Force measurement plays an important role in the bio-medical field due to measuring bio-signal information (body weight, pulse wave and respiration) by non-binding measurement method. Conventionally, weight scale measures only body weight because it does not have enough measurement range. We have realized a load sensor using quartz crystal resonator (QCR) with a measurement range of the order of 106. In this paper, Wide range weight scale using. QCR load sensors were proposed in order to expand the application of the QCR load sensor. We also conducted the calibration of the force characteristic of the fabricated QCR force sensor and measurement of body weight, ballistocardiogram and water intake.
