Energy harvesting solutions for self-powered IoT Gonzalo Murillo,

In the near future, a multitude of wireless sensor nodes spread all around our environment and even our body will be continuously receiving and sending information, measuring data and working together to make more complex processes. This disruptive concept is known as Internet of Things (IoT). One of the main difficulties to make this vision real is the way of powering all these tiny devices. As alternative, energy harvesting from ambient sources becomes a tangible possibility thanks to the great reduction in power consumption of current electronic circuits. This work is mainly focused on energy harvesting from ambient vibrations by means of piezoelectric resonant devices. In this field, ENSOECSEL- H2020 project is dealing with this and other approaches (mechanical, thermal and solar harvesting, wireless charging, and flexible batteries) to develop new energy efficient systems for Smart Objects.
