Wake-on-Sound Piezoelectric MEMS Microphone

Battery-powered electronic devices are all around us. Smart speakers in the study, TV remotes in the living room, and the Internet of Things (IoT) devices throughout the house. The problem is that consumers still need to operate them using touch. Initiating Spotify on a battery-powered smart speaker or switching on the TV still needs consumers to walk across a room and press a button. This tethered-to-touch experience is about to go the way of VHS tapes.

The first wake-on sound MEMS microphone for consumer electronics, Vesper’s VM1010, will bring voice activation to battery-powered devices of every type. Drawing a scant 10 µA of current while in listening mode, Vesper’s newest piezoelectric MEMS microphone – VM1010 – is the only device that utilizes sound energy to wake a system from full power-down.

Batteries in smart speakers and smartphones naturally dissipate ~50uA even when completely powered-off, which is far more current than VM1010 needs. This means that there is no difference in battery-life for a system utilizing VM1010 in listening mode and a totally powered-down conventional system.

VM1010 possesses a programmable loudness threshold, permitting voice activation to be customized for the desired distance and level of background noise. In a quiet environment, the system can enter the low-power “wake-on-sound” mode and bring battery drain to a virtual halt.

Robust and Reliable

As the industry’s first piezoelectric MEMS microphone, VM1010 is the most robust and reliable MEMS microphone for consumer products. It is dustproof, waterproof, shockproof and particle-resistant so you can bathe it in dust, immerse it in water, drop it on the ground, or expose it to particulate matter, and it continues to work correctly.
