New conductive, cotton-based fiber developed for smart textiles

Posted by in categories: materials, wearables

A single strand of fiber developed at Washington State University has the flexibility of cotton and the electric conductivity of a polymer, called polyaniline.

The newly developed material showed good potential for wearable e-textiles. The WSU researchers tested the fibers with a system that powered an LED light and another that sensed ammonia gas, detailing their findings in the journal Carbohydrate Polymers.

“We have one fiber in two sections: one section is the conventional cotton: flexible and strong enough for everyday use, and the other side is the ,” said Hang Liu, WSU textile researcher and the study’s corresponding author. “The cotton can support the conductive material which can provide the needed function.”

Long in the Bluetooth: Scientists develop a more Efficient way to Transmit Data between Our Devices

Posted by in categories: mobile phones, wearables

University of Sussex researchers have developed a more energy-efficient alternative to transmit data that could potentially replace Bluetooth in mobile phones and other tech devices. With more and more of us owning smart phones and wearable tech, researchers at the University of Sussex have found a more efficient way of connecting our devices and improving battery life. Applied to wearable devices, it could even see us unlocking doors by touch or exchanging phone numbers by shaking hands.

Professor Robert Prance and Professor Daniel Roggen, of the University of Sussex, have developed the use of electric waves, rather than electromagnetic waves, for a low-power way to transmit data at close range, while maintaining the high throughput needed for multimedia applications.

Bluetooth, Wifi, and 5G currently rely on electromagnetic modulation, a form of wireless technology which was developed over 125 years ago.

Enhancing supercapacitor performance through design optimization of laser-induced graphene and MWCNT coatings for flexible and portable energy storage

Posted by in categories: energy, nanotechnology, wearables

The field of supercapacitors consistently focuses on research and challenges to improve energy efficiency, capacitance, flexibility, and stability. Low-cost laser-induced graphene (LIG) offers a promising alternative to commercially available graphene for next-generation wearable and portable devices, thanks to its remarkable specific surface area, excellent mechanical flexibility, and exceptional electrical properties. We report on the development of LIG-based flexible supercapacitors with optimized geometries, which demonstrate high capacitance and energy density while maintaining flexibility and stability. Three-dimensional porous graphene films were synthesized, and devices with optimized parameters were fabricated and tested. One type of device utilized LIG, while two other types were fabricated on LIG by coating multi-walled carbon nanotubes (MWCNT) at varying concentrations.

Team uses gold nanowires to develop wearable sensor that measures two bio-signals

Posted by in categories: biotech/medical, chemistry, information science, nanotechnology, wearables

A research team led by Professor Sei Kwang Hahn and Dr. Tae Yeon Kim from the Department of Materials Science and Engineering at Pohang University of Science and Technology (POSTECH) used gold nanowires to develop an integrated wearable sensor device that effectively measures and processes two bio-signals simultaneously. Their research findings were featured in Advanced Materials.

Wearable devices, available in various forms like attachments and patches, play a pivotal role in detecting physical, chemical, and electrophysiological signals for disease diagnosis and management. Recent strides in research focus on devising wearables capable of measuring multiple bio-signals concurrently.

However, a major challenge has been the disparate materials needed for each signal measurement, leading to interface damage, complex fabrication, and reduced device stability. Additionally, these varied signal analyses require further signal processing systems and algorithms.

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.
