Engineers have developed a wearable sensing chip that can measure the concentration of cortisol – the stress hormone – in human sweat.
Graphene is an atomic crystal made up of carbon atoms arranged in a hexagonal lattice. It is considered as the thinnest, the strongest and the lightest material discovered. It has a vast variety of practical applications in the creation of new materials.
By using 3D aerosol jet-printing to put perovskites on graphene, scientists have made X-ray detectors with record sensitivity that can greatly improve the efficiency and reduce the cost.
Scientists report that they have developed conductive inks that allows users to "write" circuits almost anywhere — even on human skin.
Researchers have built a low-cost multiplex test that can rapidly provide three different types of data on COVID-19.
Scientists have created a prototype garment to demonstrate dynamic thermal radiation control within a piece of clothing by utilising the remarkable thermal properties and flexibility of graphene.
An international team of scientists have discovered a new material that can be 3D printed to create tissue-like vascular structures. In a new study, researchers have developed a way to 3D print graphene oxide with a protein which can organise into tubular structures that replicate some properties of vascular tissue.
Graphene electrodes could enable higher quality imaging of brain cell activity.
