to detect blood-oxygen levels. Beyond the measurement of blood oxygen, Arias has developed a multi-sensor platform capable of photoplethysmography and biomarker detection from human sweat. These sensing platforms allow insight into the physiological state of the human body. The sweat sensors developed by Arias consist of lactate, sodium and ammonium sensors. Arias has also investigated materials and devices that can harvest and store energy.
