Researchers around Ali Javey from the University of California in Berkeley have developed a new sensor, which can be used in the future in arms and sweat bands to communicate information about the State of health of the who to the Smartphone in real time. Experts in the specialist journal nature published the results and the potential of new sensor technology.
The researchers in the development of new sensor mainly focused on the evaluation of the metabolic products of glucose and lactate and sodium and potassium ions. The new sensor measures not only the values, but also the main body temperature. This is important, because the collected values are what can at higher values also lead to distortions of the results depending on the body temperature. Thanks to the acquisition of body temperature, also integrated circuits can incorporate the data and thus largely neutralize distortions. In the form of a sweat band or bracelet are new, with the sensor fitted, wearables deliver fairly accurate values for lactate or glucose levels.
“Human sweat contains physiologically rich information, what makes this an attractive body fluid for non-invasive, portable sensors”, as main author Ali Javey. Several test subjects wore the devices, whose Sensoren are directly in contact with the skin and thereby drove sport.
