gradiaents, etc.

Electromagnetic energy harvesting

In collaboration with P. Pillay we develop an electromagnetic energy harvester for vibration energy. Here is a decription of early bridge experiements.

Piezo energy harvesting

Here is a brief description of a self-powered wireless pressure sensor.
