Hairy Electronic Skin Will Soon Let Robots Feel

Kahp-Yang Suh along with colleagues at Seoul National University, South Korea introduced the concept of hairy electronic skin that can detect faint vibrations. The touch sensor is developed by thousands of polymer nanohair woven together akin to the interlinked cellular structure in humans. These 50nm wide hairs have the ability to show movement on application of external force. Hence, any external activity such as a mild air pressure or a faint heart beat leads to twist and turns in the nano-hair resulting in their contact with each other. This contact generates electric current which is identified as a specific change in pressure, shear or torsion by the sensor. The result of the sense can then be displayed on a monitor in real time.

The Electronic Skin Which Will Soon Add Senses To Robots
This so developed electronic skin would soon add life to robots. These robots will have senses powerful enough to detect a slight touch, mild heartbeat and every other physical change that is mild to be felt by humans.
