A Human Body Power Transfer System to Enable Battery-Less Sensor Nodes

What is it about?

New wearable technologies come with high requirements for miniaturization and flexibility, which are usually restricted by rigid batteries. Capacitive power transfer and communication, employing the human body as a conductive medium enables energy-efficient communication and even the possibility to achieve battery-less wearable sensors distributed on the body.

Why is it important?

Human-centered wearable applications in the Internet of Things increasingly gain popularity such as fitness trackers or dietary monitoring. The main drawback of commercial and academic wearable devices is the need to periodically recharge their batteries which can reduce the appeal of wearables. In fact, the limited energy availability on such devices reduces the long-term reliability of such IoT nodes.
