Researchers from The Barcelona Institute of Science and Technology’s ICFO–Institut de Ciències Fotòniques have developed the first ever semi-transparent image sensor.
This sensor comprises an 8×8 array of semi-transparent photodetectors and electrodes disposed on a fully transparent substrate. Each pixel in the array is of size 60 x 140 μm and has an optical transparency of 85-95 percent, according to the study.
These photodetectors capture light while allowing a considerable portion of it to pass through— a necessary trait for applications where transparency is essential, such as in smart displays on AR and VR devices.
Additionally, this sensor sports a design that balances light capture with visibility, making it suitable for applications requiring both sensing capabilities and transparency. ...
