Recent technological advances have enabled the development of increasingly compact and flexible devices. This includes wearable or portable technology, such as smart watches, earphones or other smart accessories, which can assist human users in a variety of ways.

Researchers at University of California, Los Angeles (UCLA) have recently devised a strategy that could enable the fabrication of portable, compact and flexible electrocaloric cooling devices. This strategy, outlined in a paper published in Nature Energy, is based on a four-layer cascade mechanism that enables a significant temperature lift in a user’s surroundings.

“Our research started more than five years ago, when we were funded by ARPA-E, an agency of the U.S. department of energy, to solve a key cooling need: to maintain sufficient personal thermal comfort while reducing the HVAC energy consumption for offices and buildings,” Qibing Pei, one of the researchers who carried out the study, told TechXplore. “Our key goal was to create a wearable cooler.”

With lithium-containing batteries facing constraints on many of the metals they contain, Nina Notman looks at whether its group 1 neighbour sodium can supply the answer.

The lithium-ion battery powers much of our modern lives, a fact reflected in this year’s Nobel prize. It resides in devices ranging from very small wearable electronics, through mobile phones and laptops, to electric vehicles and ‘the world’s biggest battery’ – the huge 100MW/129MWh Tesla battery installed on an Australian wind farm in 2017.

‘Lithium-ion has a massive span of applications,’ explains Jonathan Knott, an energy storage researcher at the University of Wollongong in Australia. ‘It is being used as a hammer to crack every nut and we need to start getting a little bit more sophisticated in the use of the best tool for the job.’

The quiet shift in strategy, which brings the Vision Fund’s approach closer to that of a traditional venture capital investor, may ease concerns over big, bold bets going sour, a factor that has left a major gap between SoftBank’s market capitalization and the sum of its investments.

TOKYO — SoftBank Group’s Vision Fund is turning to a new strategy as a global pandemic and government stimulus distort tech valuations: Invest smaller in hopes for bigger returns.

After raising nearly $100 billion and investing $85 billion in high-profile companies like Uber Technologies, WeWork and ByteDance over three years, the Vision Fund is now focusing on making smaller bets in early-stage startups.

Researchers at the University of Colorado Boulder are developing a wearable electronic device that’s “really wearable”—a stretchy and fully-recyclable circuit board that’s inspired by, and sticks onto, human skin.

The team, led by Jianliang Xiao and Wei Zhang, describes its new “electronic skin” in a paper published today in the journal Science Advances. The device can heal itself, much like real skin. It also reliably performs a range of sensory tasks, from measuring the body temperature of users to tracking their daily step counts.

And it’s reconfigurable, meaning that the device can be shaped to fit anywhere on your body.

Real-time health monitoring and sensing abilities of robots require soft electronics, but a challenge of using such materials lie in their reliability. Unlike rigid devices, being elastic and pliable makes their performance less repeatable. The variation in reliability is known as hysteresis.

Guided by the theory of contact mechanics, a team of researchers from the National University of Singapore (NUS) came up with a new sensor material that has significantly less hysteresis. This ability enables more accurate wearable health technology and robotic sensing.

The research team, led by Assistant Professor Benjamin Tee from the Institute for Health Innovation & Technology at NUS, published their results in the prestigious journal Proceedings of the National Academy of Sciences on 28 September 2020.

Swiss researchers are getting excited about a polymer that could allow them to incorporate a “flexible solar concentrator” in textile fibres, making it possible to charge personal electronic devices from the clothes their owners wear.

Over the past few decades, technological advances have enabled the development of increasingly sophisticated, immersive and realistic video games. One of the most noteworthy among these advances is virtual reality (VR), which allows users to experience games or other simulated environments as if they were actually navigating them, via the use of electronic wearable devices.

Most existing VR systems primarily focus on the sense of vision, using headsets that allow users to see what is happening in a game or in another simulated environment right before their eyes, rather than on a screen placed in front of them. While this can lead to highly engaging visual experiences, these experiences are not always matched by other types of sensory inputs.

Researchers at Nagoya University’s School of Informatics in Japan have recently created a new VR game that integrates immersive audiovisual experiences with tactile perception. This game, presented in a paper published in the Journal of Robotics, Networking and Artificial Life, uses a player’s biometric data to create a spherical object in the VR space that beats in alignment with his/her heart. The player can thus perceive the beating of his/her heart via this object visually, auditorily and tactually.
