Researchers in China have developed an artificial robotic skin that mimics the sensory processing of the human nervous system. By using spiking circuitry, they created a system that interprets pressure input through electrical activity spikes. This approach takes cues from how our sensory neurons transmit signals, integrating them to provide the robotic skin with a more nuanced understanding of touch and potential injuries. The new skin features a flexible polymer embedded with pressure sensors. These sensors connect to the system using conductive polymers. When pressure is applied, the sensors generate short pulses of electrical current, or spikes. The system communicates information through several methods: the shape and magnitude of the spikes, their duration, and the frequency with which they occur. Notably, spike frequency serves as the primary means of conveying pressure information, while the other aspects help identify which sensor is active. By focusing on pressure sensing and using multiple processing layers, the researchers aimed to replicate some of the complex functions of human skin. This setup allows for preliminary processing of sensory information, potentially enabling robots to react to stimuli without needing direct input from a central controller, similar to how reflex actions operate in humans. The project represents a significant step toward developing more responsive and intelligent robotic systems that can interact with their environments in a meaningful way.
