2022-07-13 17:00:07 Scientists have created a graphene "tattoo" that will allow you to track blood pressure for a long time and covertly

A team of researchers from the University of Texas at Austin and Texas A&M University have developed a sticky and stretchable graphene electronic "tattoo" that adheres comfortably to the skin and is almost invisible.

The device makes a measurement by applying a weak electric current to the skin, which allows you to measure the resistance of the area of ​​u200bu200bthe body between the sensors.

In total, the researchers collected 18,667 records, of which 89% went to training the neural network and 11% to testing for cross-validation.

The sensor was tested in extreme heat and during physical activity on volunteers, which resulted in heavy sweating. In all cases, the sensor gave accurate readings during continuous operation up to 300 minutes or longer. This is 10 times more than in other sensors. Open / Comment

2022-07-13 13:00:13 Honda introduced the MS01 electric bike. Keyless entry, LCD screen, 65 km range and 25 km/h top speed at $745

400 W motor that accelerates the bike up to 25 km/h. The removable lithium battery provides a range of up to 65 km. The company believes that on average, the battery will have to be charged once or twice a week. The MS01 also provides a keyless entry system and an LCD screen, there is an LED headlight and a lantern.

The novelty is priced at $ 745, there are two color options - white and black. The volume of the first batch will be 5,000 pieces, and nothing is said about whether the MS01 will go on sale in other countries. Open / Comment

2022-07-13 11:00:16 Xiaomi introduced the ultra-budget monitor Redmi Monitor for only $75

Xiaomi launched the new Redmi Monitor 21.5" in China. The device uses a 21.5" VA display. It has 1080P resolution, 75Hz refresh rate, 300 nits brightness, covers 178° wide viewing angle and NTSC 72 color gamut. The contrast ratio of the new Redmi monitor is 3000:1.

HDMI 1.4 and VGA ports are available, with HDMI cable, power adapter, screws and screwdriver included.

But the most important thing about the new Redmi Monitor is its price, which is only $75. It is with this price that it is available in presale in China. Whether the monitor will be released outside the Celestial Empire is unknown. Open / Comment

The Waymo co-founder shared a video on Twitter from San Francisco, California. The video shows how the drone copes with the traffic situation in San Francisco late at night after the baseball game of the local team. Open / Comment

2022-07-12 12:00:16 AT&T puts 5G base stations on drones

The American operator AT&T has developed an unmanned aerial vehicle capable of providing 5G coverage to an area with unstable communications. The device, called 5G Flying COW (from “Cell on Wings” - a cell on the wings), is able to provide reliable signal reception over an area of ​​​​about 26 km², being at an altitude of about 100 m.

There are many possible use cases for such a drone, but AT&T's original idea is to provide first responders with communications where it might be needed urgently. The weakest point of modern drones is limited battery life: professional models can usually stay in the air for up to two hours, while consumer-grade devices rarely draw more than 40 minutes.

2022-07-12 10:00:20 Air taxi Lilium was able to smoothly transition from vertical climb to horizontal flight on wings

The developers of the Lilium air taxi with vertical takeoff and landing reported that the electric aircraft successfully completed the most important maneuver - it smoothly switched from vertical rise on propellers to flight on wings. Without such maneuvers during takeoff and landing, air taxis are unlikely to be successful. Flight over long distances is effective only on wings according to the laws of aerodynamics, and not on voracious channel propellers. Open / Comment

Robots with manipulators can wash dishes, lift objects and clean furniture. Production of these robots will begin by 2030. Open / Comment

2022-06-07 13:47:43 JSK robotics experts at the University of Tokyo have developed a humanoid robot with a unique sweating mechanism.

Kengoro - weighs 56 kg, is built on a 1.7 m high aluminum frame and has 108 electric motors that need to be cooled. To do this, using a 3D printer, they printed parts of the robot's skeleton with microchannels inside, water circulates through them and cools the structure. For one day of work, the robot takes half a glass of deionized water.

Thanks to this system, Kengoro is able to perform intense loads, for example, push up from the floor for 11 minutes in a row without the motors failing due to overheating. Open / Comment
