Armchair comment. I would LOVE to be a grad student again and try to pair it with ultrasound speaker arrays, for medical applications. Essentially a super HIFU (High-Intensity Focused Ultrasound) with live feedback. https://en.wikipedia.org/wiki/Focused_ultrasound

I do my PhD in in-air ultrasound with phased arrays and talk to the medical guys at conferences/labs that we talk to and it's soooo much harder in solids/liquids. The frequency is significantly higher, think 1-10MHz instead of like 40khz, so any normal electronics are out the window.

Then, why not be a grad student again?

Maybe they want to afford dinner?

Hey saw your message a while back in a thread talking about continuous glucose meters and feeling tired and fatigued etc. Mind contacting me? I'd love to chat. My email is in my profile

TANSTAAFL, but student loans too.

One problem is that the speed of sound is not constant (or approximately constant) across the bandwidth you're interested in when the sound wave is traveling through solids and liquids.

I may be the FUS grad student you seek. Reach out via profile email if you want to chat. Cheers!

Medical applications would presumably require contact coupling and not through air?
