It is reported that the electric skin is designed by the biologists. The skin can be used on the robot or the artificial limb. Although this skin is still under experiment, it has the same reaction time as the real one. This research is a great progress for human, which is expected to replace the robot and artificial limb by updating to be more intelligent. People all know how to hold an egg. If we want to make a robot serve a meal, we are not willing to make it break the glass.
The electric skin is consisted of the nanometer wire. The prototype of the skin is forty nine square centimeters, which is able to sense the pressure of zero Pa to fifteen Pa. people need such pressure when they are typing on the keyboard. There is another method to make the electric skin have a sense of touch, namely connecting a rubber film, which can change the thickness with different pressure, and a capacitor to measure the change of pressure. However, this kind of rubber film is unable to stretch. Compared with the real skin, the reaction of this method is faster.
These great achievements can be the important milestone in the artificial intelligence field. In the aspect of people’s sensory substitutions the achievements of vision and audition are outstanding, while the sense of touch is an obstacle. Robots are unable to brush teeth or turn over the newspaper. The development of the electric skin will meet so many challenges, like the new sensor. The sensor produce response towards the constant pressure, but the sense of the real skin is more complicated. Besides, connecting the artificial skin and nervous system is very difficult.
The prototype of its design more likes a handheld device. This research is very useful for some special applications, for example, we can send the robot to environment of outer space which is dangerous for human beings. In this circumstance, we can make use of the robot to collect information. The related integrated circuit is TC74VCX16600FT.
