Abstract

In a multi-sensor system and method of monitoring vital body signals during movement of a body of a human or an animal, acceleration sensors are placed at body locations in such a way that an acceleration angle change induced by the vital body signals differs between the at least two acceleration sensors. The retrieval of the vital body signals is achieved by extracting a wanted vital body signal based on measurement results from multiple sensors that may be motion contaminated. Three retrieval schemes are proposed, each with preferred sensor locations that provide optimal performance of retrieving the vital body signal(s).
