• Abstract: Constructing the new generation information processing system by mimicking biological nervous system is a feasible way for implement of high-efficient intelligent sensing device and bionic robot. However, most biological nervous system, especially the tactile system, have various powerful functions. This is a big challenge for bionic system design. Here we report a universal fully flexible neuromorphic tactile perception system with strong compatibility and a multithreshold signal processing strategy. Like nervous system, signal in our system is transmitted as pulses and processed as threshold information. For feasibility verification, recognition of three different type pressure signals (continuous changing signal, Morse code signal and symbol pattern) is tested respectively. Our system can output trend of these signals accurately and have a high accuracy in the recognition of symbol pattern and Morse code. Comparing to conventional system, consumption of our system significantly decreases in a same recognition task. Meanwhile, we give the detail introduction and demonstration of our system universality.
