Super-adhesive patches can adapt to different motions for enhanced skin interaction

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

A research team affiliated with UNIST has unveiled an ultra-strong adhesive patch platform that adheres effectively to rough skin surfaces and shows remarkable motion adaptiveness during dynamic body movements, all while offering irritation-free removal on demand. The key to this technology lies in the surface adaptability inspired by barnacles and armadillo carapaces, which feature a tessellated structure that balances rigidity and flexibility.

The team, led by Professor Hoon Eui Jeong from the Department of Mechanical Engineering and Professor Jae Joon Kim from the Department of Electrical Engineering at UNIST, along with researchers from the National Institute of Ecology (NIE), has introduced a highly adhesive, detachable, and stretchable skin patch, known as the Motion Adaptive Tessellation Patch.

This innovative technology is garnering attention for its potential to facilitate the commercialization of wearable electronic devices, such as health care monitoring systems and transdermal drug delivery systems. The research is published in the journal Advanced Materials.

Breakthrough Material Perfectly Absorbs All Electromagnetic Waves

Posted by in categories: mobile phones, robotics/AI, wearables

A new composite material developed by KIMS researchers absorbs over 99% of electromagnetic waves from different frequencies, improving the performance of devices like smartphones and wearables.

A team of scientists from the Korea Institute of Materials Science (KIMS) has developed the world’s first ultra-thin film composite material capable of absorbing over 99% of electromagnetic waves from various frequency bands, including 5G/6G, WiFi, and autonomous driving radar, using a single material.

This novel electromagnetic wave absorption and shielding material is less than 0.5mm thick and is characterized by its low reflectance of less than 1% and high absorbance of over 99% across three different frequency bands.

Seatbelt-integrated biosensor could reliably track the alertness and stress of pilots and drivers

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

Over the past decades, electronics and biomedical engineers have developed increasingly sophisticated biosensors, devices that can pick up biological signals from human users. These sensors, which are generally embedded in wearable or implantable technologies, often do not perform as well in settings where users are moving a lot, such as within a vehicle.

Researchers at the National University of Singapore and Tsinghua University have recently developed a new sensor that can pick up and track biological signals, such as the heartbeat and respiration, without being in contact with the body of users. This sensor, presented in a paper published in Nature Electronics, could be used to pick up the cardiopulmonary signals of humans while they are in dynamic and closed environments, such as a plane cabin, a moving car or a bus.

“Monitoring drivers’ alertness or stress is essential for ,” Xi Tian, co-author of the paper, told Tech Xplore. “Existing designed to measure physiological markers of fatigue, such as heart rate and respiration, face challenges in moving vehicles due to the unpredictable vibrational noise. To overcome these challenges, our research focused on developing an automotive biosensor capable of non-contact and reliable health monitoring in dynamic environments.”

Move Over Plastics: Revolutionary Soft, Sustainable Material Set To Transform Medical Devices and Wearable Tech

Posted by in categories: biotech/medical, computing, nanotechnology, wearables

Step aside, hard and rigid materials — a new soft, sustainable electroactive material is here, ready to unlock new possibilities for medical devices, wearable technology, and human-computer interfaces.

Using peptides and a snippet of the large molecules in plastics, Northwestern University materials scientists have developed materials made of tiny, flexible nano-sized ribbons that can be charged just like a battery to store energy or record digital information. Highly energy efficient, biocompatible, and made from sustainable materials, the systems could give rise to new types of ultralight electronic devices while reducing the environmental impact of electronic manufacturing and disposal.

The study was recently published in the journal Nature.

Artificial magnetic muscles can support tensile stresses up to 1,000 times their own weight

Posted by in categories: biotech/medical, cyborgs, robotics/AI, wearables

A research team, led by Professor Hoon Eui Jeong from the Department of Mechanical Engineering at UNIST has introduced an innovative magnetic composite artificial muscle, showcasing an impressive ability to withstand loads comparable to those of automobiles. This material achieves a stiffness enhancement of more than 2,700 times compared to conventional systems. The study is published in Nature Communications.

Soft artificial muscles, which emulate the fluidity of human muscular motion, have emerged as vital technologies in various fields, including robotics, wearable devices, and . Their inherent flexibility allows for smoother operations; however, traditional materials typically exhibit limitations in rigidity, hindering their ability to lift substantial weights and maintain precise control due to unwanted vibrations.

To overcome these challenges, researchers have employed variable rigid materials that can transition between hard and soft states. Yet, the available range for stiffness modulation has remained constrained, along with inadequate mechanical performance.

New Discovery Paves The Way to Generating Energy From Body Heat

Posted by in categories: biotech/medical, wearables

If you’ve ever seen yourself through a thermal imaging camera, you’ll know that your body produces lots of heat. This is in fact a waste product of our metabolism. Every square foot of the human body gives off heat equivalent to about 19 matches per hour.

Unfortunately, much of this heat simply escapes into the atmosphere. Wouldn’t it be great if we could harness it to produce energy? My research has shown this would indeed be possible. My colleagues and I are discovering ways of capturing and storing body heat for energy generation, using eco-friendly materials.
