Scientists invent micrometers-thin battery charged by saline solution that could power smart contact lenses::Scientists from NTU Singapore have developed a flexible battery as thin as a human cornea, which stores electricity when it is immersed in saline solution, and which could one day power smart contact lenses.
Who doesn’t want everything you see to be recorded, all while getting an ad overlay directly over your eyes?
this type of technology could be revolutionary and restoring people’s eyesight as well
I could see some cool military applications for this too.
Contacts? Don’t you need to see for them to help
Some “blind” people do have data coming in, it’s just so blurry/skewed that it’s worthless. It might be possible to fix this but it would be a case by case basis and likely very expensive. Not all blindness is a world of black
Even totally blind people can usually detect light as painful, slightly less dark darkness. That’s actually why so many wear dark sunglasses
While pouring salt into your eyes to power it!
Saline is isotonic and, short of a large electrolyte imbalance, shouldn’t cause any/very little irritation to your eyes
Saline is what you are supposed to wash your eyes out with when you get something in them in addition to being what contacts are stored in every night
