title: A multi sensing method for robust measurement of physiological parameters in wearable devices.
abstract: The monitoring of physiological parameters such as heart rate, ventilatory rate, or oxygen saturation is a commonly used practice in the medical field. Many clinical solutions exist, based on the use of specific sensors, dedicated for bedside patient's vital functions monitoring at hospital. But the implementation of such sensors in ambulatory situations is rendered extremely difficult because of many artifacts induced by the movements of the subject that make the measures unusable. We have designed an original method for robust measurement of physiological parameters dedicated for wearable devices. The method is based on a multi sensing technique using, at least, two sensors of different nature or placed at different sites, for each parameter. In order to illustrate this method, we have developed a headset device including two heart rate (HR) sensors and two ventilatory rate (VR) sensors. This device has been evaluated on 6 healthy volunteers during exercises. This test showed the physiological values of HR and VR from the headset device stability and efficiency.
