Great video! I'm currently working on a respiratory rate sensor and the idea of a full bridge of commercial strain gauges sensor is being attempted. Do you think it is possible to detect the variation of thoraxic volume of breathing with 2 or 4 strain gauges in bridge? Also considering whether the gauges are going to be fixed on a thin metal or plastic beam for using in a chest strap.
