Researchers have constructed a paper-based device as a model of wearables that can collect, transport, and analyze sweat in next-generation wearable technology. Using a process known as capillary action, akin to water transport in plants, the device uses evaporation to wick fluid that mimics the features of human sweat to a sensor for up to 10 days or longer.
A deep-learning powered single-strained electronic skin sensor can capture human motion from a distance. The single strain sensor placed on the wrist decodes complex five-finger motions in real time with a virtual 3D hand that mirrors the original motions. The deep neural network boosted by rapid situation learning (RSL) ensures stable operation regardless of its position on the surface of the skin.
Researchers have developed biomaterial-based inks that respond to and quantify chemicals released from the body (e.g., in sweat and potentially other biofluids) or in the surrounding environment by changing color. The inks can be screen printed onto textiles such as clothes, shoes, or even face masks in complex patterns and at high resolution, providing a detailed map of human response or exposure.
Researchers at MIT and Brigham and Women’s Hospital have designed a new face mask that they believe could stop viral particles as effectively as N95 masks. Unlike N95 masks, the new masks were designed to be easily sterilized and used many times.
Researchers have shown how to coat glass and plastic with porous titanium dioxide. The fabrication process is straightforward, the materials are cheap, and the ceramic’s gas sensing performance is considerably improved compared with current devices.
Today’s medical device manufacturers are facing changing and more challenging requirements for their products. Users are demanding less-invasive devices, and in some cases, wearable devices that are robust and long lasting. Regulations are becoming ever more stringent and costly, especially in terms of biodegradability. Yet at the same time, device manufacturers want to meet user demands by including the latest technologies, while keeping their costs under control.
Washington State University researchers have developed a technology that is more than 30 times more sensitive than current lab-based tests in finding early stage cancer biomarkers in blood.
We are living in a digitally integrated and connected world. Evidenced by the use of smartphones, smartwatches, and other smart devices, there is no ending this trend. This holds true across many industries and applications, but is especially prevalent within medtech devices — a market that’s predicted to reach $432.6 billion by 2025.1
The advent of the COVID-19 pandemic has created uncertainty and delays in procedures, but hospitals and surgeons still need a steady supply of product, meaning that the orthopedics industry must keep innovating. One thing is certain, 2020 will be a turbulent year for procedure demand. Early on, analysts predicted that because many orthopedic procedures are elective, they would be postponed to help free up space for critically ill patients. While the recovery of orthopedic procedures has begun more quickly than analysts initially expected, it seems likely it will take longer than expected to reach full recovery as we look into 2021. June ordering patterns were already much higher than May, but the quicker recovery may indicate a second decline (W-shaped) versus a sharp decline followed by a quick recovery (V-shaped).
A device that monitors health conditions in the body using a person's sweat has been developed by Penn State and Xiangtan University researchers, according to Huanyu “Larry” Cheng, assistant professor of engineering science and mechanics, Penn State.
Conventional melanoma therapies, including chemotherapy and radiotherapy, suffer from the toxicity and side effects of repeated treatments due to the aggressive and recurrent nature of melanoma cells.
The security of connected health technology is often assumed to exist when it does not, or considered to be prohibitively expensive or complex, or, worst of all, relegated to an afterthought. This is dangerous thinking, especially as the industry increasingly moves to a smartphone-based command-and-control model for these safety-critical applications.
Over the years, technological innovation has allowed the medical equipment sector to become a mission-critical part of the healthcare industry, delivering such benefits as lower operating costs and improved patient outcomes. But competitive pressures are driving the need for device developers to provide a richer experience for users, incorporating broader capabilities and features and more options.
Scientists at EPFL have developed robust and easy-to-implement multicolor super-resolution imaging. The approach is based on the simultaneous acquisition of two spectral channels followed by spectral cross-cumulant analysis and unmixing. They exploit fluorophore blinking and spectral crosstalk for the generation of additional color channels with super-resolved images.
EPFL researchers have developed electronic fibers that, when embedded in textiles, can collect a wealth of information about our bodies by measuring subtle and complex fabric deformations. Their technology relies on transmission line theory and offers a host of applications, such as in healthcare and robotics.
A novel stretchable material, when used in light-emitting capacitor devices, enables highly visible illumination at low operating voltages, and it is also resilient to damage due to its self-healing properties.
Rice University neuroengineers have created a tiny surgical implant that can electrically stimulate the brain and nervous system without using a battery or wired power supply.
