Researchers find crystals of indium selenide have exceptional flexibility

Posted by in categories: electronics, materials

A team of researchers affiliated with multiple institutions in China and one in the U.S. has found that semiconducting crystals of indium selenide (InSe) have exceptional flexibility. In their paper published in the journal Science, the group describes testing samples of InSe and what they learned about the material. Xiaodong Han with Beijing University of Technology has published a Perspective piece outlining the work by the team in China in the same journal issue.

As the researchers note, most semiconductors are rigid, which means they are difficult to use in applications that require varied surfaces or bending. This has presented a problem for portable device makers as they attempt to respond to user demand for bendable electronics. In this new effort, the researchers in China have found one semiconductor, InSe, that is not only flexible, but is so pliable that it can be processed using rollers.

InSe, as its name implies, is a compound made from indium (a metal element often used in touchscreens) and selenium (a non-metal element). Selenium is also a 2-D semiconductor, and has come under scrutiny after researchers discovered that its bandgap matched the visible region in the electromagnetic spectrum. It has previously been studied for use in specialty optoelectronic applications. In this new effort, the researchers looked into the possibility of using it as a in bendable portable electronic devices.

CES, the world’s largest tech conference, will be online-only in 2021

Posted by in categories: biotech/medical, electronics

The Consumer Electronics Show (CES), long the world’s largest tech trade show, will be all-digital in January 2021, the Consumer Technology Association (CTA) announced on Monday. The CTA cited the COVID-19 pandemic and concerns about the spread of the virus as its reasoning for canceling the in-person event.

CES usually takes place in Las Vegas and involves many large gatherings in tightly packed convention halls, as well as smaller meetings between retailers, manufacturers, and other industry professionals.

Per the CTA, the digital CES will be a “new immersive experience.” The organization did not provide many details about what the online event will look like, but it claims it will be “highly personalized.” The organization still plans to hold CES 2022 in Las Vegas.

New Spin Record Set: 1 Million rpm

Posted by in categories: electronics, energy

Circa 2008

Industrial motors can spin at a head-spinning 250,000 revolutions per minute. But a new matchbook-sized motor runs circles around the competition.

Researchers from ETH Zurich’s Department of Power Electronics created a drive system in cooperation with its industrial partners that exceeded 1,000,000 rpm in tests.

ChipScope – a new approach to optical microscopy

Posted by in category: electronics

For half a millennium, people have tried to enhance human vision by technical means. While the human eye is capable of recognizing features over a wide range of size, it reaches its limits when peering at objects over giant distances or in the micro- and nanoworld. Researchers of the EU funded project ChipScope are now developing a completely new strategy towards optical microscopy.

The conventional light microscope, still standard equipment in laboratories, underlies the fundamental laws of optics. Thus, resolution is limited by diffraction to the so called Abbe limit’ – structural features smaller than a minimum of 200 nm cannot be resolved by this kind of microscope.

So far, all technologies for going beyond the Abbe limit rely on complex setups, with bulky components and advanced laboratory infrastructure. Even a conventional light microscope, in most configurations, is not suitable as a mobile gadget to do research out in the field or in . In the ChipScope project funded by the EU, a completely new strategy towards optical microscopy is explored. In classical the analyzed sample area is illuminated simultaneously, collecting the light which is scattered from each point with an area-selective detector, e.g. the human eye or the sensor of a camera.
