With you on this, haha. Big tech has heavily crowded the wearables space, with questionable intentions and uses of personal health data.

Additionally, when doing research around kinetic / thermal energy harvesting technology for a wearable design project (gesture recognizing smart ring) for school, we found modules to have far too low a volumetric energy density (W/mm^3) to be useful, where size matters more than anything else.

Musical instrument design is a well saturated space as well…

Yeah, thats sort of the point. :)

Big Tech may have crowded the wearables space, but Garmin is still quite a player in that field and the description "Big Tech" seems almost as bad a fit for them as "Olathe tinkerer collective" would be.

Have you ever thought of a commercial location tracking solution based off this tech? It’s another heavily, heavily crowded industry, but it has oddly high margins, and a basically-infinite battery life would be a huge selling point
