Using 3D-printing, we design advanced materials that manipulate sound waves in ways not possible with natural materials. These metamaterials efficiently focus acoustic energy, improving power harvesting and high-resolution imaging in water, air, and solids. Our work enables more efficient energy transfer, enhanced acoustic sensing, and new capabilities in ultrasound-based diagnostics.

We use ultrasound to wirelessly power and communicate with battery-free sensors in challenging environments such as the ocean, nuclear waste containers, and space. We aim to scale this technology for widespread environmental monitoring, enabling real-time insights into underwater circulation, water quality, and infrastructure health.

We cross disciplines to build ultrasonic systems that push ultrasound imaging resolution, make it accessible, and enable new applications. For example, our contactless ultrasonic NDT technology ensures the rapid, safe production of critical aircraft parts using additive manufacturing techniques.
