Researchers at IIT Guwahati develop water-repellent materials for wearable motion sensors

Water-repellent material developed by IIT Guwahati researchers can be used to track a person’s movements in the real world. Low strains can be detected with high sensitivity with this new material because it is flexible, non-stretchable, and safe for use in the environment. For various and more realistic applications, it is possible to imitate a superhydrophobic and conductive pattern interface. Health care, human-machine interaction, and even energy harvesting hold great potential for new gadget development with an unconventional user interface. The sensor was so sensitive that it could tell the difference between a smile and a chuckle, as well as swallowing motion.

Indian Institute of Technology (IIT) Guwahati researchers have created a new water-resistant polymer that can be used to track a person’s every motion in real-time. Flexible, non-stretchable, and environmentally friendly, the new material is susceptible to detect even minor stresses.

Wearable motion sensors can be used to keep tabs on your health by tracking your movements. Human-machine interactions and patient monitoring are all aided by these sensors, which are utilized for gait analysis and other tasks. Typically, motion sensors are constructed of materials that transform mechanical strain from movement into detectable electrical signals.

According to the researchers’ findings, their new material is more sensitive and long-lasting than other strain sensors now available on the market.

Associate Professor Dr. Uttam Manna of IIT Guwahati’s Department of Chemistry and Prof. Roy Paily of IIT Guwahati’s Department of Electronics and Electrical Engineering headed the research team. Dr. Paily also served as the Center for Nanotechnology and the School of Health Science and Technology director.

In the prestigious peer-reviewed journal Materials Horizons, their groundbreaking research has just been published. The paper was co-authored by Dr.Uttam Manna and Prof. Roy Paily, and IIT Guwahati’s Supriya Das, Rajan Singh, Avijit Das, and Sudipta Bag.

According to Dr. Uttam Manna, Associate Professor of Chemistry at IIT Guwahati’s Centre for Nanotechnology and School of Health Science and Technology, “transform mechanical deformation into electrical signals” to explain how their device works. Material’s gauge factor – the relative change in electrical resistance to mechanical strain – determines how well mechanical deformation is converted into an electrical signal. High gauge factor sensors are more sensitive because of this.

The stretching capability of the material has been employed to measure strain in wearable strain sensors till now. To create these sensors, scientists used polymers or textiles embedded with nanoparticles of particular materials. Motion sensors wear out and fail because of the continual straining they undergo.

The team used a chemically reactive paper and applied the ink in a precise pattern to test their metal-free, chemically reactive, and conductive ink. The IIT Guwahati team’s patterned interface was discovered to be abrasion-tolerant, extremely water-repellent, and strain-sensitive. It had a high gauge factor of roughly 18,300 with a 0.2 percent applied strain and responded within eight milliseconds to the mechanical force used. For a long time and after numerous cycles of operation, the material remained stable as well.

describing the applications for the sensors A Bluetooth module and an electronic component was connected to the ink-patterned paper and various regions of the human body, according to Dr. Uttam Manna, “enabling wireless monitoring of various human actions and expressions.” Finger, knee, and different regions of the face were all used to identify bending actions. The faces were all used for facial expression detection.

The sensor was so sensitive that it could tell the difference between a smile and a chuckle, as well as to detect swallowing motions,” continued Dr. Uttam Manna. The pattern interface was attached to the wrist and permitted wrist pulse monitoring; the material’s exceptional water resistance makes it appropriate for usage underwater as well.”

Existing designs for superhydrophobic and conductive pattern interfaces have enormous promise for new and more realistic applications. This is because they are simple. The IIT Guwahati team’s unorthodox interface has the potential to create gadgets in various fields, including healthcare, human-machine interactions, and energy harvesting.
