Stretching the boundaries of medical tech with wearable antennae

 E-Mail IMAGE: The wearable transmitter is designed to compress its top layer in a double arch pattern, shown here, to respond to movement without compromising signal transmission. view more  Credit: Huanyu Cheng, Penn State Current research on flexible electronics is paving the way for wireless sensors that can be worn on the body and collect a variety of medical data. But where do the data go? Without a similar flexible transmitting device, these sensors would require wired connections to transmit health data. Huanyu Larry Cheng, Dorothy Quiggle Career Development Assistant Professor of Engineering Science and Mechanics in the Penn State College of Engineering, and two international teams of researchers are developing devices to explore the possibilities of wearable, flexible antennae. They published two papers in April in Nano-Micro Letters and

Electrochemical Sensors for Targeting Salivary Biomarkers

Electrochemical Sensors for Targeting Salivary Biomarkers Image Credit: Fusionstudio / Shutterstock.com Why analyze saliva? One of the most common methods used to assist in a clinical diagnosis is blood analysis, which typically requires the collection of several microliters (µl) or milliliters (ml). The collection of blood samples requires the use of an invasive blood collection procedure that not only requires skilled personnel but can also be inconvenient and painful for the patient. Comparatively, a saliva sample is collected through a non-invasive and convenient technique, thus reducing the amount of stress put on the patient during its collection. These advantages also allow clinicians to easily obtain multiple samples at a more frequent and rapid rate while simultaneously reducing the potential risk of contaminating the sample during its collection.

Graphene-enhanced Window Films for the Automotive Industry

Graphene-enhanced Window Films for the Automotive Industry NEX, the nano-ceramic window-film contains graphene alongside tungsten and antimony tin oxide to provide drivers with crystal clarity as well as UV and glare reduction. Image Credit: stekautomotive.com The complementary properties of graphene and glass mean that they go together hand in hand excellently. The development of such fusions continues to be especially beneficial to the automotive industry. Graphene is a wonder material that is often promoted for its novel physical properties. This material, which consists of a single layer of carbon atoms in a two-dimensional hexagonal lattice arrangement, has mechanical strength, electric and thermal conductivity, and flexibility, thus making it an important component in the development of electronics. But this remarkable material has another, often less touted property, that, when coupled with these aspects, makes it useful for the development of glass and window films  �
