A group of engineers has discovered next generation smart garments at the University of Delaware.
It has been created on a range of fibres like nylon, cotton, and wool coated with pliable carbon nanotube composite. It has been published in “ACS Sensors” journal where they have mentioned and demonstrated the ability of smart garments to measure a wide range of force.
“Smart Garments” with this sensing technology can be used in the future to detect human motion. This could be achieved by attaching the sensors to the soles of shoes and clothing.
Carbon nanotubes give this lightweight, pliable, porous coating spectacular sensing technology. Electrical charges in the fiber can be measured when the material is compressed.
Nerve-like electrically conductive Nanocomposite coatings are made on filaments utilizing electrophoretic statement (EPD) of polyethyleneimine functionalized carbon Nano-tubes.
The films act almost like a dye coating just with the additional sensing technology. The Nanocomposite coating developed through EPD process creates a strong bond with the fibre surface and is highly stable.

Existing techniques like fibre-plating decreases convenience and endurance whereas this new sensing technology of nanocomposite material is pliable and pleasurable to the touch and has been tested on a wide range of fibres both natural and synthetic such as wool, spandex, polyester, etc. The coatings are 250-750 nanometers thick, about (0.25-0.75)% as thick as paper which is about less than a gram’s weight. High advantage of this coating is that it is eco-friendly and very less costly.
In future, the sensor-coated shoes can be used to measure pressure on people’s feet while walking. Physicians and doctors can analyze the imbalances and injuries. Athletes and sportsperson will also be benefited by this sensing technology.
