Powering tomorrow's sensor: a review of technologies – part 2

The paper aims to provide a technical review of new and emerging power sources and their application to sensors.

This is the second part of a two‐part paper. Following a brief introduction, recent developments and research into fuel cell, energy harvesting, microgenerator and wireless power transmission technologies are considered.

All of these technologies are the topic of a major research effort and offer prospects to power future generations of sensors. Several pose strong competition to rechargeable batteties.

The paper provides a detailed insight into new and improved sensor power sources.
