Wearable heart rate sensor accuracy didn’t vary across skin tones in small Duke study

Dive Brief: A study of heart rate sensors on six wearable device models found accuracy fell by 30% on average when subjects were walking compared to when seated at rest. Skin tone variations did not significantly affect heart rate measurement accuracy, according to a group of researchers at Duke University’s Department of Bioinformatics and Biostatistics​.… Read More »

Wearable Sweat Sensor to Measure Gout-Causing Compounds

Researchers from Caltech, Peking University in China, Santa Clara University, and University of California, Los Angeles have developed a new wearable sensor that can detect gout-causing compounds in sweat. The device relies on novel laser-engraved chemical sensors to detect gout-causing compounds uric acid and tyrosine at concentrations much lower than previously possible. Moreover, the same… Read More »
