Tiny Generator Powered by Mini Vibrations

Scientists from the University of Southampton have created a tiny generator that converts tiny vibrations from the world around it to make magnets on a cantilever at the heart of the device wobble to generate power.

Creating just microwatts of power, the device is expected to be used to power wireless sensors on equipment in manufacturing plants, but could also be used for medical applications such as powering pacemakers.
