Researchers at the University of Massachusetts, Amherst, have created something that is a breakthrough in powering portable electronics. The team found a way to create an alternative fabric to batteries for portable devices. The technique involves embroidering a pattern of storing charges on any garment.
The method developed by the team uses a micro-supercapacitor and conductive wires covered with steam with a polymer film. A unique stitching technique creates a flexible mesh of electrodes aligned on a textile backing, resulting in a solid state device providing a large capacity for storing the electric charge for its size. The features of the energy storage device allow it to power portable biosensors.
The researchers involved in the project argue that while the components of the electronic circuits have been remarkably miniaturized over the years, the same miniaturization in the charge storage devices has not occurred. The new technique developed by researchers brings the necessary miniaturization to charge storage devices and shows that they can embroider a charge storage pattern on any garment using wire and the special processes that they created.
Textile scientists have already tried this vapor deposition process, but it was too expensive and technically difficult to use on a large scale. UMass Amherst's team said their research has proven that vapor deposition can increase and remain profitable.
The vapor phase coating process used by the team creates a porous conductive polymer film on highly twisted wires that can be inflated with electrolyte ions and that maintain a high charge storage capacity per unit of charge. length. Scientists are currently working to integrate this new fabric load storage device into smart, portable clothing that uses electronic textile sensors and low-power microprocessors to monitor a person's gait and movement.
