> Just want to make sure I understand what you're asking here; because it sounds to me like you're asking something along the lines of "Hey, the vibrating device is neat, but I'd actually like a device that can directly stimulate movement of the device wearer's muscle groups on reception of a remote signal. Can you do that?"

E-stim is already a thing, it just lacks (so far) the remote aspect.
