I’d be interested to see a battery-less ring that uses the mechanical energy of the press to power a BLE transmitter to trigger voice input on a watch. I feel like it’s much safer, plus it has no fixed lifespan.

How will a single press provide that much energy?
Piezo
It's a single press, which has to power the microphone for several seconds, and wireless connection to communicate with the sync device, even later if it isn't immediately available. In what way would piezo generate that much energy?
