Imagine if taking a snapshot of your health were as easy as slapping a sticker on your skin. A new study finds that a tiny adhesive sensor can read what's going on in your body based on your sweat, and relay information about your well-being wirelessly to a smartphone. This type of wearable sensor could work as an alternative to blood tests to assess people's health one day, according to the researchers.
In the new study, scientists embedded chemical sensors and other devices into a soft, flexible silicone rubber disc, about the size and thickness of a quarter, that can easily stick to skin. The device is designed to collect and analyze sweat for key biomarkers, or markers of health. For instance, the sensor can show how people are responding to exercise, including whether someone needs to make adjustments, such as drinking more water or replenishing electrolytes.
