Nearly all military operations require remote power. For instance, consider the modern soldier who has been equipped with an increasingly sophisticated array of sensing, communications, and related electronics. While batteries have historically been used to power these electronics, alternative solutions are now required since a significant number of batteries, along with their increased weight, must be carried to meet the power requirements of short-term missions. Scavenging energy from the ambient environment, to either replace or recharge batteries, is one of the most promising strategies for meeting the power requirements while simultaneously reducing the weight load. However, energy harvesting has yet to reach its full potential because the past works have narrowly focused on frequency matching to achieve linear resonance.
