Tracking physiological health with wearable devices

Background: Technological advances allow for accurate tracking of physiological parameters. Heart rate, blood pressure and activity level have long been used, but it is now possible to analyze biochemical parameters like lactate and glucose in real time using simple wearable devices. Furthermore, it has been recently shown that biochemical biomarkers in sweat can be used to monitor physiological health.

Aim: Provide a literature overview of novel tools for analyzing biochemical physiological parameters using wearable devices and describe their use in monitoring health and disease.
