At the Metasonics Lab, we use sound to sense the world in new ways

Acoustics for the Internet-of-Things

We use ultrasound to power & communicate with battery-free sensors in challenging environments. For example, our underwater sensors can operate with the tiny power harvested from sound. Our sensors also use sound to wirelessly transmit their readings eliminating the need for any batteries. Our vision is to deploy these sensors at scale in rivers and oceans to monitor underwater circulation and water quality.

Acoustic Metamaterials

We translate cutting-edge theoretical concepts in physics and material science into practical solutions. Using 3D-printing, we created new materials and structures that guide sound in new ways beyond natural materials. Our materials can guide acoustic & ultrasonic waves underwater and in-air to make them more directional and focus their power at smaller spots for harvesting energy efficiently.

Ultrasonic Imaging

We love crossing disciplines to build systems that solve real-world problems. We build systems and develop algorithms to push the imaging resolution of ultrasound and enable new applications. Our most recent technology captures microscale defects in additively manufactured aerospace components of different shapes and sizes. Using our technology, aerospace manufacturers will soon build critical aircraft parts rapidly using additive manufacturing without sacrificing safety.

IoT Transducers

We model, design, and build acoustic transducers (ultrasonic probes, hydrophones, communication transducers) to generate and capture ultrasonic waves in multiple domains (water/tissue/metals/air). We tailor them for new applications including smart health, ocean IoT, and imaging 3D-printed metals.
