The vast majority of diseases and disorders afflicting humans, ranging from arthritis to Zika fever, involve some level of inflammation. While inflammation is most familiar to us as pain, redness, and swelling, a slew of biochemical markers is associated with it as well.

One of these markers, the C-reactive protein, or CRP, which is secreted by the liver, is so commonly associated with inflammation that its presence in the bloodstream is a strong indicator of an underlying health condition.

Now, researchers at Caltech have developed a first-of-its-kind wearable skin sensor that can wirelessly detect the presence of CRP in human sweat. This sensor will make it easier for patients and medical professionals to monitor their health without the need for...
