In the recent years the semiconductor industry has made amazing progresses in delivering higher performance at lower power consumption. However, the gap between the energy need and availability not only persists, but is continuously widening. One way to address this dilemma is to design bigger or denser batteries for the phones, impacting cost or weight or both, but this is not enough to effectively close the energy gap. A smarter way is to multiply the sources of available energy and recharge t
