Researchers develop a graphene-based wearable strain sensor that can detect and broadcast silent speech

Researchers from the University of Cambridge, University College London, Imperial College London, Kumoh National Institute of Technology (KIT) and Beihang University have developed a wearable ‘smart’ choker for speech recognition, that has the potential to redefine the field of silent speech interface (SSI) thanks to embedded ultrasensitive textile strain sensor technology.

Where verbal communication is hindered, such as in locations with lots of background noise or where an individual has an existing speech impairment, SSI systems are a cutting-edge solution, enabling verbal communication without vocalization. As such, it is a type of electronic lip-reading using human-computer interaction. In their recent research, the scientists applied an overlying structured graphene layer to an integrated textile strain sensor for robust speech recognition performance, even in noisy environments.

Researchers develop method for optimizing both the growth and the transfer process of graphene

A team of researchers from the University of Cambridge, RWTH Aachen University and the National Institute for Materials Science in Japan has developed a methodology for simultaneously optimizing the growth and the transfer process of graphene, showing that it is possible to dry-transfer graphene with high-yield, if the crystallographic orientation of the growth surface is chosen appropriately.

Graphene often needs to be transferred from the growth substrate (typically copper) to a final substrate where components can be built. However, current transfer approaches either lead to a substantial degradation of the crystal quality or are not compatible with high-volume manufacturing. Moreover, while graphene has great potential for next generation electronics, the gap between the performance of “hero devices” realized in research labs and what can be reproducibly fabricated with scalable approaches remains large. This is why high-end electronic devices enabled by graphene are still not on the market – and why scalability is such a challenge in terms of making the most of this nanomaterial.

Various graphene technologies to be tested during moon and space missions

Graphene Flagship Partners University of Cambridge (UK) and Université Libre de Bruxelles (ULB, Belgium) collaborated with the Mohammed bin Rashid Space Centre (MBRSC, United Arab Emirates) and the European Space Agency (ESA) to test graphene on the Moon. This joint effort sees the involvement of many international partners, such as Airbus Defense and Space, Khalifa University, Massachusetts Institute of Technology, Technische Universität Dortmund, University of Oslo, and Tohoku University.

The Rashid rover is planned to be launched today (30 November 2022) from Cape Canaveral in Florida and will land on a geologically rich and, as yet, only remotely explored area on the Moon’s nearside – the side that always faces the Earth. During one lunar day, equivalent to approximately 14 days on Earth, Rashid will move on the lunar surface investigating interesting geological features.

Researchers design impressive all-in-one miniature spectrometers using graphene and Mos2

An international team of researchers, including ones from Aalto University, Shanghai Jiao Tong University, Zhejiang University, Sichuan University,  Oregon State University, Yonsei University and the University of Cambridge, have designed a miniaturized spectrometer made of a ‘sandwich’ of different ingredients, including graphene, molybdenum disulfide, and tungsten diselenide. 

The spectrometer reportedly breaks all current resolution records, and does so in a much smaller package, thanks to computational programs and artificial intelligence. The new miniaturized devices could be used in a broad range of sectors, from checking the quality of food to analyzing starlight or detecting faint clues of life in outer space.

Researchers control the relaxation time of graphene

Researchers from CNR-IFN, Politecnico di Milano, the University of Pisa, the Graphene Center of Cambridge (UK) and ICN2 of Barcelona (Spain) have shown that the relaxation time of graphene charge carriers can be significantly modified by applying an external electrical field.

Graphene is able to efficiently absorb light from the visible to the infrared through the photoexcitation of its charge carriers. After light absorption, its photoexcited charge carriers cool down to the initial equilibrium state in a few picoseconds, corresponding to a millionth of a millionth of a second. The remarkable speed of this relaxation process makes graphene particularly promising for a number of technological applications, including light detectors, sources and modulators.
