The latest graphene ink news:
Haydale is working alongside Swansea University, GTS Flexibles, Alliance Labels, Tectonic International, ScreenTec, Alliance Labels, Malvern Panalytical and the English Institute of Sport on a Welsh Government SMART Expertise program.
The program, funded by the Welsh Government as part of its European Development Fund, is intended to benefit industry in Wales through the development of new concepts and advanced functionalized inks using Haydale’s advanced materials.
Haydale has announced that it has signed a supply agreement to provide 76kg of its propriety piezoresistive ink to HP1 Technologies (HP1T) over an 18-month period. The value of the Supply Agreement was not disclosed.
HP1T creates bespoke flexible, printed, functionalized nano carbon-based sensor systems that can measure and collect high quality impact and pressure data. This newly signed supply agreement will see Haydale become HP1T's single supplier of functionalized nano carbon inks.
Circa Group’s bio-based solvent enables high-quality graphene inks made by the University of Manchester
Australia-based biotechnology company Circa Group has announced that UK-based University of Manchester has successfully produced graphene ink using Circa's bio-based solvent Cyrene. Circa said academics have described the material as the “highest quality conductive graphene ink ever reported”.
Currently, one of the most common and successful ways of producing graphene involves exfoliating graphite using sonication - a process in which sound waves are used to agitate particles in solution. This requires toxic solvents, which has led scientists to seek alternative production methods. According to Circa, the University of Manchester has now successfully produced graphene ink with Cyrene. The company also said that work by the University of York and the Spanish National Research Council showed that Cyrene had “near-ideal physical properties for graphite exfoliation and the production of graphene dispersions”.
Researchers from the University of Strasbourg & CNRS (France), in collaboration with Adam Mickiewicz University in Poznań (Poland) and the University of Florence (Italy), have developed a new generation of pressure sensors based on graphene and molecular “springs”. The researchers say that thanks to their highest sensitivity, these devices are ideally suited for health monitoring and point-of-care testing.
The team reports that many electroactive materials have been employed for this purpose. Among these, graphene has been the most studied because of its excellent electrical conductivity, exceptional mechanical properties and large surface area. The researchers rely envision applications of graphene-based sensors in the form of tattoos.
Haydale has announced that through its Taiwanese operation, Haydale Technologies Taiwan, it has started to supply commercial quantities of its functionalized graphene ink to a major print house in Taiwan. The graphene ink is used to print test strips in the self-diagnostic biomedical sensor device market for diabetes monitoring. Haydale believes its graphene ink is the first of its kind being used in volume in this market.
Following over a year of market testing, evaluation and gaining regulatory approvals, including extensive production quantity in-line testing, HTW has now started to deliver its graphene screen printed inks as part of a recent 100kg order secured from a leading Taiwanese printer. Haydale's graphene ink is reportedly proving to be a high quality, more stable, and consistent product, replacing the established graphite and carbon inks used extensively in producing the test strips for this significant global market.
