A group of researchers from the Georgia Institute of Technology has successfully developed a new sensor device, which has the potential to transform mechanical pressure into light signals.

The team has been seeking to put people's signature in small lights, the report said. The light signals into which the mechanical pressure from a fingerprint or a signature is converted could be caught. It has been told that these could be optically processed.

According to the findings, a mock sense of touch could be offered by the sensor device. Thereby, it would provide sensitivity, which could be compared to the sensitivity of human skin.

It is being said that the device offers a new principle to image force, by which parallel detection is used and many complications of existing pressure sensors are avoided.

The new technique could even be used in micro-electromechanical (MEMS) and biological imaging systems except for collecting signatures and fingerprints. At the end of the day, it would probably provide with a new method for human-machine interfaces.

"You can write with your pen and the sensor will optically detect what you write at high resolution and with a very fast response rate", in the words of Hightower Chair in the School of Materials Science and Engineering, Zhong Lin Wang.
