Energy harvesting

Smart Cities, Smart Grids, and in general, all M2M applications demand very high energy-efficiency. Once deployed, an M2M network must live for years of even decades. Therefore, energy-efficiency is a common concern in all designs conducted at the M2M Department of CTTC.

In addition, the capability of capturing energy from the environment has received lots of attention in the last years. There are several potential energy sources such as solar, mechanical vibration, thermal and even electromagnetic. The best option is studied on a case by case basis, since it depends on application and particular environment.

The main activities of the M2M Department of CTTC are not to design energy harvesters, but on the use of these harvesting-capable devices to design communication protocols, and ultimately, to design ever-lasting M2M applications with zero-power operation.
