Pain perception is a mechanism of animal self-protection. Recently, inspired by the mechanical enhancement of biological soft tissue strain, the team of scientists from Ningbo Institute of materials, Chinese Academy of Sciences developed a new type of bionic skin to realize the dynamic change from touch to pain perception** In biological system, soft tissue can avoid damage by effectively adjusting its mechanical strength through strain enhancement.
Access:
*The traditional electronic skin mainly uses pressure sensor *. By setting the pressure threshold, the system can make early warning and behavioral response to cope with greater pressure.
The soft tissue combined with the somatosensory system of the organism, can reach the controllable perception threshold transition from tactile to pain when the tissue or skin is stretched , and the response will be faster to prevent danger.
It is understood that researchers were inspired by the three-dimensional deformation of puffer fish skin** However, the current technological achievements are still a long way from applying bionic skin to organisms.
Researchers said that this technology is constantly approaching the structure of human skin, and future research will certainly achieve more functions of real skin. Future robots will also know pain**
