Vesper World’s First Adaptive ZeroPower Listening™  Enabling “Hands Free” in smart home devices

Extends Battery life and reduces energy vampires in your home

BOSTON – (July 28, 2020) – Vesper, world’s first MEMS supplier of the most advanced piezoelectric sensors, today introduced VM3011 the first intelligent digital microphone with Adaptive ZeroPower Listening™, a disruptive power saving architecture that enables a 10 x extension of battery standby life with best in class acoustic performance. The VM3011 further extends Vesper’s technology leadership in the low power always listening device market.

The VM3011 expands the successful family of products based on Vesper’s patented piezoelectric MEMS transducer technology which leads the industry for quality and performance.  The Adaptive ZeroPower Listening™ technology will automatically learn the acoustic characteristics of the environment in real time allowing the system to ignore background noise and only wake in response to key words or other desired acoustic triggers. This allows the system to hibernate over 90% of the time and extend battery life >10X.

“Existing always listening systems run continuously and must be plugged into an electrical outlet. The VM3011 creates a new paradigm where these systems can now run for months or years on battery power” said Matt Crowley, CEO of Vesper. “This technology will power a new class of products such as always listening far field TV remotes, always listening smartwatches, home security cameras and doorbells with extended battery life and many other systems. Vesper has already engaged with lead customers who plan to roll out products with the VM3011 later this year.”

Target applications for the VM3011 include IoT products, portable smart speakers, smartwatches, far field remote controls, security cameras, glass break sensors, automotive, medical devices and other battery powered systems.

The VM3011 has a native IP57 rating and can operate in harsh environments. It does not require a protective mesh which reduces cost and improves system SNR. Due to our unique piezoelectric MEMS, Vesper is the only company that supplies microphones that remain in spec after being submerged in water or exposed to high levels of particles. This product is ideal for any system placed outdoors or in other environments where the system will be exposed to moisture, liquids, dust or particles.

For More Information

The VM3011 has a small industry standard 3.76 mm X 2.95 mm X 1.3 mm package. It is reflow solder compatible with no sensitivity degradation.  The VM3011 will be available in volume production by Q4 2020. For more information, please email:
