Vesper’s always-listening piezoelectric MEMS microphones let battery-powered devices stay in wake-on-sound mode without draining the battery. They are also waterproof, dustproof and particle-resist...

Vesper’s new Wake on Sound development board – which features Vesper’s VM1010 piezoelectric MEMS microphone with ZeroPower Listening, DSP Group’s DBMD6 DSP, and Sensory’s keyword-detection algorith...

At Vesper, we built a handler to test thousands of microphones at once. Our microphones arrive in trays, which are fed into our fully-automatic handler. Each microphone is individually tested in a ...

BioMimetic Systems is a company which builds gunshot detection systems. They use microphone arrays to locate enemy fire and protect soldiers. These ultra-robust microphones cost hundreds of dollars...

Vesper's VM1000 piezoelectric microphone is incredibly tough and water-resistant, so we put it through the ultimate test - recording whales in the Boston Harbor. We got on the deck of a whale-watch...

Vesper’s piezoelectric MEMS microphone is fully operational when immersed in water. In fact, it can even work like a hydrophone so it can capture sounds that are otherwise impossible to record. Ves...

Vesper’s quiescent sensing microphone is a pencil-point sized piezoelectric MEMS device that can activate idle electronics while drawing almost zero power in standby mode – using just voice input.

Here’s how Vesper’s microphone works.
