This foldable keyboard, created by Michigan State University engineer Nelson Sepulveda and his research team, operates by touch; no battery is needed. Sepulveda developed a new way to harvest energy from human motion using a pioneering device called a biocompatible ferroelectret nanogenerator, or FENG.

The day of charging cellphones with finger swipes and powering Bluetooth headsets simply by walking is now much closer. Michigan State University engineering researchers have created a new way to harvest energy from human motion, using a film-like device that actually can be folded to create more power...
