Micro-devices and nanostructured materials for energy harvesting

The sensor’s power autonomy is still the bottleneck in Wireless Sensors Networks. Getting electrical energy from ambient sources is a solution to increase the lifetime or even to replace batteries, but it becomes very challenging when addressing miniature transducers.

Our research deals with innovative solutions able to improve the efficiency of small silicon-based energy transducers that collect energy from vibrations, light or temperature gradients. Examples of current hot topics are nonlinear MEMS vibration energy harvesters, nanostructured silicon for solar cells or for efficient thermoelectric meta-materials. We also develop physical models to optimize bottom-up nanostructured materials.
