Vesper Technologies, Inc.

Vesper offers the first MEMS microphones that withstand real-world use in smartphones and other connected devices. Vesper’s are the only MEMS microphones rugged enough to withstand water, dust and particle contaminants. They’re high-performance and enable acoustically rich experiences for any application – from smartphones and wearables to Internet of Things (IoT) devices and connected automobiles.

What We Do

Technology changes, but the natural human preference for communicating by voice is constant. As the number of electronic devices in our world grows, our need for natural communication is even greater. And whether we are communicating with people or machines, the quality and reliability of the voice interface becomes increasingly critical. Microphones are the gateway between the digital world and the natural world of human voice.

Vesper’s mission is to dramatically improve the reliability of the voice user interface for smartphones, smart speakers, connected automobiles and any connected device using our proprietary piezoelectric MEMS technology invented by our founders at the University of Michigan.

The Piezoelectric Difference

Vesper piezoelectric microphones operate on a completely different physical principle from all other MEMS and electret condenser-style audio devices. Using the piezoelectric effect, first discovered by Jacques and Pierre Curie, Vesper’s MEMS microphones directly convert sound wave energy into an electrical signal.

Beyond just delivering an excellent signal-to-noise ratio (SNR), Vesper microphones are stably matched, making them uniquely suited for large array applications in smartphones, tablets, smart home devices and other connected products. Vesper’s are the most durable, waterproof, shockproof, and both dust- and particle-resistant microphones on the market.
