Nanotech OLED electrode liberates 20% more light, could slash display power consumption
https://phys.org/news/2021-06-nanotech- ... slash.html
by University of Michigan

A new electrode that could free up 20% more light from organic light-emitting diodes has been developed at the University of Michigan. It could help extend the battery life of smartphones and laptops, or make next-gen televisions and displays much more energy efficient.

The approach prevents light from being trapped in the light-emitting part of an OLED, enabling OLEDs to maintain brightness while using less power. In addition, the electrode is easy to fit into existing processes for making OLED displays and light fixtures.

"With our approach, you can do it all in the same vacuum chamber," said L. Jay Guo, U-M professor of electrical and computer engineering and corresponding author of the study.

Unless engineers take action, about 80% of the light produced by an OLED gets trapped inside the device. It does this due to an effect known as waveguiding. Essentially, the light rays that don't come out of the device at an angle close to perpendicular get reflected back and guided sideways through the device. They end up lost inside the OLED.

Jigsaw Puzzle Lights Up With Each Piece
Putting the last piece of a project together and finally finishing it up is a satisfying feeling. When the last piece of a puzzle like that is a literal puzzle, though, it’s even better. [Nadieh] has been working on this jigsaw puzzle that displays a fireworks-like effect whenever a piece is placed correctly, using a lot of familiar electronics and some unique, well-polished design.

The puzzle is a hexagonal shape and based on a hexagonally symmetric spirograph, with the puzzle board placed into an enclosure which houses all of the electronics. Each puzzle piece has a piece of copper embedded in a unique location so when it is placed on the board, the device can tell if it was placed properly or not. If it was, an array of color LEDs mounted beneath a translucent diffuser creates a lighting effect that branches across the entire board like an explosion. The large number of pieces requires a multiplexer for the microcontroller, an ATtiny3216.

New electronic paper displays brilliant colours
Imagine sitting out in the sun, reading a digital screen as thin as paper, but seeing the same image quality as if you were indoors. Thanks to research from Chalmers University of Technology, Sweden, it could soon be a reality. A new type of reflective screen – sometimes described as ‘electronic paper’ – offers optimal colour display, while using ambient light to keep energy consumption to a minimum.
Traditional digital screens use a backlight to illuminate the text or images displayed upon them. This is fine indoors, but we’ve all experienced the difficulties of viewing such screens in bright sunshine. Reflective screens, however, attempt to use the ambient light, mimicking the way our eyes respond to natural paper.
“For reflective screens to compete with the energy-intensive digital screens that we use today, images and colours must be reproduced with the same high quality. That will be the real breakthrough. Our research now shows how the technology can be optimised, making it attractive for commercial use,” says Marika Gugole, Doctoral Student at the Department of Chemistry and Chemical Engineering at Chalmers University of Technology.

In 2030, You Won't Own Any Gadgets
7/06/21

Owning things used to be simple. You went to the store. You paid money for something, whether it be a TV, clothes, books, toys, or electronics. You took your item home, and once you paid it off, that thing belonged to you. It was yours. You could do whatever you wanted with it. That’s not how it is today, and by 2030, technology will have advanced to the point that even the idea of owning objects might be obsolete.

Many a think piece has been written about how Millennials aren’t as interested in owning things as their predecessors. After decades of Boomers keeping up with the Joneses, Millennials were supposedly “more about the experience” than physical goods. There’s a kernel of truth in that, but the shift to services was telegraphed a long time ago.

Back in 2016, the World Economic Forum released a Facebook video with eight predictions it had for the world in 2030. “You’ll own nothing. And you’ll be happy,” it says. “Whatever you want, you’ll rent. And it’ll be delivered by drone.”

“Everything you considered a product, has now become a service,” reads another WEF essay published on Forbes. “We have access to transportation, accommodation, food, and all the things we need in our daily lives. One by one all these things became free, so it ended up not making sense for us to own much.”

The WEF’s framing is overly optimistic, but this is the future we’re rapidly hurtling toward. I rent my apartment, and therefore, all the home appliances in it. If I wanted, I could rent all my furniture and clothes. Sure, I have my own computer and phone, but there are plenty of people who use company-issued gadgets. And if I didn’t want company-issued items, I could always rely on electronics rentals. I like cooking and grocery shopping, but I could just sign up for a meal kit service and call it a day. I wouldn’t even need appliances like toasters, rice cookers, blenders, air fryers, or anything beyond a microwave. To get around, there are Citi Bikes, Uber, and Zipcar.

While the fabrics we wear today might keep us warm and protect us from the elements, scientists continue to demonstrate how they might soon do far more than that. MIT scientist Yoel Fink has been at the cutting edge of this field for more than a decade and has just made a significant breakthrough, demonstrating the first ever digital fabric-fiber that can store and process information, among other some other exciting functions.

From stretchable fabrics that power wearables with sweat, to shirts that harvest energy from movement, and weavable LED fibers that could form wearable displays, the field of smart textiles is one brimming with exciting possibilities. Fink and his colleagues demonstrated an interesting one way back in 2010, developing fibers that detect sound and can be woven into fabric to turn it into a sensitive microphone.

Fink's team has now broken further ground in this area. They describe the electronic fibers that have been developed so far as analog, in that they can carry a continuous electrical signal but not digital information, which would be processed in 0s and 1s. To bring this kind of capability to textile fibers, the MIT team had to get creative.
We are really living now in a world full of collecting data even our fabrics! Privacy nows pays a lot.

they can f*ck right off with that. I get the appeal of mobility that allows you to literally not have to drag around an anchor of everything you own, which starts to feel like your things own you... but monthly rental or lease payments for literally everything? 20$ for a cheap microwave, once and you own it... or 3$ a month for for indefinite time? by five years in you have paid 9x as much for the same usage and you have no resell rights.

Thats just a small sample. Washer and drier, dishes, silverware, chairs, beds, fridges, ovens. etc.

this is just another form of money extraction in excess of the value of the life given to the people renting. and the likelyhood of substandard used goods having defects, or in the case of furniture, things like bedbugs.

and logistically it's ripe for a bunch of hidden charges, micro transactions ect.

For the past 10 years, Sonia Grego has been thinking about toilets – and more specifically what we deposit into them. “We are laser-focused on the analysis of stool,” says the Duke University research professor, with all the unselfconsciousness of someone used to talking about bodily functions. “We think there is an incredible untapped opportunity for health data. And this information is not tapped because of the universal aversion to having anything to do with your stool.”

As the co-founder of Coprata, Grego is working on a toilet that uses sensors and artificial intelligence to analyse waste; she hopes to have an early model for a pilot study ready within nine months. “The toilet that you have in your home has not functionally changed in its design since it was first introduced,” she says, in the second half of the 19th century. There are, of course, now loos with genital-washing capabilities, or heated seats, but this is basic compared with what Grego is envisaging. “All other aspects of your life – your electricity, your communication, even your doorbell – have enhanced capabilities.”

The smart toilet’s time has come and it is a potentially huge market – in the developed world, everyone who is able to uses a toilet multiple times a day. Grego adds that she can “certainly envision a world” in which a toilet that does more than flush excreta “is available to every household”. There are numerous companies working on bringing that to market – a race to the bottom, if you will.

The rumors were true. Amazon is working on an Alexa-powered robot on wheels. At its fall hardware event, the company showed off Astro. Set to initially cost $1,000 when it becomes available later this year, it's essentially an Alexa display that can roam around your home.

The robot features a periscope camera that allows it to expand its field of view beyond floor level. It can extend that camera to check on things like stovetops and sleeping pets. With Ring's Protect Pro subscription service, you can also program Astro to patrol your home while you're away. It can detect the sound of a smoke alarm, carbon monoxide detector or breaking glass. It will send you notifications when it notices something usual, and you can save what it records to your Ring account.

Just a game? Study shows no evidence that violent video games lead to real-life violence

5 Nov 2021

Mass media and general public often link violent video games to real-life violence, although there is limited evidence to support the link.

Debate on the topic generally intensifies after mass public shootings, with some commentators linking these violent acts to the perpetrators’ interests in violent video games.

However, others have pointed out that different factors, such as mental health issues and/or easy access to guns, are more likely explanations.

In the light of these conflicting claims, President Obama called in 2013 for more government funding for research on video games and violence.

But before governments introduce any policies restricting access to violent video games, it is important to establish whether violent video games do indeed make players behave violently in the real world.
