Researchers develop washable, wearable graphene capacitors that can be woven directly into clothes

Researchers at the University of Cambridge and Jiangnan University in China have developed graphene-enhanced wearable electronic components incorporated directly into fabrics. The devices could be used for flexible circuits, healthcare monitoring, energy conversion, and other applications.

The researchers have shown how graphene and other related materials can be directly incorporated into fabrics to produce charge storage elements such as capacitors, paving the way to textile-based power supplies which are washable, flexible and comfortable to wear.

Paragraf starts producing graphene at commercial scale

Paragraf logo imageUniversity of Cambridge spin-out company, Paragraf, recently announced that it started producing graphene at up to eight inches (20cm) in diameter, large enough for commercial electronic devices.

Paragraf is producing graphene ‘wafers’ and graphene-based electronic devices, which could be used in transistors, where graphene-based chips could deliver speeds more than ten times faster than silicon chips; and in chemical and electrical sensors, where graphene could increase sensitivity by a factor of more than 30. The company’s first device will reportedly be available in the next few months.

Graphene shows promise for high-speed optical communications

Researchers affiliated with the Graphene Flagship have demonstrated novel high-speed graphene-based data communication at a data rate of 50 Gb/s. Integrating graphene sheets into silicon photonics could form the basis for next-generation data communications.

The team reports that robust detection in a wide range of NO2 concentrations, 10-154 ppb, was achieved, highlighting the great potential for graphene-based NO2 sensors, with applications in environmental pollution monitoring, portable monitors, automotive and mobile sensors for a global real-time monitoring network.

Talga reports positive initial test results on its graphene silicon lithium-ion anode

Australian advanced materials technology company, Talga Resources, recently announced positive initial test results from the development of its graphene silicon lithium-ion anode in the UK.

The results are the first under Talga’s UK Government-funded “Safevolt” project - a Talga-led program run in conjunction with consortia partners, Johnson Matthey, the University of Cambridge and manufacturing research group, TWI.
