Piezoresistive Accelerometer

Lub hauv paus ntawm piezoresistive accelerometer yog cov nyhuv piezoresistive. Nws siv lub micromachined cantilever beam lossis cov ntaub ntawv pov thawj ua los ntawm cov khoom siv semiconductor xws li silicon. Thaum lub accelerometer ntsib acceleration, lub inertial quab yuam ua rau cov pov thawj loj deform. Qhov no deformation stretches los yog compresses cov khoom piezoresistive txuas mus rau lub beam, ua rau muaj kev hloov nyob rau hauv nws cov hluav taws xob tsis kam. Los ntawm kev ntsuas qhov kev hloov pauv no hauv kev tiv thaiv (feem ntau yog siv Wheatstone choj Circuit Court), qhov loj ntawm qhov nrawm tuaj yeem suav tau raug.

Vim nws txoj kev khiav hauj lwm tshwj xeeb, piezoresistive accelerometers muab siab rhiab heev, kev ntsuas dav dav, cov qauv muaj zog, thiab siab - teb zaus. Txawm li cas los xij, lawv feem ntau muaj kev siv hluav taws xob ntau dua thiab muaj kev nkag siab rau qhov kub thiab txias (yuav tsum tau them nyiaj kub).

Raws li cov yam ntxwv no, lawv cov ntawv thov feem ntau yog tsom rau thaj chaw uas yuav tsum tau ntsuas qhov siab - zaus, siab- cuam tshuam (siab-g), dynamic xwm txheej.
