MEMS Mic Saves Battery Juice In Voice-activated Systems

Vesper’s VM1010 makes the lofty claim of being the first MEMS microphone to draw nearly zero power in consumer-based voice activation designs. The component is a tiny, ultra-rugged piezoelectric MEMS microphone that allows product designers to offer touchless user interfaces to consumers. Consuming 6 µA while in listening mode, the VM1010 extends battery life to months or years by enabling the rest of the system to completely power down while waiting for a keyword.

 

VM1010 is a low-noise, high dynamic range, single-ended analog output piezoelectric MEMS microphone. It features a configurable voice zone, allowing voice in a 5-ft. radius to 20-ft. radius-zone to trigger the system and increase to a normal operation mode. When the environment is quiet, the system can enter ZeroPower Listening mode and the entire system can power down.

 

Additionally, the VM1010 is dustproof to IP5X and waterproof to IPX7. It is currently sampling and is available online through Digi-Key. For more info, go to http://www.vespermems.com.
