A wearable, freestanding electrochemical sensing system
(PHYSorg.com Chemistry)

In a new study published on Science Advances, Yichao Zhao and a research team in integrated bioelectronics and materials and engineering in the U.S. engineered a disposable, free-standing electrochemical sensing system (FESS). The FESS allowed them to realize a system-level design strategy to address the challenges of wearable biosensors in the presence of motion and allow seamless integration with consumer electronics. The team developed a FESS-enabled smartwatch, featuring sweat sampling, electrochemical sensing and data display or transmission, within a self-contained wearable platform. The team used the FESS-smartwatch to monitor the profiles of sweat metabolites among individuals in sedentary and high-intensive exercise settings.
