Two Health Sensors Unite in One Powerful Gadget

What’s not to love about a good flexible health sensor? Someday technology based on such bendable electronic tech might well replace some of those chunky wearables in the marketplace today with sleek, golden skin patches.

Now, a team at the UC San Diego Center for Wearable Sensors has created a stretchy skin patch that combines electrochemical sensors for alcohol, caffeine, glucose, and lactate with an ultrasound-based sensor that monitors blood pressure deep inside the body. Described in the journal Nature Biomedical Engineering, it’s the first wearable device that tracks heart signals and biochemical levels at the same time, the authors said.

“Conventionally, those two types of signals are monitored separately by different devices,” said study co-author Sheng Xu, a UCSD nanoengineer. “By bridging the gap between those two, we can get a more comprehensive view of what’s going on in the human body.”
