In their recent ECS Sensors Plus article, authors Leyllanne K. A. Souza, Maxwell D. Bridges, Thaisa A. Baldo, Wendell K. T. Coltro, and Charles S. Henry introduce an innovative and accessible approach to wearable biosensing by transforming a simple adhesive bandage into a high-performance electrochemical sensor.

Delivering low-cost, non-invasive, real-time health monitoring

As demand grows for non-invasive, real-time health monitoring, sweat has emerged as a valuable biofluid for tracking physiological biomarkers. In this study, researchers developed a flexible sensing platform using laser-induced graphene (LIG), a porous, conductive material created through laser processing, and transferred it onto a commercial adhesive bandage. The result is a lightweight, skin-conformal sensor capable of detecting key metabolites directly from sweat. (more…)

With its excellent temperature sensitivity and low thermal budget, this work offers promising applications in the field of advanced microsystems and wearable electronics. (more…)

ECS recognizes the importance of expanding opportunities for publishing in ECS journals as the science continues to evolve. The Society recently made changes to the sensors topical interest area (TIA). Submissions to the ECS Journal of Solid State Science and Technology (JSS) are now accepted along with the Journal of The Electrochemical Society (JES).

“With the rapid growth experienced by the sensor community, and the gradual blurring of boundaries between solid state and electrochemical sensing strategies, it makes eminent sense to have a single TIA for this topic for both journals,” said Krishnan Rajeshwar, JSS Editor-in-Chief, and Robert Savinell, JES Editor-in-Chief.

Most of us don’t stop to think about it, but the skin on our body is pretty remarkable. The largest organ in the body can detect pressure, temperature changes, pain, and touch, all made possible thanks to the many nerves and receptors underneath our skin. With all that said, it’s easy to understand why it’s hard to duplicate this unique organ. But, according to ScienceDaily, researchers are working to do just that. Their goal is to reproduce and transfer these qualities into a manmade electronic skin technology that can be used in prosthetic devices, wearable health monitors, robotics, and virtual reality.

A team of researchers from National Tsing Hua University and National Cheng Kung University, both in Taiwan, has developed a low-cost, portable medical sensor package that has the potential to alert users of medical issues ranging from severe heart conditions to cancer, according to a new study published in the ECS Journal of Solid State Science and Technology.

Portable medical devices have become an integral part of holistic health care, exhibiting huge potential in monitoring, medical therapeutics, diagnosis, and fitness and wellness. When paired with benchtop point-of-care instruments used in hospitals and urgent care centers, individuals are able to both increase preventative care measures and gain a more complete picture of their health.

According to the open access paper, “Field-Effect Transistor-Based Biosensors and a Portable Device for Personal Healthcare” (ECS J. Solid State Sci. Technol., 6, Q71 [2017]), researchers have reported the design, development, fabrication, and prototyping of a low-cost transistor-based device that can measure the C-reactive protein (CRP) in bloodstreams, which, when elevated, indicates inflammation that could be linked to heart attack, stroke, coronary artery disease, and a host of other medical diagnosis.

Engineers used tissue paper—similar to toilet tissue—to make a new kind of wearable sensor that can detect a pulse or a blink of an eye.

The sensor, which is light, flexible, and inexpensive, could be used for health care, entertainment, and robotics, researchers say.

Tearing tissue paper that’s loaded with nanocomposites and breaking the paper’s fibers makes the paper acts like a sensor. It can detect a heartbeat, finger force, finger movement, eyeball movement, and more, says Jae-Hyun Chung, an associate professor of mechanical engineering at the University of Washington and senior author of the paper in Advanced Materials Technologies.

“The major innovation is a disposable wearable sensor made with cheap tissue paper. When we break the specimen, it will work as a sensor.”
