Silicon MEMS Ultrasound: Technology and Applications

October 20 @ 4:00 pm - 5:30 pm

Ultrasound is utilized in diverse industries such as MedTech (e.g. for imaging, therapy, photoacoustic) or measurement and analysis (e.g. flow flow rate measurement, material characterization, non-destructive testing). Conventional piezoelectric transducers have been by far primary technologies in ubiquitous applications of ultrasound. Capacitive micromachined ultrasound transducer (CMUT) is an all-silicon ultrasound technology that emerges as an attractive alternative, and furthermore drives toward new applications. These silicon-based transducers offer not only limitless miniaturization of transducers or their batch production, but also unique advantages such as wide bandwidth (> 100 %), better impedance matching, high temperature tolerance (>200 °C), and no self-heating. This talk aims to provide an overview of the technology, from design to manufacturing, as well as a few demonstrated applications.
