Actually, you might be onto something here. Who knows, maybe there are those in the real mix of the work that's going on who even think this...
It may be that the first, easiest solution that can be implemented will be a contact "lens" that's sole function is to sense ciliary muscle contraction (focusing muscle) using a piezo sensor, and to transmit that info to an external device - eyeglasses. And then the eyeglasses do all the heavy lifting, since they can have a battery or in some way provide more power for various functions that a contact lens could.
It's relatively easy to "sense" almost anything with very, very low power consumption. "Consumption" translates to an energy requirement. Things that require significantly more power include wireless communication and electro-mechanical displacement. But of course, the ultimate in ultra-low-power electro-mechanical displacement is MEMS (Micro-Electro-mechanical Systems), exactly what EPGL specializes in... along with the "bio." And power consumption for wireless communication can be pretty low when the transmission range is only a few centimeters or less.
