I'm working on designing my own smart ring, and I want it to be similar in size to the Oura Ring. I'm aiming for a design that features a single button and USB-C charging for tracking arm movements. Here are the parts I'm considering: a microcontroller, an IMU, a LiPo battery, a LiPo battery charger (like a TP4056), and a tactile switch. I'm really new to this, so I could use some guidance on whether these parts are suitable and if I'm missing anything. Any help would be appreciated!
