Dying crash victim saved by his APPLE WATCH that rang 999 after detecting his hard fall and no body movement

Muhammad Fitri, 24, was knocked off his motorbike by a van in a hit-and-run in Singapore and lost consciousness as he saw the vehicle speeding off.

But his Apple smartwatch kicked into action after detecting his fall and when he remained motionless on the ground.

The watch automatically called the emergency services, as well as his other contacts, Chinese newspaper Lianhe Wanbao reports.

The article mentions "bystanders" who were at the scene, which makes me suspect they would have called 999 had his smartwatch not done so (perhaps they did, and it wasn't mentioned in the article), but nonetheless, the incident shows how the devices can save lives.

Tech experts create wearable material that can generate electricity by capturing energy from body movements
https://techxplore.com/news/2022-04-tec ... icity.html
by Meg Cox, Loughborough University
Clothing that can sense our health, communicate information with others, and generate electricity may soon be hitting the market, thanks to new research by Loughborough University.

Dr. Ishara Dharmasena, of the School of Mechanical, Electrical and Manufacturing Engineering (MEME), and a team of researchers at the University of Moratuwa (Sri Lanka) have developed a new, scalable manufacturing technique to create wearable fabrics embedded with very small power generators known as "Triboelectric Nanogenerators" (TENGs).

The technique, which is detailed in a paper published in ACS Applied Electronic Materials, can turn common textile materials into "energy-generating textiles" using established methods such as yarn coating, dip coating, and screen-printing to apply triboelectrically active solutions.

The wearable TENG-containing fabrics are similar in texture to knitted materials used to make jumpers and t-shirts.

I used Samsung Galaxy Watch Active2 for 4 months and deemed it completely useless, just as I expected. No need for such things, a smartphone is enough.
Global economy doubles in product every 15-20 years. Computer performance at a constant price doubles nowadays every 4 years on average. Livestock-as-food will globally stop being a thing by ~2050 (precision fermentation and more). Human stupidity, pride and depravity are the biggest problems of our world.

Hearing better with skin than ears: Research team develops a sound-sensing skin-attachable acoustic sensor
https://techxplore.com/news/2022-07-ski ... hable.html
by Pohang University of Science & Technology (POSTECH)

"Hey, Siri, how's the weather today?" Voice recognition technology is increasingly prevalent. It is a convenient technology with broad applications. However, to get the most of its intended functions, users must stand near the device and articulate carefully. What if the skin on our bodies could recognize voices without the use of devices?

Professor Kilwon Cho and Dr. Siyoung Lee of the Department of Chemical Engineering, together with Professor Wonkyu Moon and Dr. Junsoo Kim of the Department of Mechanical Engineering at POSTECH have developed a microphone that detects sound by applying polymer materials to microelectro-mechanical systems (MEMS)

The small, thin microphone demonstrates a wider auditory field than human ears, while it can be easily attachable to the skin. This academic achievement was recently presented in Advanced Materials.

The conventional MEMS-based microphones used in cellular phones, Bluetooth devices, and others consist of thin, small and sophisticated diaphragm structures. As they are made of rigid, brittle silicon, however, it is difficult to bend the diaphragm or microphone as desired, which interferes with the sound detection ability of the device.

Accelerating tactile communication with skin-attached telehaptics
https://techxplore.com/news/2022-12-tac ... ptics.html
by National Research Council of Science & Technology
Electronics and Telecommunications Research Institute (ETRI) has developed a telehaptic device that remotely transmits tactile sensations in real time by attaching it to the fingertip like a sticker. It is expected to add a sense of immersion to the metaverse and real tactile experience with world-class performance and usability through ultra-miniaturization.

This technology was published in npj Flexible Electronics.
This technology uses the unique vibration pattern of touch and texture. Through tactile collection sensors and tactile reproduction actuators, people can feel textures virtually without touching objects in reality.

Following the disclosure of telehaptic technology in April of last year, ETRI succeeded in advancing the technology into a form that can be adhered to the finger like a sticker.

It solved the large volume and low performance of existing tactile reproduction devices. For a highly immersive user experience, precise tactile and texture reproduction that is thin enough to be attached to the skin is essential.

The research team used a self-developed piezoelectric element and an ultra-thin flexible substrate to precisely integrate microscopic sensors and actuators of less than 1mm on the substrate. The substrate is thin and bendable with a thickness of 1/20 of a human hair (about 4μm), so it is suitable for attaching to the skin.

Will smell trolls be a thing? They would trick you into accepting a smell that is beyond worse than shit and you can't forget it for a while after? :?
To know is essentially the same as not knowing. The only thing that occurs is the rearrangement of atoms in your brain.

Super-stretchable OLED opens door for range of wearable electronics
By Paul McClure
April 17, 2023
https://newatlas.com/electronics/stretc ... ectronics/
Researchers have developed a new OLED display that can be stretched to more than twice its length while still maintaining light emission and a clear image. The development opens the door to a wide range of wearable electronics.

An organic light-emitting diode (OLED) contains thin, flexible sheets of small organic molecules that emit light in response to an electric current. OLEDs are more energy efficient than older LED and LCD displays and are used to make TV and computer screens, and displays for smartphones and handheld gaming consoles.

Following decades of development, OLEDs have become one of the most advanced electroluminescent technologies. But researchers are always looking for new uses. With their low voltage, high efficiency and brightness, and low price, OLEDs are the perfect technology for integration into wearable and implantable devices. But they need some tweaking to improve their softness and stretchability.

Enter researchers from the University of Chicago, who’ve tackled the tight chemical bonds and stiffness of current OLEDs to develop an entirely new, more stretchable alternative.

“The materials currently used in these state-of-the-art OLED displays are very brittle; they don’t have any stretchability,” said Sihong Wang, co-corresponding author of the study. “Our goal was to create something that maintained the electroluminescence of OLED but with stretchable polymers.”

With their background in molecular engineering, the researchers knew that developing a stretchier OLED would require some molecular manipulation. Using computational predictions to develop their new OLED polymers and testing several prototypes, the researchers struck upon a winner with thermally activated delayed fluorescence (TADF), a highly efficient way of allowing organic material to convert electricity into light.

By embedding alkyls – organic chemicals that contain only carbon and hydrogen atoms arranged in chains – in the polymer between TADF units, softness and flexibility were enhanced. The newly designed OLED could be stretched to more than twice its original length without disrupting its light-emitting abilities or display of a clear image.
