Abstract

Energy harvesting, the process of collecting low level ambient energy and converting it into electrical energy, is a promising approach to power wearable devices. By converting the energy of the human body by using piezoelectric and thermoelectric principles, the need for batteries and charging can be avoided, and the autonomy of wearable devices can be significantly increased. Due to the inherent random nature of human motion, however, the energy harvesting devices need to be specifically designed in order to ensure their optimal operation and sufficient power generation. Using several combined approaches, a new class of autonomous devices, suitable for telemedicine, patient monitoring or IoT applications, can be developed.
