I’m sure you’ve seen someone clap his hands and in just a blink of an eye, the room lights turn off. Mindblowing, right? Well, now, for a much lazier approach, one can literally just blink to do the trick!
Researchers from Georgia Institute of Technology and the Chinese Academy of Sciences in Beijing made a sensor that can fit on a pair of glasses. The sensor is made of numerous polymer layers with a thin metal coating that generates electricity. An electric signal is made when the person blinks and different combos of blinks can be used to assign different functions like to type, turn on fans and lights and many more.
While this sounds like something a really lazy individual would use (I'm looking at you), this is actually specially designed to help paralyzed or immobile persons. “The good thing about the technology is the high sensitivity, which may become particularly useful in places where the motion is very limited,” says Indian Institute of Science Associate Professor Ambarish Ghosh.
This type of “hand-free” technology has a lot of potential aid for people who have little to no movement of limbs like Stephen Hawking and those who suffer amyotrophic lateral sclerosis (ALS).
The researchers are even currently exploring further possibilities of intelligent robotics applications by using the sensor on different parts of the body. Wang adds that the entire sensor system can be self-powered if he and his colleagues can improve the level of signal generated.
But, again, with today's undeniable "indolence trend", this can be used to control the electrical functions of the house, text without even touching one's phone, and fulfill the humanity’s greatest pleasure by ordering food without even moving one's whole body.
