World’s smallest fine particle air pollution sensor fits inside a phone

Posted by in categories: biotech/medical, health, mobile phones, wearables

Air pollution involving very fine dust, such as PM2.5 particles, poses a serious threat to human health. Scientists in Austria have developed what they call the smallest particle sensor in the world, designed specifically to detect these harmful pollutants and offer a highly localized picture of air quality by being integrated into wearables and mobile devices.

According to the World Health Organization, air pollution contributes to more than four million premature deaths each year. While PM10 particles with a diameter of 10 microns or less can also make their way into their lungs, the finer PM2.5 particles are even more dangerous, as they can penetrate the lung barrier, slip into the blood stream and, through chronic exposure, cause severe forms of cardiovascular and respiratory disease, along with other health problems.

Concentrations of PM2.5 particles can be gauged through monitoring stations positioned around cities and regions, in fact the US Environmental Protection Agency uses a nationwide network of these stations to track air quality trends. But scientists from Austria’s Graz University of Technology (TU Graz) have been working on a more cost-effective, compact and versatile solution that can alert individual users of dangerous conditions in real time.

The brain-computer interface is coming, and we are so not ready for it

Posted by in categories: computing, law, neuroscience, physics, wearables

Are you ready?

“if you were the type of geek, growing up, who enjoyed taking apart mechanical things and putting them back together again, who had your own corner of the garage or the basement filled with electronics and parts of electronics that you endlessly reconfigured, who learned to solder before you could ride a bike, your dream job would be at the Intelligent Systems Center of the Applied Physics Laboratory at Johns Hopkins University. Housed in an indistinct, cream-colored building in a part of Maryland where you can still keep a horse in your back yard, the ISC so elevates geekdom that the first thing you see past the receptionist’s desk is a paradise for the kind of person who isn’t just thrilled by gadgets, but who is compelled to understand how they work.”

LG officially announces its battery-powered air purifier mask

Posted by in categories: biotech/medical, wearables

LG has officially announced a portable air purifier that you wear on your face like a mask. The PuriCare Wearable Air Purifier uses a pair of replaceable filters similar to what you’d find in LG’s range of air purifiers for the home, pairing them with battery-powered fans to help you breathe. LG says the device has sensors to detect when you’re breathing in or out, and adjusts the fans’ speeds accordingly.

Today’s announcement ahead of IFA 2020 doesn’t explicitly mention the COVID-19 pandemic, but it heavily implies that the mask was developed in response to it. The company says the wearable air purifier is designed to replace the “inconsistent” homemade masks worn by some people, as well as the disposable masks that it says have been in short supply.

Back in July, when LG first announced the mask and said it would be donating 2,000 of the devices to a university hospital in Seoul, one executive from the company said they hoped it would help medical staff “amid the protracting COVID-19 pandemic,” The Korea Herald reported. They hoped it would make it easier for medical staff to wear a mask for hours at a time.

Scientists Develop Nanophotonic 3D Printing for Virtual Reality Screens

Posted by in categories: 3D printing, government, mobile phones, nanotechnology, quantum physics, virtual reality, wearables

In Korea, scientists are turning to better ways for improving our screen time, and this means 3D printing something most of us know little about: quantum dots. Focusing on refining the wonders of virtual reality and other electronic displays even further, researchers from the Nano Hybrid Technology Research Center of Korea Electrotechnology Research Institute (KERI), a government-funded research institute under National Research Council of Science & Technology (NST) of the Ministry of Science and ICT (MSIT), have created nanophotonic 3D printing technology for screens. Meant to be used with virtual reality, as well as TVs, smartphones, and wearables, high resolution is achieved due to a 3D layout expanding the density and quality of the pixels.

Led by Dr. Jaeyeon Pyo and Dr. Seung Kwon Seol, the team has published the results of their research and development in “3D-Printed Quantum Dot Nanopixels.” While pixels are produced to represent data in many electronics, conventionally they are created with 2D patterning. To overcome limitations in brightness and resolution, the scientists elevated this previously strained technology to the next level with 3D printed quantum dots to be contained within polymer nanowires.

Scientists develop artificial intelligence system for high precision recognition of hand gestures

Posted by in categories: health, robotics/AI, wearables

Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed an Artificial Intelligence (AI) system that recognizes hand gestures by combining skin-like electronics with computer vision.

The recognition of human by AI systems has been a valuable development over the last decade and has been adopted in high-precision surgical robots, health monitoring equipment and in .

AI recognition systems that were initially visual-only have been improved upon by integrating inputs from wearable sensors, an approach known as ‘data fusion’. The wearable sensors recreate the skin’s sensing ability, one of which is known as ‘somatosensory’.

Implantable transmitter provides wireless option for biomedical devices

Posted by in categories: biotech/medical, computing, mobile phones, wearables

Purdue University innovators are working on inventions to use micro-chip technology in implantable devices and other wearable products such as smart watches to improve biomedical devices, including those used to monitor people with glaucoma and heart disease.

The Purdue team developed a fully implantable radio-frequency transmitter chip for wireless sensor nodes and . The research is published in the journal IEEE Transactions on Circuits and Systems II. The transmitter chip consumes lowest amount of energy per digital bit published to date.

The transmitter works in a similar fashion to in mobile phones and , but the Purdue transmitter has an unprecedented level of miniaturization and low-energy consumption that it can be implanted into an eye to monitor pressure for a glaucoma patient or into another part of the body to measure data related to heart functions.

‘Drawn-on-skin’ electronics offer breakthrough in wearable monitors

Posted by in categories: biological, engineering, health, wearables

A team of researchers led by Cunjiang Yu, Bill D. Cook Associate Professor of Mechanical Engineering at the University of Houston, has developed a new form of electronics known as “drawn-on-skin electronics,” allowing multifunctional sensors and circuits to be drawn on the skin with an ink pen.

The advance, the researchers report in Nature Communications, allows for the collection of more precise, motion artifact-free health data, solving the long-standing problem of collecting precise biological data through a when the subject is in motion.

The imprecision may not be important when your FitBit registers 4,000 steps instead of 4,200, but sensors designed to check heart function, temperature and other physical signals must be accurate if they are to be used for diagnostics and treatment.

MIT Dream Research Interacts Directly With an Individual’s Dreaming Brain and Manipulates the Content

Posted by in categories: neuroscience, wearables

Device not only helps record dream reports, but also guides dreams toward particular themes.

The study of dreams has entered the modern era in exciting ways, and researchers from MIT and other institutions have created a community dedicated to advancing the field, lending it legitimacy and expanding further research opportunities.

In a new paper, researchers from the Media Lab’s Fluid Interfaces group introduce a novel method called “Targeted Dream Incubation” (TDI). This protocol, implemented through an app in conjunction with a wearable sleep-tracking sensor device, not only helps record dream reports, but also guides dreams toward particular themes by repeating targeted information at sleep onset, thereby enabling incorporation of this information into dream content. The TDI method and accompanying technology serve as tools for controlled experimentation in dream study, widening avenues for research into how dreams impact emotion, creativity, memory, and beyond.
