wearable USB adapter?
Does anyone have a template (for making an adapter) for connecting to the USB pins while the watch is being worn? I'm imagining a "shim" only 1-2mm or so thick that clips onto the back.
The particular use case I'm looking at is a wearable EKG for fitness use. The EKG would have its own battery (and actually charges the watch) and possibly integrate other functions like a more accurate pedometer, respiratory rate, GPS, maybe even energy harvesting. It would implement ADK or ADB (the way boards like Kelly Wu and IOIO do) to send the data.
iOS: small selection of expensive devices, unfriendly to small developers and expert users
Android: wide selection of devices, very friendly to all developers and all users
Take your pick.
