The company is now in the process of finalising its flexible PCB design that will accommodate all the sensors, components and battery within the casing of the ring. It's worth noting that the company is developing their own designs rather than using off-the-shelf designs from Chinese manufacturers. Most of these smart rings use Bluetooth Low Energy (BLE) or NFC to connect to devices around, but Fin will use…
