Wide-range load sensing of newborn's biosignals with quartz crystal resonator

We present a device for non-invasive detection of newborn's multi-biosignals. It is difficult to detect newborn's biosignals such as weight, heart rate and respiratory rate non-invasively due to the necessity of measuring various range signals. To detect these biosignals, we developed a load sensing device which has wide measurement range using quartz crystal resonator (QCR). As results, we succeeded in detecting newborn's respiration non-invasively.
