Automatic breathing detection is an important medical issue in apnea syndrome in newborn and/or quite old people, or to detect the response of body to physical activity. We detect the breathing using a conductive rubber to sense chest displacement. At the best of our knowledge, this is the first sensor based on the conductive rubber specifically designed to measure the breathing frequency. The conductive rubbers offer quite cheap and sensitive devices for dilatation measurement. Signal detection is easier than in piezo sensor, compared to inductive displacement it is more simple. We expect it could be more rugged than inductive sensors and then other kind of resistive sensors. We are also studying ageing of this device for electrical and mechanical stress, and we plan to test more kind of conductive rubber. The application of the belt is not so tight to be oppressive so that it could be worn for long time, allowing us to plan for continuous measurement and recording.
