WebFeb 1, 2024 · In this work we apply a continuous ultrasound wave measurement approach to detect and measure surface film thicknesses on a solid metal. The principle behind this method is to continuously send a repeating chirp ultrasound wave from a transducer located on the back face of a solid. WebMar 31, 2016 · The Chirp ultrasound transducers are smaller and use less power than other options on the market, he says. The early-stage technology is funded through NSF's Small Business Innovation Research program and was featured at the 2016 International Consumer Electronics Show in the Eureka Park marketplace.
