Graphene elastomer exceeds sensitivity of human skin

Graphene Uses

Researchers from the Monash University have discovered a new sponge-like material called graphene elastomer. This revolutionary material could have diverse and valuable real-life applications, the applications for this type of technology are limitless. Not only can it lead to developing better, softer robots which can, for example, aid in healthcare or take care of the elders, but it can create a new generation of skin prosthetics. Right now, despite the great advancement in prosthetics provided by 3D printing, skin prosthetics still remain a challenge due to their lack of sensitivity but by Graphene elastomer technology can highly sensitive prosthetic hands.

Graphene’s superconductive power has finally been unlocked, and it’s crazier than we expected

by Fiona MacDonald, Science Alert

Okay, wow

It’s official: graphene has been made into a superconductor in its natural state – which means electrical current can flow through it with zero resistance.

Last year, physicists managed to do this by doping graphene with calcium atoms, but this is the first time researchers have achieved superconductivity in the material without having to alter it. And the results so far show that the material achieves an incredibly rare type of superconductivity that’s even crazier and more powerful than scientists expected.

MIT creates 3D printed graphene that’s lighter than air, 10X stronger than steel

by Lucas Mearian, Computerworld

The research also disproved that 3D graphene could replace helium in balloons

MIT researchers have been able to use graphene to print 3D objects with a geometry that has 10 times the strength of steel but only a fraction of the weight.

The discovery using the strongest material there is has the potential to enable lightweight products for airplanes, cars, buildings and even filtration devices because of the printed objects’ porous designs.

Graphene enhances wifi hardware for unprecedented speed and efficiency

Graphene Uses

Swiss researchers from EPFL have produced a tunable, graphene-based device that could significantly increase the speed and efficiency of wireless communication systems. Their system works at very high frequencies, delivering unprecedented results. Because the current technologies available like MEMS and MOS, using silicon or metal, do not work well at high frequencies. And that’s where data can travel much faster but the new graphene-based solution, which was developed in the “Nano-electronic Devices Laboratory” is designed to replace tunable capacitors which the backbone of wifi and found in all wireless devices.

Silly Putty makes for Super-Sensitive Sensors

by Sophie Bushwick, Popular Science

ADD GRAPHENE TO GET DETECTORS THAT CAN MEASURE BREATHING, BLOOD PRESSURE—AND SPIDER FOOTSTEPS

It’s easy to dismiss Silly Putty as a kid’s toy. But the stretchy material actually exhibits some surprising properties: It’s one of the softest plastics around, and it can behave like both a liquid and a solid, oozing when gently stretched but bouncing off surfaces like a rubber ball when hurled. And when you mix Silly Putty with graphene—strong, conductive carbon sheets with unusual physical properties—it becomes an incredibly sensitive strain detector that can track blood pressure, heart rate, and even a spider’s footsteps.
