Energy harvesting is the conversion of unused kinetic energy (mechanical, pneumatic, hydraulic, thermic or electromagnetic) in the surrounding environment into small amount of exploitable electrical energy. This technology, as a new power source for small electronic systems, is attracting more attention in the recent years. It is a promising energy source for self-sustained electronic devices with sensors without maintenance with wireless communication capabilities.
We are currently running projects about the realization of new nanotechnology based generators. The mechanisms by which the energy is collected are based on effects such as electromagnetism, triboelectricity and piezoelectricity. The challenge of the work will be the conversion of external mechanical stresses (rotation, translation) with very low frequency (0.1 to 1Hz) into rotational energy to deliver enough electrical power supplying a wireless Bluetooth communication unit. The internship student will have the opportunity to create a first proof of concept prototype with possibility of field tests. The applications concern the smart conversion of mechanical stimulations as human motion from walking, vibrations from vehicles or building, waves from oceans.
