Cool idea...but how do you get energy to power the electronic contact lenses?

@Krisi: An integrated micro battery and/or energy harvester of course. Ambitious, I know!

Yeah, I know energy harvesting would be the best...but where do you put it? most harvesters require space, likely energy to be harvested is proportional to the volume of the harvester (or its surface)

Ben Krasnow sandwiched a coil between contact lenses and powered an LED while wearing it... in his GARAGE!

 

Check out the video, it is insane.

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

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.

@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!

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

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)...

@Caleb: Just think of what he could accomplished had he been working in the living room ;-)

Actually many innovations can be done on contact lenses its jusf one has to thinkover and keep on challengng.

More SciFi to become reality

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.

@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.

NEXT UPCOMING BROADCAST

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
