Another interesting point is that maximum process temperatures didn't exceed 150°C, meaning these polyCMUTs could be fabricated directly on top of silicon-based electronics such as beam formers and Tx/Rx switches. The researchers anticipate such ultrasound transceivers could be integrated into flexible substrates for conformal and wearable health monitoring systems
"You could miniaturize these transducers and use them to look inside your arteries and veins. You could stick them on your chest and do live continuous monitoring of your heart in your daily life. It opens up so many different possibilities," commented Robert Rohling, professor of electrical and computer engineering at University of British Columbia and co-author of the paper.
