Touch Bionics has been at this bionic prosthetics business for a while now, already providing i-Limb solutions to those deprived of the use of their hands or arms . The company’s latest innovation is to reduce all that tech down to the level of individual fingers, with its freshly announced ProDigits being able to replace anywhere between one and all of your precious little piggies. Relying on a traditional myoelectric regime — which reacts to muscle signals from the residual hand — or pressure from the remnant finger for its input, this invention can even be tweaked by doctors (over Bluetooth) to adjust the finer motor functions on a per patient basis.
