Could one use this as a sense-prothesis (without a motor)?

How small can the probe head get? Can I tape it to my ringfinger? Any health hazzards?

My first try would be taping it to my finger and listening to the signals enveloped mapped to my audible range.

Could be indeed! Augmented sensing, there's definitely something one can do. A ping (radar-like) every 5s, and in time you listen to echoes. The more intense, the higher the frequency. Ping me through the contact in the doc if you're keen on discussing about this!

Actually I fear 5s is far too slow to develop a sense-like feel for it :/

But thank you for the offer to discuss more :)
