Has the thought even entered you mind that the anon could possibly have already been down that path and has been blocked? A better response than trying to be cute would have been to ask that question!
I don't feel it necessary to question anon's reason for asking though.
It's ultrasonic therefore must have skin contact to function.
I'd be really interested to read the document that you found that information on. I've been looking for something like that since May and I haven't had any success. This ultrasonic one is the closest but it requires skin contact. if it could be something like the RFID system where it's passively powered by an external stimulation, similar to the ultrasonic chip, it would be what I'm looking for. I have some project thoughts in mind but it needs tech that simply isn't available. so I guess I'm trying to say, sauce that nigga. kek
No seriously, I'm interested on an academic level.
Oh? Really? Please expound on the transmission method? I'd like to understand.
The name 'ultrasonic' implies sound so A+ for making that connection. There still needs to be a bi-directional medium for a microscopic level ultrasonic signal source inside a body to transmit return information out of the body to a receiver.
If you've ever had any body part ultrasonically scanned, you'd have noticed that the signal is almost unreadable ( reflections from inside the body) without the ultrasonic transmission gel that the head requires to facilitate the transmission of signals into the body and to receive the reflected signal back. That signal would be much higher level than a 0.1mm chip would be capable of re-transmitting from inside a body.
The medium required for the scans is ultrasonic transmission gel. What medium could facilitate a high resolution interface with a body and a remote receiver? Water comes to mind but you'd need to be submerged in it for that to work.
Had a bit of response issues with 9kun. sorry for the double post.
That's 2020
