Transparent electronic devices could have numerous valuable real-world applications. Among other things, they could enable the creation of new optical devices, smart gear or wearables, invisible solar panels and integrated communication systems.

Researchers at Xidian University, Southeast University and Wuhan University of Technology recently developed new, highly promising, transparent metadevices based on quasi-one-dimensional surface plasmon polariton (quasi-1D SPP) structures. These devices, introduced in a paper published in Nature Electronics, could be used to develop optically and radiofrequency transparent wireless communication systems and other promising technologies.

“Transparent and invisible electronic device is a fascinating goal that scientists and engineers are enthusiastically pursuing,” Prof. Bian Wu, one of the researchers who carried out the study, told Tech Xplore. “Currently, transparent electronics typically rely on the intrinsic properties of optically conductive materials, which are not radiofrequency transparent and have low operating efficiency. SSPs can be used to concentrate, channel and enhance energy. However, the use of SPPs in the development of optical and radiofrequency transparency remains blank.”

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.

Breakthrough research represents “the missing link that will enable wearables to control genes in the not-so-distant future,” researchers say.

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.
