Whether it’s the AA batteries that go in TV remotes or the lithium-ion batteries found in smartphones, you probably have a pretty definite image that springs to mind when someone mentions “battery.” That could soon change, however, based on research coming out of the Binghamton University in New York, where scientists have developed a stretchy, textile-based, bacteria-powered bio-battery that could one day be used to power wearable devices. In demonstrations, the battery was shown to be able to exhibit stable electricity-generating capabilities even after repeated stretching and twisting cycles.

Ultrathin zinc-polymer battery.

Imprint Energy is developing flexible, rechargeable batteries that can be printed cheaply on commonly used industrial screen printers. The California startup has been testing its ultrathin zinc-polymer batteries in wrist-worn devices and hopes to sell them to manufacturers of wearable electronics, medical devices, smart labels, and environmental sensors.
