Energy harvesting might be a good way to go eventually. Temp differential maybe? Motion from eyeball moving? Blinking? I see lots of possibilities (couldn't resist)...

Thanks for weighin in, Jelle! I want to be the first to know when a contact lens maker (or more likely Google) hires you!

@Jelle, thanks for chiming in. That extra info. makes the story more complete.

I view this more of a whacky idea (than a cool idea), but what the researchers already accomplished in this is pretty amazing!

Hi Krisi,

The idea would be overnight charging in an adapted contact lens container:

Also, for our artificial iris we are using liquid crystal technology, which can have a power consumption as low as 1 microWatt per square cm. Classic LCDs have a much higher power consumption mainly because of the backlight.

Best regards,

Jelle.

@Descartes: True. I suspect many researchers take inspiration from SciFi, just as the Qualcomm XPrize is loosely based on the Star Trek tricorder.

Auto-focus contact lens

It seems that a much easier application would be to use a liquid lens and a distance sensor to produce a self focusing lens. The challenge, when driving, would be to avoid focusing on the automobile windshield and to focus on the road instead.

OK, the coil is in the lens now, I get that...where is the other coil and source of energy? (in a practical device)

A logical step in technological evolution for me but my daughter pointed out the Scifi series Continuum where contact lenses are taken to another dimension. Thinking back to some older Scifi shows, they already implied the use of tablets, video phones and tricoders. Maybe we should take a closer look at what SciFi shows us now. This may be soon the next gadget of technology.
