Given that the user will typically have their watch on them as well, why not make the ring a battery-less BLE transmitter that triggers voice input on the watch? It’s still one-handed operation, but now the battery life is infinite since there’s no battery? The disposable ring seems like a solution in search of a problem to me, unfortunately.

I imagine the reason is reliability, but USD$99 plus international shipping every two years isn’t worth that to me, sorry.
Aside: I loved my kickstarter pebble and my steel, btw!
- margalabargala 10mo agoPiezo switches like the one you linked have a minimum size to generate the power necessary, and that minimum size is larger than the entire current ring.
- Daneel_ 10mo agoThe power generation portion of that switch is around 1.4x1.4cm and can power the transmitter to send a signal over 40m. I think it’s likely that it could be adapted into a ring form. See: https://core-electronics.com.au/attachments/uploads/TEL0173-1.jpg https://core-electronics.com.au/attachments/uploads/TEL0173-...
- margalabargala 10mo ago1.4x1.4cm is gigantic for a ring that is currently just a band. And to say nothing of the depth required. Even if you shrink it 50% the ring would be mostly power generation button.
- erohead 10mo agoShould be possible! Battery would last for decades in this mode.
