Toilets in Japan Will Use Holographic Technology to Replace Physical Keys

If you have ever gone on a trip to Japan, surely you will know how sophisticated public toilets are there. Even for the people who live there, it is commonplace and has become a standard public toilet.

As technology develops, of course, many are thinking of new ways so that we can use the toilet more easily and safely. One of them is by using holographic technology.

Yes, recently a Japanese company called Murakami Corporation is working to create a sophisticated device that displays holographic buttons that will be used in public toilets.

Of course, this is very useful especially in the midst of a pandemic like this. Because now many are quite afraid to press the button in public toilets and using holographic technology is the solution.

It is known that Murakami is working with Parity Innovations to create a holographic device that can display a virtual button that ‘hovers’ in the air. By using an infra-red sensor, user input will be detected by the sensor.

In addition, the plan is that this technology will not only be used in toilets, but can be used for other things such as ATMs, elevators, and others. Murakami plans to release this technology in 2022.

This Unmanned Combat Drone Can Go Up To Speeds of 2,414 km / h

This Unmanned Combat Drone Can Go Up To Speeds of 2,414 km h

Unmanned combat drones are not new anymore. The reason is that we have often heard of combat drones used for war purposes. But only recently Kelley Aerospace has taken unmanned combat drone technology a step further.

How not, it is known that this combat drone named Arrow can travel at speeds of up to 2,414 kilometers per hour!

The drone also comes with a body made of carbon fiber to keep it light. Besides that, the shape is very minimalist and also sharp, making it able to go very fast.

CEO of Kelley Aerospace, Ian Lim said that Arrow was presented as a UAV drone that focuses on speed but also does not leave other important sectors such as toughness.

“UAVs are better known for their toughness. But not for their speed. So that’s why with the Arrow Supersonic UAV, we can solve the speed problem,” said Ian Lim.

It is stated that currently, the Arrow drone is still in the prototype stage. His party is now trying to present a model with a scale of 1/4 which will later be used as proof of his concept.

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.

This is the Hyperloop, the Future Train That Will Be Faster Than Aircraft

This is the Hyperloop, the Future Train That Will Be Faster Than Aircraft

Hyperloop is a transportation concept that was introduced in 2013. It looks like a train but its speed is claimed to be able to penetrate 1,207 Km/hour.

The person who first introduced this transportation concept was Elon Musk where he explained that the Hyperloop moves by creating a low pressure which allows the capsule to move at very high speeds.

Because it is so fast, the Hyperloop is claimed to be faster than the plane. The concept is like a train put in a giant pipe wherein the train can be humans or goods.

The train, which we think of like the capsule, will later be pulled using a vacuum. So from that the reason why this Hyperloop is very fast.

The capsules in the pipe are designed to float, either by the air cushion method or by magnetic technology. Hyperloop is basically similar to a magnetic levitation (maglev) type train, it’s just that because it is not obstructed by air pressure, the speed is much higher.

Various countries are already interested in implementing hyperloop in the future. Hyperloop Transportation Technologies, for example, announced in 2017 that it would present hyperloops in the US, Slovakia, Abu Dhabi, Czech Republic, India, Brazil, South Korea, and Indonesia.
