Researchers develop a stretchable and efficient wearable thermoelectric energy harvester

Posted by in categories: energy, wearables

Dr. Hyekyoung Choi and Min Ju Yun’s research team from the Energy Conversion Materials Research Center, Korea Electrotechnology Research Institute (KERI), has developed a technology that can increase the flexibility and efficiency of a thermoelectric generator to the world’s highest level by using “mechanical metamaterials” that do not exist in nature. The research results were published in Advanced Energy Materials.

In general, a material shrinks in the vertical direction when it is stretched in the horizontal direction. It is like when you press a rubber ball, it flattens out sideways, and when you pull a rubber band, it stretches tightly.

The amount of transversal elongation divided by the amount of axial compression is Poisson’s ratio. Conversely, mechanical metamaterials, unlike materials in nature, are artificially designed to expand in both the horizontal and vertical directions when it is stretched in the horizontal direction. Metamaterials have a negative Poisson’s ratio.

Glasses use sonar, AI to interpret upper body poses in 3D

Posted by in categories: augmented reality, health, robotics/AI, virtual reality, wearables

Throughout history, sonar’s distinctive “ping” has been used to map oceans, spot enemy submarines and find sunken ships. Today, a variation of that technology – in miniature form, developed by Cornell researchers – is proving a game-changer in wearable body-sensing technology.

PoseSonic is the latest sonar-equipped wearable from Cornell’s Smart Computer Interfaces for Future Interactions (SciFi) lab. It consists of off-the-shelf eyeglasses outfitted with micro sonar that can track the wearer’s upper body movements in 3D through a combination of inaudible soundwaves and artificial intelligence (AI).

With further development, PoseSonic could enhance augmented reality and virtual reality, and track detailed physical and behavioral data for personal health, the researchers said.

The next great health wearable? Earbuds that analyze brain waves and sweat content

Posted by in categories: biotech/medical, health, neuroscience, wearables

A first-of-its-kind flexible sensor turns a pair of earbuds into a device capable of recording brain activity and analyzing sweat, making them useful for diagnosing diseases and health monitoring.

The background: Health monitoring wearables can measure our blood pressure, track our heart rates, and even detect infections before we start to feel sick, helping us take better care of ourselves and potentially even giving us a way to prevent the spread of diseases.

The devices are useless if no one wants to wear them, though, so finding designs that are comfortable and easy to integrate into daily life is key. Because earbuds are already popular, researchers have used them as the basis for health monitoring devices that record brain activity to predict strokes, epileptic seizures, or Parkinson’s disease.

Wearables may save astronauts in space from deadly disorientation

Posted by in categories: space, wearables

They’re called vibrotactors and they vibrate to provide orientation cues.

A number of factors, such as the lack of gravity, changed sensory inputs, and the unique conditions of space travel, can cause disorientation in astronauts. This phenomenon is so severe that it can even be deadly to the space dwellers.

A new path for safer space travel

New batteries for electric cars and wearables, backed by multi-million US$ funding, are both fire resistant and flexible

Posted by in categories: climatology, computing, sustainability, wearables

Batteries are regarded as crucial technologies in the battle against climate change, particularly for electric vehicles and storing energy from renewable sources. Anthro Energy’s novel flexible batteries are presently available to wearable manufacturers and could be employed in a variety of areas, including electric cars and laptops.

The innovative batteries score well in fire safety, thanks to new materials and design features that eliminate internal and external mechanical safety risks like explosions. Many of today’s batteries, such as lithium-ion batteries, contain a flammable liquid as an electrolyte.

Anthro Energy’s David Mackaniac and his team have created a flexible polymer electrolyte that is malleable like rubber. The new technology provides increased design flexibility for use across a range of devices, with adaptable shapes and sizes to suit specific applications.

Wearable devices may prevent astronauts getting ‘lost’ in space

Posted by in categories: space travel, wearables

The sky is no longer the limit—but taking flight is dangerous. In leaving the Earth’s surface, we lose many of the cues we need to orient ourselves, and that spatial disorientation can be deadly. Astronauts normally need intensive training to protect against it. But scientists have now found that wearable devices which vibrate to give orientation cues may boost the efficacy of this training significantly, making spaceflight slightly safer.

“Long-duration will cause many physiological and psychological stressors, which will make very susceptible to ,” said Dr. Vivekanand P. Vimal of Brandeis University in the United States, lead author of an article in Frontiers in Physiology on this topic. “When disoriented, an astronaut will no longer be able to rely on their own internal sensors, which they have depended on for their whole lives.”

The researchers used and a multi-axis rotation device to test their vibrotactors in simulated spaceflight, so the senses participants would normally rely on were useless. Could the vibrotactors correct the misleading cues the participants would receive from their vestibular systems, and could participants be trained to trust them?

Google research: Noise-cancelling hearables that track heart rate

Posted by in categories: health, wearables

Google’s new technique works by sending low-intensity ultrasonic probing signals via the speakers.

Researchers at Google have devised a technology that allows active noise-canceling (ANC) wearables to feature health-sensing applications.

The team utilized a technique called audio plethysmography (APG) in ANC wearables to monitor a user’s physiological data, such as heart rate and heart rate variability, without the need for additional sensors or sacrificing battery life.
