The use of graphene in printed electronic devices has been the reason for rapid advancement in the field of wearable technology.
In a recent study by Researchers at The University of Manchester, flexible battery-like devices have been directly printed on to textiles by means of a simple screen-printing method.
The obstacle in realizing wearable technology at present is the way to power up devices without using complex battery packs. This can be overcome by using devices called as supercapacitors, which while functioning similar to a battery also enable swift charging for completely charging devices within a few seconds.
At present, Researchers have developed a solid-state flexible supercapacitor device by printing on cotton fabric by means of conductive graphene-oxide ink. The printed electrodes were observed to have exceptional mechanical stability as a result of the strong interaction between the textile substrate and the ink, which has been described in the 2D Materials.
The extensive potential of wearable technology can be tapped by further advancing the graphene-oxide printed supercapacitors. Further investigation and advancement can help realize applications such as high-performance sportswear for monitoring performance, lightweight military gear, innovative types of mobile communication devices, embedded health-monitoring devices and also wearable computers.
