Summary

Over the past few years, researchers have been progressively shrinking devices that scavenge power from vibrations and other ambient sources to nanoscale dimensions in an effort to power everything from minuscule sensors inside the body to arrays of self-powered environmental sensors to monitor things such as air quality and stream flows. This miniaturization push has been aided by the steady progress of microelectronics technology, which now turns out sensors and computing devices small enough and frugal enough with their energy needs that many can be powered with just nanowatts to microwatts of power.
