A research team from RMIT, Australia, has successfully developed a robot skin that can respond to pain and other stimuli like real skin. The team said it meant an important step forward in the field of intelligent machines and bionic prostheses. For example, this technology can let amputees know if they are picking up sharp or dangerous objects, and make the machine more durable and safe in a manned environment. < p > < p > researchers at the Royal Melbourne Institute of technology, Australia, point out that they have pioneered the creation of such devices that can provide feedback on pain stimuli with unprecedented fineness. Dr. MD ataur Rahman said: “we have created an essentially electronic somatosensory device that can replicate key features of the complex neurons, neural pathways, and receptor systems in the human body, thus driving our perception of stimuli.”. < / P > < p > although there are some technologies that can simulate different pain levels with the help of electrical signals, the new device can respond to the actual mechanical pressure, temperature and pain stimuli and provide the correct electronic response. < p > < p > for example, RMIT’s artificial skin can tell the difference between the pain of a finger touching a pin or accidentally sticking into a finger, which no other research team has ever done before. < / P > < p > it is understood that the RMIT team has been working on three independent sensing technologies. It’s made of a stretchable electronic material (biocompatible silicone) that’s the thickness of a thin sticker. < / P > < p > coated with a temperature sensing coating, it can respond to the change of heat, and has an electronic unit designed to mimic the information storage of the brain. Lead researcher Professor Madhu Bhaskaran said. < / P > < p > we always perceive things through our skin, but our pain response only occurs at a certain time, such as touching an overheated or sharp object. < / P > < p > to date, no electronic technology has been able to realistically mimic this pain sensation. RMIT’s artificial skin can respond immediately when pressure, heat, or cold reach painful thresholds. < / P > < p > in addition, through further work, the RMIT team believes that e-skin can one day also be used as an option for non-invasive skin transplantation. < / P > < p > Bhaskaran added: “we need further development to integrate this technology into biomedical applications. At present, it has the basic characteristics of biocompatibility and elasticity similar to skin. Global Tech
