Graphene-based stress sensor could help NASA in testing anxiety levels of astronauts

A new graphene-based sensor that measures stress via cortisol in sweat could be used by NASA to gauge the anxiety levels of astronauts.

Graphene-enhanced stress monitor to help NASA image

Developed by Caltech assistant professor of medical engineering, Wei Gao, the device features a plastic sheet etched with a laser to generate a 3D graphene structure with tiny pores in which sweat can collect. Those pores create a large amount of surface area in the sensor, which makes it sensitive enough to detect compounds in the sweat that are only present in very small amounts. Those tiny pores are also coupled with an antibody sensitive to cortisol, allowing the sensor to detect the compound.

UK-based rocket company Orbex develops graphene-enhanced rocket

Orbex, a UK-based private, low-cost orbital launch services company, has developed what it calls an "advanced, low carbon, high performance micro-launch" rocket called "Orbex Prime" and states that it already has a customer to fly on it.

Built with 3D-printed engines and a carbon fiber-and-graphene body, Orbex Prime will utilize renewable "bio-propane" as its fuel of choice. The two-stage rocket will be designed to carry up to 150 kilograms of payload, contained within a 1.3-meter fairing, into Sun Synchronous Orbit. Orbex even says its Prime rocket will be "80% reusable", although it is rather unclear how this would be executed.

Versarien selected for Airbus-backed Graphene Flagship project

Versarien LogoThe Graphene Flagship recently launched an Airbus-Backed Project for graphene-based thermoelectric ice protection systems. Now, Versarien announced that it has been selected to participate in that project.

The Project, which is categorized by the Graphene Flagship as a “Spearhead”, large-scale commercialization project, aims to develop graphene-based thermoelectric ice protection systems and to advance the technology readiness level of graphene in these systems.

New Graphene Flagship "Spearhead Projects" get €92 million in funding

The Graphene Flagship has announced the launch of eleven new "Spearhead Projects", each developed to take graphene-enabled prototypes to commercial applications. Now, the Graphene Flagship has committed €45 million to invest in eleven commercialization projects led by key industrial partners in Europe such as Airbus, Fiat-Chrysler Automobiles, Lufthansa Technik, Siemens, and ABB. Notably, the project partners will also co-fund the projects with a further combined contribution of €47 million, showing their interest in the development of graphene-enabled products.

The newly launched projects combine the results of the Graphene Flagship's innovative scientific research with the ambitions of commercial partners for marketable applications. This initiative will bring the number of companies involved in the Graphene Flagship to 78, which makes up nearly half of the whole consortium.

Graphene Flagship launches Airbus-Backed Project for graphene-based thermoelectric ice protection systems

The Graphene Flagship has announced the GICE Spearhead Project - development of a graphene-based thermoelectric ice protection system, that will aim to advance the technology readiness of graphene in such applications.

If ice accumulates on the wings, propellers or other surfaces of an aircraft, control can be dangerously inhibited. Thermoelectric ice protection systems prevent this from happening, using an ultra-thin conductive coating layer to generate heat when current is applied. The GICE project will attempt to use graphene to improve existing technology for this application.
