Wake-on Sound Piezoelectric MEMS Microphone

Wake battery-powered devices from sleep at practically zero power.

Wake-on Sound Piezoelectric MEMS Microphone

Battery-powered electronic devices are everywhere. They’re the TV remotes in the living room, the smart speakers in the study and the Internet of Things (IoT) devices all throughout the house. The problem is that consumers still need to activate them using touch. Turning on the TV to watch a favorite Netflix show or initiating Pandora on a battery-powered smart speaker still requires consumers to push a button. This tethered-to-touch experience is about to go the way of analog television.

Vesper’s VM1010, the first wake-on sound MEMS microphone for consumer electronics, will bring voice activation to battery-powered devices of all kinds. Drawing a scant 8 µA of current while in listening mode, Vesper’s newest piezoelectric MEMS microphone — VM1010 — is the only device that uses sound energy itself to wake a system from full power-down.

Vesper MEMS VM1010Even when fully powered-off, batteries in smartphones and smart speakers naturally dissipate 40-80uA, which is far more current than VM1010 needs. This means that there is no difference in battery-life for a system using VM1010 in listening mode and a fully powered-down conventional system.

VM1010 features a programmable voice zone, allowing voice in a 5-foot radius to 20-foot radius-zone to trigger the system and increase to a higher-power mode. When the environment is quiet, the system can enter the low-power “wake-on-sound” mode.


  • Industry’s lowest-power wake-up
  • Programmable voice zone
  • Single-ended analog output
  • Bottom-port
  • Dust-proof piezoelectric MEMS construction


  • Current Consumption: < 10 uA in “wake-on-sound” mode
  • Signal-to-Noise Ratio: 64 dB(A)
  • Small size: 3.76 mm X 2.65 mm X 0.96 mm package

Get the VM1010 Development Platform

Vesper now offers a turnkey development platform that boasts the lowest overall power consumption for far-field always-listening voice interfaces. The development platform is a turnkey solution that integrates VM1010 with DSP Group’s DBMD4, an ultra-low-power, always-on voice and audio processor based on Sensory’s Truly Handsfree™ voice control embedded algorithms. The platform gives developers the ability to initiate voice processing through Sensory’s wake-up word technology, which ensures that only a specific trigger word activates the device.
