I have been thinking about trying to make a ESP8266 board and SD Memory fit into a small form factor say 15mmx15mm the board would then be encapsulated. That is the easy part. powering the board I would prefer to have biocompatible wires to a inductive charging loop implanted on the bottom of the forearm with the board on the top of the arm. To power the device I would take a small Li-ion power pack and a inductive coil strapped to the underside of the fore arm much like a old ipod case. my concerns are heat generated by the esp chip and signal interference from the inductive power loop. Does any of this sound possible?
