Tiny Thermoelectric Device Restores Thermal Perception in Phantom Limb

Summary: Researchers created a revolutionary tiny and efficient thermoelectric device, which can help amputees feel temperature with their phantom limbs.

Known as the wearable thin-film thermoelectric cooler (TFTEC), this device is lightweight, incredibly fast, and energy-efficient, potentially revolutionizing applications such as prosthetics, augmented reality haptics, and thermally-modulated therapeutics. Additionally, this technology has potential in industries like electronics cooling and energy harvesting in satellites.

The study conducted to test the TFTEC demonstrated its ability to elicit cooling sensations in phantom limbs, doing so significantly faster, with more intensity, and less energy than traditional thermoelectric technology.

Stretchy color-changing display points to future of wearable screens

Imagine a wearable patch that tracks your vital signs through changes in the color display, or shipping labels that light up to indicate changes in temperature or sterility of food items.

These are among the potential uses for a new flexible display created by UBC researchers and announced recently in ACS Applied Materials & Interfaces.

“This device is capable of fast, realtime and reversible color change,” says researcher Claire Preston, who developed the device as part of her master’s in electrical and computer engineering at UBC. “It can stretch up to 30 percent without losing performance. It uses a color-changing technology that can be used for visual monitoring. And it is relatively cheap to manufacture.”

Wearable Device Predicts Stroke, Saving Crucial Treatment Time

An Israeli startup has developed a wearable device that can predict the likelihood of an imminent stroke through changes in the carotid artery’s blood flow, potentially helping early intervention and preventing disablity.

Strokes are most commonly caused by a clot blocking the essential supply of blood to the brain, and according to the World Health Organization are the second leading cause of death and the leading cause of disability across the globe.

Over 100 million people have experienced a stroke worldwide, with one in four adults experiencing one in their lifetime. And for 50 percent of them, that means some form of lasting disability.

New study challenges conventional understanding of charging process in electrochemical devices

A new study by researchers at the University of Cambridge reveals a surprising discovery that could transform the future of electrochemical devices. The findings offer new opportunities for the development of advanced materials and improved performance in fields such as energy storage, brain-like computing, and bioelectronics.

Electrochemical devices rely on the movement of charged particles, both ions and electrons, to function properly. However, understanding how these charged particles move together has presented a significant challenge, hindering progress in creating new materials for these devices.

In the rapidly evolving field of bioelectronics, soft conductive materials known as conjugated polymers are used for developing that can be used outside of traditional clinical settings. For example, this type of materials can be used to make wearable sensors that monitor patients’ health remotely or implantable devices that actively treat disease.

Wearable Sensors that Detect Gas Leaks

Gas accidents such as toxic gas leakage in factories, carbon monoxide leakage of boilers, or toxic gas suffocation during manhole cleaning continue to claim lives and cause injuries. Developing a sensor that can quickly detect toxic gases or biochemicals is still an important issue in public health, environmental monitoring, and military sectors. Recently, a research team at POSTECH has developed an inexpensive, ultra-compact wearable hologram sensor that immediately notifies the user of volatile gas detection.

Masahiko Inami and his team at the University of Tokyo have developed a wearable multi-armed device called “Jizai Arms”, to study social interaction among users of robotic limbs. Controlled remotely, the device has sockets for up to six articulated arms that can be removed and attached. The project seeks to explore how technology can function as an extension of the human body.
