A team of scientists have created semi-transparent photodetectors, improving the capabilities of eye-tracking devices.
Society is becoming increasingly reliant on image sensors. However, limitations in these sensors thus far have held back specific applications.
These photodetectors feature a large amount of built-in gain, meaning they can be placed far away without needing amplification. The high levels of gain are a big step since current organic light-sensitive conductors need amplification immediately, and the electronics that can do that are not transparent and need to be placed near the pixels. The new array from Mercier et al. can be printed onto glasses or other devices that sit immediately in front of the eye without blocking the view.
This research has powerful implications. It could improve eye-tracking autofocus abilities, open new opportunities for augmented and virtual reality, and much more.
