Graphene-based wearable sensor monitors heart activity accurately and comfortably

Researchers at The University of Texas at Austin have developed a graphene-based wearable device that can be placed on the skin to measure a variety of body responses, from electrical to biomechanical signals.

The device is so lightweight and stretchable that it can be placed over the heart for extended periods with little or no discomfort. It also measures cardiac health in two ways, taking electrocardiograph and seismocardiograph readings simultaneously. The electrocardiogram (ECG) technique, a method that records the rates of electrical activity produced each time the heart beats. is rather well-known. Seismocardiography (SCG), a measurement technique using chest vibrations associated with heartbeats, is a bit less so. Powered remotely by a smartphone, the e-tattoo is the first ultrathin and stretchable technology to measure both ECG and SCG.

Vittoria to launch new range of graphene-enhanced bicycle tires

Italian bicycle tire manufacturer Vittoria Industries recently announced that it is launching a new range of products employing a second generation of its graphene-filler technology. The graphene supplier is assumed to be Perpetuus Carbon, as the two companies signed a long-term supply agreement for graphene materials.

It was said that while the first-generation generally enhanced the performance of tires, the new 2.0 graphene is functionalized to improve specific tire performances, targeting metrics like speed, wet grip, durability and puncture resistance. Vittoria mentions that graphene interacts with rubber by filling the space in between the rubber molecules, which has been verified to increase all positive performance metrics.

Graphene Flagship partners launch rocket to test the possibilities of printing graphene inks in space

Graphene Flagship partners, Université Libre de Bruxelles, University of Pisa and the University of Cambridge, in collaboration with the European Space Agency (ESA) and the Swedish Space Corporation (SSC), recently launched The Materials Science Experiment Rocket (MASER) into space. The objective is to test the printing of graphene patterns on silicon substrates in zero gravity conditions.

The experiment aims to test the possibilities of printing graphene inks in space. Studying the different self-assembly modes of graphene into functional patterns in zero-gravity will enable the fabrication of graphene electronic devices during long-term space missions, as well as help understand fundamental properties of graphene printing on Earth. This mission is also a first step towards the investigation of graphene for radiation shielding purposes, an essential requirement of manned space exploration.

Ultraviolet light on a graphene surface could eliminate toxic mercury in UV light devices

A research team led by professors Helge Weman and Bjørn-Ove Fimland at the Norwegian University of Science and Technology (NTNU) has succeeded in creating ultraviolet light on a graphene surface. This could be beneficial for eliminating the toxic mercury element common in ultraviolet light devices that are used to kill bacteria and viruses.

“We’ve created a new electronic component that has the potential to become a commercial product. It’s non-toxic and could turn out to be cheaper, and more stable and durable than today’s fluorescent lamps. If we succeed in making the diodes efficient and much cheaper, it’s easy to imagine this equipment becoming commonplace in people’s homes. That would increase the market potential considerably,” says PhD candidate Ida Marie Høiaas.

Emberion to launch a VIS-SWIR graphene photodetector

Graphene Flagship partner, Emberion, will be launching a VIS-SWIR graphene photodetector at Laser World of Photonics, from 24 to 27 June in Munich, Germany. The linear array covers a wide spectral range, detecting wavelengths from the visible at 400nm into the shortwave infrared up to 1,800nm. Traditionally, it would require both silicon and InGaAs sensors to image across this wavelength range.

Emberion estimates that replacing a system using silicon and InGaAs sensors with its graphene photodetector would result in a 30% cost reduction. Emberion's photodetectors combine graphene transistors with a light absorbing layer. Food inspection, plastic sorting in recycling, authentication of pharmaceutical products, agricultural field analysis, and non-invasive medical imaging are among the potential uses for this product.
