Monitoring of biosignals plays important role in health and safe management in daily life. We have developed wide range load sensor based quartz crystal resonator (QCR load sensor) for casual sensing of biosignals such as pulse, respiration, and body motion. Expansion of the measurement range of the sensor is required for enhancing the usage of the QCR load sensor as casual sensing. We described the design of QCR load sensor to expand the measurement range of the QCR load sensor. Fabricated sensor with proposed design had practical resolution of 0.4 mN and maximum allowable load of 600 N, so that we successfully enhanced the measurement range of the QCR load sensor to 1.5 x 106.
