Scientists from the University of Massachusetts in Amherst have discovered a technique by which a charge-storing system can be manufactured. This system reportedly can be incorporated with minimum efforts into clothing, in order to impart a charge storing pattern on wearable device.

Since a long time, a key drawback that was stunting the manufacturing of biosensors integrated as wearable device for monitoring health involved non-existence of a lightweight and long-lasting power supply. However, scientists and researchers at the University of Massachusetts designed the above-mentioned system that can provide a solution for lack of such a power supply.
The team was led by materials chemist Trisha L. Andrew. According to her, batteries and other kinds of charge storing devices are made of components that limit the process of electricity transfer in wearable, portable, and flexible technologies. Moreover, the devices also could exist in a combination of large and heavy components, thus making it difficult to transport them. In contrast to this, the new method developed makes use of a micro-supercapacitor, wherein vapor-conductive threads are combined with polymer films using a special sewing technique.
Super capacitors have been identified as suitable candidates for developing wearable charge storage circuits. This is because of their inherently high power densities compared to batteries. This led to the creation of a mesh of electrodes aligned with each other on a textile surface. The entire process consequently gave way to a solid-state device that has an ability to store anelectrical charge, thereby able to provide electrical power to wearable biosensors.
The team of researchers has miniaturized various electronic circuit components in this scientific study. By simply sewing circuits on self-powered smart garments, a new revolutionary way of using biosensors is now possible. The details of the study can be checked online in the ACS Applied Materials & Interfaces.
