How microneedle sensors could watch your blood chemistry
Patches of tiny needles have already been shown to effectively deliver medications painlessly, and without a bloody mess. Now the tiny needles could also be used to monitor body chemistry in real time.
The new tech, developed by a team of biomedical engineers out of North Carolina State University, the University of California at San Diego, and Sandia National Laboratories, employs electrochemical sensors in the hollow channels of microneedles to detect certain molecules. The researchers reported their findings in the chemistry journal Talanta.
Current body chemistry monitoring involves taking samples, often before or after an event. Wearable micro-sensors, on the … Read more
