Just what we need…robots that can stare at you. Japanese researchers have created a new artificial eye that works like a human eye, using solar cells to see colors and movement with 82-percent accuracy. The device, called an optoelectronic artificial synapse, uses two dye-sensitized solar cells, one for blue light and one for red light, to detect light wavelengths as small as 10 nanometers apart. It doesn’t need external power, making it energy-efficient, and mimics the human retina by sending positive or negative signals based on light input.
This allows it to recognize patterns and perform basic computing tasks, like logic operations, without extra hardware. Unlike traditional cameras that capture every detail and use lots of power, this eye filters information like a human eye which could help robots, self-driving cars, or wearable devices see better. The technology, tested with light pulses, could lead to more efficient vision systems in the future.
