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.
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.
The device simultaneously measures uric acid (UA) and ascorbic acid (AA) using differential pulse voltammetry, demonstrating strong sensitivity, reproducibility, and selectivity within physiologically relevant ranges. Notably, the sensor maintains reliable performance in artificial sweat while remaining low cost and simple to fabricate—an important consideration for scalable wearable technologies.
By integrating advanced carbon materials with everyday medical supplies, this work highlights a practical pathway toward affordable, disposable wearable sensors for health monitoring, athletic performance tracking, and point-of-care diagnostics.
This research underscores the growing impact of electrochemical innovation in wearable systems and reinforces the mission of ECS Sensors Plus to showcase forward-looking developments in sensor science and technology.
New from the President in the winter 2025 issue of ECS InterfaceIn “From the President: Advocating for Science = Positively Affecting the World,” ECS President James (Jim) Fenton reflects on the critical role science advocacy plays in shaping a brighter, more equitable future for all.
In a time when science and technology are at the forefront of global progress, this thoughtful piece highlights how each of us—whether you’re a researcher, educator, student, or industry partner—can contribute to positive change by championing science in our communities and beyond. (more…)
An exciting, cutting-edge contribution to the scholarly record—“Electrochemically Induced Deposition (ECiD) of Lithium Phosphate and the Effect of Reaction Parameters” by Ali Amir Saleh, Louis L. De Taeye, Sai Gourang Patnaik, Genis Vanheusden, and Philippe Vereecken—features in the March issue of ECS Advances.
This open-access article dives into a versatile electrochemical approach for synthesizing thin films of lithium phosphate on conductive surfaces via electrochemically induced deposition (ECiD)—a method with broad relevance for materials that are traditionally challenging to deposit electrochemically. By combining experimental investigation with numerical modelling, the authors illuminate how reaction conditions like current density, pH, and electrolyte composition shape the deposition mechanism and resulting material morphology. Their insights advance understanding of how to tailor ECiD processes for desired outcomes, knowledge that will benefit researchers across electrochemistry, energy materials, and solid state science.

Recent advances in III-nitride heterostructures continue to push the boundaries of high-frequency and high-power device performance. A new study, “Demonstrating the Effects of Growth Temperatures of Al(In)GaN Back Barrier on Transport Properties of InAlGaN/GaN Heterostructures,” takes a close look at how carefully tuning growth conditions can directly shape electronic behavior at the nanoscale.
In this article, the authors—Hoang-Tan-Ngoc Nguyen, Rahul Rai, Quoc-Huy Nguyen, Quoc Viet Hoang, Ngoc Quang Huy Dinh, Chan-Yuen Chang, Chien-Wei Chen, You-Chen Weng, Hao-Chung Kuo, Ching-Ting Lee, and Edward-Yi Chang—investigate how the growth temperature of an Al(In)GaN back barrier fabricated using metal-organic chemical vapor deposition (MOCVD) influences the structure and performance of InAlGaN/GaN heterostructures. By minimizing the temperature gap between the channel and back barrier layers, the researchers achieved highly coherent growth with smooth surfaces, sharp interfaces, and no detectable threading dislocations. These structural improvements translated into measurable performance gains: higher electron mobility, reduced sheet carrier density, and stronger electron confinement. (more…)

Dr. Loraine Torres-Castro
Physicist Dr. Loraine Torres-Castro, Battery Safety Lead at Sandia National Laboratories, is serving as the lead organizer for the A01—New Approaches and Advances in Electrochemical Energy Systems Symposium at the 249th ECS Meeting in Seattle, WA, this spring.
In a recent interview with ECS staff, Dr. Torres-Castro shared insights into the rewards and complexities of symposium leadership, encouraging colleagues to pursue similar roles. She is part of a dynamic new organizing team—which includes Dr. Yuliya Preger (Sandia National Laboratories) and Prof. Golareh (Goli) Jalilvand (University of South Carolina)—that has introduced a collaborative leadership model. Under this arrangement, the leads rotate each meeting: Dr. Preger led the 248th Meeting symposium, while Prof. Jalilvand is slated to lead it at the 250th.

Heavy-Duty Vehicles (HDV) powered by hydrogen-based Proton Exchange Membrane (PEM) fuel cells offer a cleaner alternative to the diesel-powered internal combustions engine vehicles for decarbonization of long-haul transportation sectors. The development path of sub-components for HDV fuel cell applications is guided by the Total Cost of Ownership (TCO) analysis of the truck. TCO analysis suggests that the cost of the hydrogen fuel consumed over the lifetime of the HDV is more dominant due to the operation of the trucks for longer mileage (~a million miles) than the fuel cell stack Capital Expense (CapEx). Commercial HDV applications consume more H2 fuel and demand higher durability and hence the TCO of the vehicle is largely related to the fuel cell efficiency and durability of catalysts. This article is written to bridge the gap between the industrial requirements and academic activity for advanced cathode catalysts with an emphasis on durability. From a materials perspective, the underlying nature of the carbon support, Pt-alloy crystal structure, stability of the alloying element, cathode ionomer volume fraction, and catalyst-ionomer interface play a critical role in improving performance and durability. We provide our perspective on four major approaches, namely, mesoporous carbon supports, ordered PtCo intermetallic alloys, thrifting ionomer volume fraction, and shell-protection strategies that are currently being pursued. While each approach has its merits and demerits, their key developmental needs for the future are highlighted.

ECS Sensors Plus seeks contributions for a focus issue on electrochemical biofilm sensing.
Biofilms, which are widespread in natural systems and engineered applications, play important roles in industrial water treatment, the food industry, medical applications, and environmental sustainability. In these contexts, biofilm development often causes operational efficiency problems, product or equipment contamination, and adverse effects on human and environmental health. Conventional methods for biofilm detection are often time-consuming and non-real time. Electrochemical methods possess unique properties in sensitivity and speed and can work with miniaturized devices. New advances in materials science and microfabrication technology, and the development of advanced data analytics over the last few years, have further broadened the capabilities of electrochemical sensors for real-time monitoring of biofilms.
