The project aims to measure energy expenditure and physiological status changes in the industrial work environment (including human robot collaboration) and in a controlled study within the 24-h circadian context. We will compare three affordable wearable activity devices with capability to track heart-rate, body temperature, and galvanic-skin response and test their applicability against indirect calorimetry. Dr. SangHyun Lee and Dr. Vineet Kamat will test wearable activity and health-monitoring devices within industrial environment and their applicability to understand the physiological status of workers in human-robot collaboration setting. Dr. Katarina Borer will test these devices within a 24-h circadian context and also measure postprandial glycemia with a continuous glucose-monitoring device. The projects will involve developing and testing protocol, algorithms, and software to maximize the potential of these emerging devices.
