If you can make the robot feel tactile, can sense temperature, stress, and even have nerve activity, then they will “unlock” more new skills. A few days ago, the world's first flexible artificial tactile nerve came out, making this idea a step closer to reality. Recently, Bao Zhenan of Stanford University, Li Taiyu of Seoul National University, and Xu Wentao of Nankai University jointly published a paper in the journal Science, reporting a highly sensitive biomimetic tactile nervous system based on flexible organic electronic devices. The artificial neural tactile system has good biocompatibility, flexibility and high sensitivity, and has application prospects in the fields of robot surgery and prosthetic touch.

Professor Xu Wentao from the School of Electronic Information and Optical Engineering of Nankai University said that the core problem and key point of this research is to design and implement an artificial system that works similarly to the biological nervous system and is compatible with biological neural signals. The system is very flexible. Based on the above assumptions, the joint research team of China, the United States and Korea used flexible organic materials to simulate a human tactile nerve. This artificial sensory nerve consists of three core components: a resistive pressure sensor, an organic ring oscillator, and a synapse transistor. The system first uses a series of susceptors to sense extremely subtle pressures and produce corresponding voltage changes, which are then converted into electrical impulse signals by ring oscillators (artificial nerve fibers). The electrical signals obtained by the plurality of ring oscillators are converted into synaptic currents by synaptic transistor integration, which in turn is transmitted to the next level of nerves.

"Functionally, this artificial nerve can mimic the tactile function of human skin and is compatible with the biological nerve signal. We have initially confirmed this compatibility." Xu Wentao said that this work is groundbreaking A flexible artificial sensing nerve is produced, and a hybrid reflex arc formed by artificial nerves and animal nerves is realized.

"Because of the compatibility of the sensory nerve with the living body nerve, it can be applied to the realization of the perception of the human limb system compatible with the human nervous system, and has potential significance for the treatment of nervous system diseases. At the same time, if the artificial nerve is applied In software robots, it can achieve human-like perception and replace people in extreme working environments," Xu Wentao said.
