The new microbattery is roughly the size of a gain of dust – less than one square millimeter – and has a minimum energy density of 100 microwatt hours per square centimeter. To achieve this, the team winded up current collectors and electrode strips made of polymeric, metallic, and dielectric materials at the microscale. The researchers used Swiss-roll or micro-origami process.

The layered system with inherent tension is created by consecutively coating thin layers of polymeric, metallic, and dielectric materials onto a wafer surface. The mechanical tension is released by peeling off the thin layers, which then automatically snap back to roll up into a Swiss-Roll architecture to create a self-wound cylinder microbattery. The method is compatible with established chip manufacturing technologies and capable of producing high throughput microbatteries on a wafer surface.

The team behind the world’s smallest battery says it could be used in the human body, where tiny sensors and actuators require a continuous power supply. They also claim that the rechargeable microbatteries could also power the world’s smallest computer chips for about ten hours – for example, to measure the local ambient temperature continuously. In addition, it has great potential in future micro-and nanoelectronic sensorics and actuator technologies, in the Internet of Things, miniaturized medical implants, microrobotic systems, and ultra–flexible electronics.

The heat from Starlink’s receiver dishes is helping felines and other small animals stay warm through the cold winters.

Starlink is an important project of SpaceX and Elon Musk to provide high-speed satellite Internet to mankind. Although it is not yet clear how we humans will benefit, this project is definitely being extremely popular with cats, at least for the time being. The reason is because Starlink’s receiver dishes are becoming the ideal place for cats to rest and warm up in the cold winter.

Specifically, on a Twitter post on New Year’s Eve, one user named Aaron Taylor captured an image of 5 cats cuddled up on one of Starlink satellite dishes. Meanwhile, though the outdoor temperature seemed quite low and the ground was still covered with snow, the heat emitted from the receiver dishes appeared to be enough to warm the kittens, making them continue to lie there.

The-interesting-control method could lead to a hefty fine and jail time.

Eric Schmidt and co-author Graham Allison said in an op-end that 5G development is key as it could enhance a country’s military and intelligence capabilities.

The elixir of technological innovation and the information it delivers at our very fingertips every day has proven to be a Pandora’s Box unleashing misinformation, rumour, hate, selfish malfeasance, and violence. Since when did access to knowledge produce so much havoc? Because that’s what appears to be happening with COVID-19, climate change, and more.

My more recent personal experience is equally relevant. When I got COVID-19 in April 2020, it attacked the lining of my heart temporarily enlarging the upper left chamber where pulmonary veins interact with the muscle. Those veins were damaged by the virus leading to the beginning of changes to my heart rhythm and the onset of atrial fibrillation and other arrhythmias.

Three weeks before getting infected I had a full physical in preparation for upcoming knee replacement surgery. At the time I was told that my heart was healthy with no underlying medical conditions of concern. Then COVID-19 struck leading me to go to the hospital emergency where I was told that I was in danger of an imminent stroke and was now a heart patient.

The Sun’s solar activity cycle moves into high gear and knocks down 40 Starlink satellites. Peak is 2025. How many more could be impacted?

Increasing solar activity could play havoc with mega-constellations like Starlink in the coming years.

There’s a land rush happening — and it’s not in New York City or Beverly Hills.

Early speculators, professional real estate agents, and celebrities are buying up land that doesn’t even exist in the real world. They are investing in metaverse real estate, a concept mind-boggling to most people.

So, what exactly is the metaverse? Technologists say the metaverse is the next level of the internet. It’s a virtual reality platform where people can play games, connect with friends, attend meetings, and even go to virtual concerts. Ever since Facebook announced it would change its name to Meta and focus on building its own digital world, interest in metaverse real estate skyrocketed.
