The physics of ultrasound — sound waves with a frequency above the audible range — has been an enduring interest.

Ultrasound — sound waves with a frequency above the audible range — is widely used for medical imaging and surgery, as well as industrial/commercial applications. Read about a history of its development in medicine.
Our passion for ultrasound comes from its rich interaction with the media it travels through, and the ease with which beams of sound can be formed to solve practical problems.
MEMS are inspired by Richard Feynmann’s classic lecture, There’s plenty of room at the bottom. A classic paper on MEMS is Silicon as a mechanical material. MEMS transducers have sparked increasing interest in the past decade as they leverage the massive investments made in the semiconductor industry.
Frequently, ultrasound and MEMS require specialized microelectronics to fully exploit their application potential. We work with a network of partners to provide comprehensive solutions in these areas.
