The latest graphene ink news:
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.
In February 2018, Haydale, the University of Swansea and Wheelsure entered a collaboration to develop intelligent systems for transport and industrial applications using Haydale's graphene ink sensor technology, in order to extend Wheelsure's product range. Now, Haydale has confirmed that The University of Manchester's Graphene Engineering Innovation Centre ("GEIC") is set to join this collaboration.
The project aims to develop an intelligent new product pairing Haydale's functionalized graphene sensor technology with Wheelsure's failsafe locking solution. The sensor will be developed by applications engineers at the GEIC using Haydale's functionalised graphene. The project is expected to be showcased at the official opening of the GEIC in December 2018.
Haydale has announced the signing of a Joint Development Agreement ("JDA") between Haydale Technologies (Thailand) Limited ("HTT") and Thailand's Star RFID ("Star"). The JDA is for the parties to quickly co-develop both graphene and silver-based inks for the printed Radio Frequency Identification market ("RFID"). The co-development is expected to lead to a supply and collaboration agreement in the coming months.
The parties have already commenced development of a dedicated silver ink for Star and have a small paid-for project to carry out this work. Star has first right of refusal for any products arising from the JDA.
In a recent study, researchers from the Stevens Institute of Technology in the U.S have come up with an original idea - they designed a bionic mushroom that uses graphene to produce electricity. More accurately, the researchers have generated mushrooms patterned with energy-producing bacteria and an electrode network.
Many examples of organisms that live closely together and interact with each other exist in nature. In some cases, this symbiotic relationship is mutually beneficial. The research team wanted to engineer an artificial symbiosis between button mushrooms and cyanobacteria. In their vision, the mushroom would provide shelter, moisture and nutrients, while bacteria 3D-printed on the mushroom's cap would supply energy by photosynthesis. Graphene nanoribbons printed alongside the bacteria could capture electrons released by the microbes during photosynthesis, producing bio-electricity.
