Wearable electronic devices are playing a rapidly expanding role in the acquisition of individuals’ health data for personalized medical interventions; however, wearables cannot yet directly program gene-based therapies because of the lack of a direct electrogenetic interface. Here we provide the missing link by developing an electrogenetic interface that we call direct current (DC)-actuated regulation technology (DART), which enables electrode-mediated, time-and voltage-dependent transgene expression in human cells using DC from batteries. DART utilizes a DC supply to generate non-toxic levels of reactive oxygen species that act via a biosensor to reversibly fine-tune synthetic promoters.

New breakthrough in material design will help football players, car occupants, and hospital patients.

A significant breakthrough in the field of protective gear has been made with the discovery that football players were unknowingly acquiring permanent brain damage from repeated head impacts throughout their professional careers. This realization triggered an urgent search for better head protection solutions. Among these innovations is nanofoam, a material found inside football helmets.

Thanks to mechanical and aerospace engineering associate professor Baoxing Xu at the University of Virginia and his research team, nanofoam just received a big upgrade and protective sports equipment could, too. This newly invented design integrates nanofoam with “non-wetting ionized liquid,” a form of water that Xu and his research team now know blends perfectly with nanofoam to create a liquid cushion. This versatile and responsive material will give better protection to athletes and is promising for use in protecting car occupants and aiding hospital patients using wearable medical devices.

Not surprisingly, the Intelligence Community (IC), Department of Defense (DoD), and first responders at the Department of Homeland Security (DHS) and other agencies are also interested in wearable electronics. With its Smart Electrically Powered and Networked Textile Systems (SMART ePANTS) program, the Intelligence Advanced Research Projects Activity (IARPA) is delivering the largest single investment ever made1 to make Advanced Smart Textiles2 (AST) a reality.

According to SMART ePANTS Program Manager, Dr. Dawson Cagle, developing clothing with sensor systems that can record audio, video, and geolocation data would significantly improve the capabilities of IC, DoD, DHS staff, and others working in dangerous or high-stress environments, such as crime scenes and arms control inspections. Dr. Cagle also asserted that ASTs could collect information one doesn’t notice, which would increase job effectiveness.

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.

In a recent perspective piece published in the Nature Medicine Journal, researchers discussed the current achievements, challenges, and potential opportunities in using digital technologies, such as remote medicine and wearables in geriatric medicine and care.

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.”

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.

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.

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.
