An artificial skin sensing temperature and pressure can transmit signals 1000 times quicker than humans. One day, the skin can be used to cover prothesized bodies so that individuals can better use it or use it in robots.
The artificial skin, made from physical sensors, which can detect pressures, bends, and temperature, was developed by Benjamin tee of Singapore University. The skin consists of 1-millimeter square sensors, rubber or plastic composite material.
The sensors in the body convey electrical pulses back to a receiver when the skin presses on something. The single pulses of each sensor can identify the sensors, which means that the single recipient can combine multiple signals, accelerating delivery. All sensors are interconnected by a single wire, which means that measures are taken simultaneously across the skin. “Most electronic devices are, in comparison, synchronous, which means that each sensor must be scanned once at a moment,” Tee suggests. “Every sensor requires time to scan one by one. If you have 1000 sensors, with every 1 millisecond, it takes 1 full second for the entire scan operation. “Humans ‘ skin sensors send signals less than 1kHz or 1000 times a second at a maximum frequency. Tea sensors, by comparison, send 9Mhz, or 9 million times per second, back signals.
“Our skin immediately sends electric signals for processing when, for instance, we touch a cup of coffee,” he said. “The data is transmitted via the nerves; we actually do have a lot of it over 150,000 kilometers (150,000 kilometers) of the nerves of every human being.” One was reactive to rapid and dynamic modifications. Another reacted to static forces and generated signals that increased with enhanced power and a third sensed temperature.
Tee and his co-workers then placed the skin in a prothesis hand, grabbing a warm cup of coffee and finding that all three sensations are registered.
This] could make robots with whole-body skin as much easier and as many as humans do,” Tee suggests. Another use of this technology could be advanced prostheses and give people sensation.
