The new device can be used in a variety of applications, ranging from wireless sensor units to patches that get energy from vibrations and pass it on to the grid. The sample they tested got as much as 3.7 mW.

The process harvests small amounts of waste energy in the form of stray vibrations and noise from the environment to break the chemical bonds in water and generate hydrogen and oxygen.
