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.
