The rich store of information in…human sweat

[grow_thumb image=”https://telecareaware.com/wp-content/uploads/2016/02/sweat-sensor-wristband450.jpg” thumb_width=”200″ /]’Don’t sweat it’ may in future be the wrong thing to say. University of California-Berkeley researchers have developed a prototype sensor array on a band that successfully captures readings of multiple sweat analytes and sends the information to a smartphone app for analysis, making it the first device capable of continuous, non-invasive monitoring of multiple biochemicals in perspiration. The five sensors measure metabolites glucose and lactate, the electrolytes sodium and potassium, and skin temperature, which serves to calibrate the other readings in real time. The device (left), which can be in a wristband or headband form, also contains a flexible printed circuit board that amplifies the sensor signals and sends them to the smartphone app. The Berkeley researchers look forward to commercializing the technology to capture more analyte readings, for athletic performance, medical and fitness tracking usage–and in the longer-term, population-level studies for medical applications. We wonder how long it will be before these show up in a new model Misfit, Jawbone or Fitbit. Berkeley News   Hat tip to former TTA Ireland Editor Toni Bunting
