Conducting rubber by nanotechnology
Do you like this story?
Takao Someya at the university's School of Engineering and his team has developed a rubber that is able to conduct electricity 570 times as high as commercially available rubbers. The material is the first in the world to solve the problems faced by metals which are conductive but do not stretch and rubber, which hardly transmits electricity. It is reported that it can pave the way for use in robots as an artificial stretchable "e-skin" that can feel temperatures, heat and pressure like humans. It can be used on the surface of steering wheels, which would analyse perspiration, body temperature and other data of the driver who drives a vehicle having steering fitted with this device and judge whether the driver is fit enough to drive. It can be used on top of a mattress for bed-ridden people, watching if some parts of the body were under constant pressure and deciding on when to tilt the bed to change the patient's posture to prevent bedsores. It can also find use in stretchable displays and also as elastic conductors.
