Manchester scientists develop graphene sensors that could revolutionise the Internet of Things

Researchers at The University of Manchester have devised graphene sensors embedded into RFIDs, which have the potential to revolutionise the Internet of Things (IoT). By layering graphene-oxide (a derivative of graphene) over graphene to create a flexible heterostructure the team have developed humidity sensors for remote sensing with the ability to connect to any wireless network. Graphene was … Continue reading “Manchester scientists develop graphene sensors that could revolutionise the Internet of Things”

Electrons flowing like liquid in graphene start a new wave of physics

A new understanding of the physics of conductive materials has been uncovered by scientists observing the unusual movement of electrons in graphene. Graphene is many times more conductive than copper thanks, in part, to its two-dimensional structure. In most metals, conductivity is limited by crystal imperfections which cause electrons to frequently scatter like billiard balls … Continue reading “Electrons flowing like liquid in graphene start a new wave of physics”

Researchers printed graphene-like materials with inkjet

An international research team has developed inks made of graphene-like materials for inkjet printing. New black phosphorous inks are compatible with conventional inkjet printing techniques for optoelectronics and photonics. Since the discovery of the Nobel Prize winning material graphene, many new nanomaterials promise to deliver exciting new photonic and optoelectronic technologies. Black phosphorous is a … Continue reading “Researchers printed graphene-like materials with inkjet”

Super-light graphene and ceramic metamaterial possesses high strength, other attributes

WEST LAFAYETTE, Ind. — A new featherweight, flame-resistant and super-elastic “metamaterial” has been shown to combine high strength with electrical conductivity and thermal insulation, suggesting potential applications from buildings to aerospace. The composite combines nanolayers of a ceramic called aluminum oxide with graphene, which is an extremely thin sheet of carbon. Although both the ceramic … Continue reading “Super-light graphene and ceramic metamaterial possesses high strength, other attributes”

Graphene Electronic Tattoo Sensors can be applied to the skin with water

Researchers have designed a graphene-based tattoo that can be directly laminated onto the skin with water, similar to a temporary tattoo. But unlike a standard temporary tattoo, this new Graphene Electronic Tattoo is nearly transparent. The graphene tattoos work like wearable electronic devices, enabling biometric uses. It has been successfully applied to measure electrocardiogram (ECG), … Continue reading “Graphene Electronic Tattoo Sensors can be applied to the skin with water”
