Release date: 2015-11-20 Two research groups from the United States and South Korea have independently developed an artificial electronic skin. The material not only can experience changes in heat and cold, but also detect extremely subtle pressures, and it is expected to develop wearable devices and prostheses with "tactile" in the future. The development of prosthetics has come a long way. Nowadays, the latest prosthetic devices have been able to connect with the nervous system, and can even directly control them through brain signals, greatly improving the quality of life of disabled people and helping them to acquire a certain degree of independent living ability. However, scientists are not willing to stop there. They hope to develop skin-like materials to help physically disabled people regain their sense of touch. Bao Zhenan, a chemical engineer at Stanford University in the United States, spent nearly 10 years researching electronic skin, hoping to make it have the characteristics of human skin. A few days ago, she and her research team used an organic electronic material to create an artificial mechanical receptor system. This system, called digital haptics, consists of two layers of thin plastic sheet material. The top layer contains carbon nanotube sensors and the lower layer has flexible circuitry. After the carbon nanotube sensor senses the pressure, the flexible circuit can emit a pulse signal to send information to the nerve cells. The Ulsan National Institute of Science and Technology in Korea has developed a skin-like substance that can detect weak pressure and heat, mainly made of plastic and graphene polymers, and is similar in principle and structure to the United States. Researchers say the electronic skin they developed has a very high sensitivity to detect the pressure of water droplets and the moment the hair is swept away. In addition to prosthetic limbs, these materials are also widely used in the field of wearable medical diagnostics. The team has integrated the digital haptic system into a pair of gloves to accurately reflect the pressure of the hand when grasping; the Korean team Using the electronic skin they developed, they created a wristband that monitors blood pressure. Editor-in-chief It took billions of years for earth creatures to evolve skin with clear touch; now, intelligent humans use new materials to simulate nature. Plastic sheets, carbon nanotubes and graphene are all carbon-based materials that were invented in the last hundred years. We still don't know if they can approach or even surpass the miracle of life, but it is amazing enough for scientists to get out of this step. From the era of mechanical technology to the era of life science and technology, it is inseparable from such keen new tools.
