几年已广泛使用的单晶硅压力传感器。尽管半导体技术制造的，他们也对电阻的原则运作。在单晶硅半导体（压电效应）的电阻变化是大大高于标准应变计，其电阻变化与几何结构的变化。在掺杂半导体的导电性变化（晶体网格压缩或拉伸），可以由一个非常小的机械变形产生影响。使用温度补偿和放大信号信号调理集成电路，分立电路，提供优越的性能。Maxim>AppNotes>AUTOMOTIVESENSORSIGNALCONDITIONERSKeywords:piezoresistive,pressuresensors,micromachinepressuresensors,pressurecontrolsystems,Dec07,2001monocrystalline,silicontransducer,temperature,pizoresistiveAPPLICATIONNOTE871DemystifyingPiezoresistivePressureSensorsAbstract:Monocrystallinesiliconpressuresensorshavecomeintowideuseinrecentyears.Thoughmanufacturedwithsemiconductortechnology,theyalsooperateontheresistiveprinciple.Theresistancechangeinamonocrystallinesemiconductor(apiezoelectriceffect)issubstantiallyhigherthanthatinstandardstraingauges,whoseresistancechangeswithgeometricalchangesinthestructure.Conductivityinadopedsemiconductorisinfluencedbyachange(compressionorstretch……
