Body Biolytics adds Hydration Biomarker for Wearable Optical Sensor

Posted on Sep 30, 2015 in Biometrics, Hydration, Wearable Tech | No Comments

Body Biolytics announces newly developed digital hydration biomarkers that are extracted from optical sensors embedded in a growing number wearable devices on the market, including wristbands and sensorized clothing. The biomarkers promise to provide continuous, non-invasive hydration status monitoring for various consumer and medical use cases.

Optical sensors are based on photoplethysmography (PPG), a clinically-approved technique that detects
blood volume changes in the microvascular bed of tissue. This mature technology is prevalent in hospitals to monitor patient blood oxygen saturation levels; for example, the familiar pulse oximeter. A growing number of wearables use PPG sensors for continuous heart rate monitoring. Body Biolytics digital biomarker algorithms exploit these same sensors to provide valuable information about hydration levels, as well as respiration rate.
