A new technology that can generate electricity from vibrations or even small body movements means you could charge your laptop by typing or power your smartphone’s battery on your morning run.

Researchers at the University of Waterloo have developed a tiny, wearable generator in response to the urgent need for sustainable, clean energy. It is also scalable for larger machines.

“This is a real game changer,” said Dr. Asif Khan, the project’s lead researcher and a postdoctoral fellow in the Department of Electrical and Computer Engineering at Waterloo. “We have made the first device of its kind that can power electronics at low cost and with unprecedented efficiency."

The device uses the piezoelectric effect, which generates electrical energy by applying pressure to materials like crystal and certain ceramics. Piezoelectric materials are currently used in various sensing technologies including sonar, ultrasonic imaging and microwave devices.

The new generator contains materials that are flexible, energy-efficient and relatively less expensive. (University of Waterloo)
