Graphene humidity sensors made with a CMOS-compatible process

Researchers at the University of Exeter have used CMOS-compatible processes to create graphene-based humidity sensors with performance on par with commercial ones. The process was demonstrated on an array of sensors produced on a 4” silicon wafer as well as on transparent and flexible PET. The work paves the way...

Graphene-alumina heterostructures show their strength

Heterostructures of graphene and other 2D or ultrathin materials have potential applications in sensing, electronics, and battery technology. For example, graphene transistors encapsulated with alumina (Al2O3) are of interest for flexible electronics, and graphene/metal oxide heterostructures are widely used in lithium ion batteries. The mechanical strength, properties and stability of...

Graphene chemical sensor shows unprecedented selectivity and discrimination

Researchers in the US have used Graphenea graphene to produce chemical sensors with selectivity and discrimination unseen before in any other sensor type. The sensors are made from untreated off-the-shelf CVD graphene, which makes them commercially interesting. The consortium of an army research center, an academic institution, and two private...
