Bengaluru's JNCASR Scientists Develop Smart Wearable System That Can Detect Stress

Scientists from the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) in Bengaluru have developed a novel wearable device that can detect stress.

The device uses a silver wire network on a stretchable material to sense strain and mimic pain perception. This technology adapts its electrical response based on the strain, much like how our bodies respond to repeated pain over time.

A stretchable device that responds to strain much like the human body reacts to pain, emulating adaptive and habituation behaviours to modulate pain responses intelligently.

When this stretchable material is stretched, small gaps appear within the silver network, temporarily breaking the electrical pathway. An electric pulse can then prompt the silver to fill these gaps, reconnecting the network and essentially "remembering" the event. Each time it is stretched and reconnected, the device gradually adjusts its response, much like how our bodies adapt to repeated pain over time. This dynamic process enables the device to mimic memory and adaptation, bringing humans closer to materials that respond intelligently to their environment.

Key Features:

Neuromorphic Device: Inspired by the human nervous system, this device mimics the functions of neurons and synapses

Adaptive Response: The device can sense strain and adjust its response, essentially "remembering" the event each time it is stretched and reconnected.

Potential Applications: This technology could lead to advanced health monitoring systems that provide real-time feedback to doctors or users. It could also improve robotic systems, making them safer and more intuitive to work with humans.

This innovation represents a significant step forward in wearable technology, offering new possibilities for health monitoring and human-machine interactions.

This innovative work is published as a research in the journal Materials Horizons, Royal Society of Chemistry (RSC) could lead to more advanced health monitoring systems that "feel" stress like the human body and adapt in real-time, giving feedback to doctors or users. Such technology could also improve robotic systems, helping machines become safer and more intuitive to work with humans.
