Abstract
The development of an integrative quartz-resonance pressure sensor is explained.Quartz-crystal material is applied to process the elastic film
and the tuning fork quartz-crystal force-sensing resonator is used to detect the pressure.The volume of the sensor is reduced
and the manufacture complexity is decreased.The measuring range of the sensor is 0
