Abstract:

The reality of the ‘Internet of Things (IoT)’ and machine to machine (M2M) communications and associated technologies are pushing the limit not only for personal computers and mobile phones but also for the billions of so-called “things” and devices which are going to have wireless interconnection through the Internet or local area networks. With those billions of things/sensors comes a major challenge – that is how to power them. The concept of having billions of batteries deployed with these sensors will fail due to the cost of replacement and ultimate safe disposal.

MEMS energy harvesting from ambience particularly from mechanical vibrations available everywhere in our daily life presents a straightforward solution for easily powering these remote/ubiquitous devices using clean energy sources. In the present talk Prof Roy, Tyndall National Institute, Ireland will outline their recent works on how magnetic microsystems/nanomagnetics can enable power generation and efficient conversion, powering tiny autonomous sensor nodes leading to the realization of IoT.
