Vesper MEMS Microphones Save Energy, Last Longer

Vesper MEMS Microphones Save Energy, Last Longer
Apr-01-17
Tiny microphones able to harvest energy from sound could lead to more robust and longer lasting voice-enabled devices.

Developed by a team from the startup Vesper, the MEMS microphone design replaces the rather vulnerable and energy-hungry diaphragm with a layer of flexible cantilevers. Sound waves entering the Vesper microphone will cause the cantilever to bend, generating an electric signal that translates into sound.That sound energy is also used to turn on the microphone, eliminating the need to push a button or have the device in energy-consuming always-on mode.
