No charge, no battery and wireless wearable cooling jacket with WearGRAPH
23 June 2020As part of the EU’s Graphene Flagship initiative’s two-year project, WearGRAPH has developed a graphene-based, battery-free, wireless and flexible power supply for wearable electronic devices.
This new design overcomes problems associated with more traditional power supply modes in wearable electronic devices, including the difficulty of charging batteries and safety concerns.
The project, which was partnered by Graphene Flagship with the Dresden University of Technology and Interactive Clothing in Germany, was launched in 2018, and is a “self-sufficient wearable device using the high connectivity and flexibility of graphene in the textile industry with energy harvesting and energy storage.” reached its goal.
The unique features of the graph allow scientists to design a system powered by solar cells and super capacitors, eliminating the need for regular pauses for lithium-ion batteries or charging.
he device can communicate with a smartphone via an NFC antenna, which can be integrated with various applications.
The WearGRAPH team tested this technology on a cooling jacket.
E-COOLINE Powercool SX3 Shirt has been successfully equipped with its own climate monitoring system. The shirt has barometric pressure, humidity and temperature sensors, the system’s own charging sensors transfer data to the smartphone.
The result is a more efficient cooling system that does not require charging or wiring.
“The improved cooling jacket can be used for a wide variety of groups such as patients and workwear,” professor Xinliang Feng from TU Dresden, his partner Graphene Flagship, who led the WEARGraph project. Said.
“Technology has great potential to address various market segments such as fashion, sports, wellness, medical and the Internet of Things applications in general. It is now up to design engineers to take advantage of the wide variety of possible applications offered by the new technology.” Ali Shaygan Nia, group leader at TU Dresden, added.
