Neuromorphic Device: Indian Scientists Develop Innovative Pain-Sensing Technology   Introduction: Indian scientists have developed a neuromorphic device inspired by how the human body senses, responds to, and adapts to pain. This advancement holds the potential to revolutionize wearable technology and improve human-machine interactions. What is a Neuromorphic Device? A neuromorphic device mimics the human nervous system’s functions. Specifically, it replicates the role of nociceptors —special sensors in the human body that detect and respond to pain. When exposed to harmful stimuli, nociceptors trigger pain responses, helping the body react to dangerous situations. Habituation Process and Neuromorphic Functionality: Habituation in Humans: The body undergoes habituation with repeated exposure to the same pain-causing stimuli. Over time, the intensity of the pain felt decreases, allowing the body to tolerate certain stimuli better. Neuromorphic Devices: These devices simulate this ...
