The sensors can monitor a person’s various movements and expressions and are sensitive enough to distinguish between laughter and laughter and even detect swallowing speed.
Researchers at the Indian Institute of Technology Guwahati have developed a fancy water-resistant material that can be used for real-time monitoring of human movements. The developed material is flexible, non-stretch and environmentally friendly which can detect low strain with high sensitivity.
Wearable motion sensors are used for physiological monitoring of human movements. These sensors are used for gait analysis, understanding human and machine interactions, and monitoring patients during the rehabilitation process. Such motion sensors are usually made of material that modifies mechanical strains that can be detected by electrical signals emanating from movement.
To be used as a wearable motion sensor, the strain sensing material must be flexible, strong and highly sensitive to both large and fine movements. The research team has developed a component that is superior to existing strain sensors in both sensitivity and durability.
The research team was led by Uttam Manna, Associate Professor, Department of Chemistry, Center for Nanotechnology and School of Health Sciences and Technology, IIT Guwahati and Professor Roy Paili, Department of Electronics and Electrical Engineering, Center for Nanotechnology and School of Science. And Technology, IIT Guwahati.
The results of their novels and unprecedented work have recently been published in the renowned peer-reviewed journal Materials Horizon. Uttam Manna and Professor Roy Paili from IIT Guwahati co-authored the paper with Supriya Das, Rajan Singh, Abhijit Das, Sudipta Bag.
