This Researcher Successfully Created 'Smart Tattoo', Can Emit Light

Scientists have created a ‘smart tattoo’ that can be applied to human skin and shine. These tattoos rely on the same light-emitting technology found on everything from TVs and smartphone screens.

However, they can be applied in the same way as a temporary tattoo, placed on paper, and then transferred to a person’s skin. That technology can be used to make an athlete’s skin glow if they need to drink water. The tattoo can also light up as a warning if a person is exposed to the sun. They can also be applied to objects, such as food, which can signal when they have passed their expiration date.

But it is not only needed to be worn functionally, and glowing tattoos can also be used for fashion. Seeing this, a researcher from University College London, Franco Cacialli, gave his comments.

“The tattooable OLED we’re showing you for the first time can be made on a large scale and very cheaply. They can be combined with other forms of electronic tattooing for a very wide range of uses, ”says Franco Cacialli.

“This could be for fashion – for example, providing glowing tattoos and light-emitting nails. In sports, they can be combined with a sweat sensor to signal dehydration. “, he continued.

“In health care, they can emit light when a patient’s condition changes – or, if the tattoos are changed towards the skin, they could potentially be combined with light-sensitive therapy to target cancer cells, for example,” he said.

“Our proof-of-concept study is the first step. Future challenges will include encapsulating the OLED as much as possible to stop it from deteriorating quickly through contact with air, as well as integrating the device with a battery or supercapacitor. “He concluded.

However, this will not be the first time engineers have built new technology into tattoos. This statement was made by the senior author and a researcher at the Italian Institute of Technology, Virgilio Mattoli.

“At the Italian Institute of Technology, we have previously pioneered electrodes that we have tattooed onto people’s skin which can be used to perform diagnostic tests such as an electrocardiogram,” said Virgilio Mattoli.

“The advantage of this technology is that it is cheap, easy to apply and use, and is easy to wash with soap and water.” he continued.

The new study saw researchers build OLED devices just 2.3 micrometers thick, less than 400 millimeters, or one-third the length of a blood cell. It consists of an electroluminescent polymer, which ignites when an electric field is applied, which is then placed on an insulating layer and standard tattoo paper.

China Launches World’s First Glass Cable Car, Gives Passengers Beautiful Views

China Launches World's First Glass Cable Car, Gives Passengers Beautiful Views

China has debuted its first glass-bottomed sky train, which will allow passengers to see 270-degree views of the country’s beautiful landscape.

According to a report on CNN, adapted on Wednesday (7/7/2021), the glass-bottomed sky train, which resembles the country’s most popular animal – Panda, was launched from the production line from Chengdu, Sichuan Province on June 26.

The train runs on renewable energy and can travel at a speed of 80 km/h. The train is part of the Dayi Air-rail project, which includes China’s first renewable energy suspension rail demonstration track.

According to Global News, reported on Wednesday (7/7/2021), the new energy aerial rail refers to a cable car driven by a lithium battery power pack.

Maximum 120 people can fit in each car. Given the fact that glass can reflect heat, the train is air-conditioned to balance it. It is made of lightweight carbon fiber material. Unlike the subway or light rail, the air-rail project combines tourist traffic and sightseeing features.

The Dayi Railway, with a distance of about 11.5 kilometers, has four stations connecting several important tourist points. The project is being developed by Zhongtang Air Rail Technology. They are targeting construction to be completed by the end of this year.

“The new generation of vehicles weighs about 2.5 tons, is 0.5 tons lighter than traditional ones, and has the lowest self-weight coefficient in the industry,” Zhong Min, deputy general director of Zhongtang Air Rail.

This YouTuber Builds a Mini PC That Can Run the macOS Big Sur Operating System

Running the macOS operating system on PC devices has become a common thing, but what happens if the operating system is run on a mini PC with not too high specifications? Of course, that’s a pretty interesting thing.

Recently a YouTuber named Ike T. Sanglay or Iketsj has uploaded a video where he tries to assemble a PC device that will later run Apple’s macOS.

Initially, Iketsj used the LattePanda Alpha SBC board which was then equipped with an Intel Core M3, 8GB RAM, 240GB SSD, and was also connected to an Arduio Leonardo.

The process of making the casing is also shown where Iketsj made it using a 3D printer. The results of the case can be said to be quite good where he can include all components such as the board, screen, and keyboard in a size that is not too large.

Although the process of installing macOS Big Sur (Hackintosh) on the device is not shown, at least Iketsj shows how the macOS can be used smoothly.

In the video, Iketsj says that it costs more to assemble the device than buying a Mac Mini from Apple. But Iketsj wants to do something challenging and doesn’t want to buy a ready-made device.

Future Closer, Archer Officially Launches Flying Taxi Tak

Archer Aviation officially launched its first electric flying taxi called “Maker”. It is shaped like a helicopter and is claimed to be zero emissions because it is operated using batteries.

Reported by Reuters , Sunday (13/6/2021), Archer’s debut was staged in a hangar using XR technology to simulate travel.

Archer Aviation’s flying taxis cannot be flown commercially. However, the shows and simulations have opened many people’s horizons about the future.

Future Closer, Archer Officially Launches Flying Taxi Tak

Archer hopes that Maker’s flying taxi can be launched commercially by 2024. Currently, they are in the process of certifying the four-passenger aircraft.

“Our real goal is to create mass market transportation solutions in and around cities,” said co-founder and co-CEO Brett Adcock.

This flying taxi can glide at a speed of 150 miles per hour (240 km per hour) for a distance of up to 60 miles (100 km). The price is US$3-US$4 per mile for one passenger.

For example, a 17-mile trip will cost US$50-US$70 with a travel time of 7 minutes. This is much faster than a car ride which takes 60-90 minutes.

However, experts predict the multibillion-dollar eVTOL market will not immediately generate money and the timing of approval is uncertain.
