In this paper a method for estimation of heart rate, respiratory rate and motion by using optic-fibre wrapper around person's chest is performed along with simultaneous acquisition from attached referential body sensors, i.e. ECG, nasal thermal respiration sensor and two accelerometers. Optical fibre with an interferometer is a sensitive device that detects physical changes of the length of optical fibre. When wrapped around the chest or embedded in the clothes, heartbeats, respiration and motion causes its perturbation, that allow entirely unobtrusive monitoring of person's heart rate by processing captured interferometric signal. An experiment with 4 subjects was performed. Signals were acquired during sequential walking and resting periods for each subject. The obtained results confirm good estimation of motion events and satisfying estimation of heart and respiratory rate, which is are more successful during resting periods.
