Sensor yokhazikika,sensor yothamangapogwiritsa ntchito mfundo ya inertia, yomwe ingapereke chidziwitso chodandaula chokhudzana ndi mphamvu yokoka.Sensor iyi imagwiritsidwa ntchito kwambiri pakuwunika momwe zida ziliri.

Sensor yoyambira kwambiri si sensor kwenikweni, imangokhala chosinthira chopangidwa ndi mpira pansi.Pamene ngodya ya chipangizocho imapendekeka, mpirawo umadutsa pansi pambuyo pa malire ena, ndipo kugwirizana kwa magetsi ndi bolodi kumapanga chizindikiro.Kuchokera ku mfundo zake, titha kuyitcha kuti chosinthira chamagetsi chamagetsi.

Pambuyo pake, sensa yoyambira yoyambira imakhala ndi kukana kapena madzi a capacitor pakhoma losindikiza.Pamene chipangizocho chimakonda, madzi otaya amasintha, potero amasintha kukana kapena capacitor wa dera lamkati, ndiyeno kuyang'anitsitsa mwachindunji kupyolera muzitsulo zozungulira.Panthawiyi, sensa yotsatsira imatha kupereka kale deta yolondola komanso yodalirika, koma chosowa ndi chakuti sensa yokhayo imakhala pachiwopsezo cha kusokonezedwa kwakunja, ndipo liwiro la kuyankha silili lachangu.

Ngakhale sensa yotengera kutengera MEMS ikufaniziridwa ndi luso laukadaulo lamadzimadzi, yathetsa zofooka za liwiro la kuyankha ndi moyo wautumiki, koma vuto la kuzindikira kwa MEMS silinachepe.Ntchito ndi kulondola kwa sensa yotsatsira imakhudzidwa ndi zinthu zosiyanasiyana, monga "double axis" mu chithunzi pamwambapa.Kusankhidwa kwa axis kuyenera kusankhidwa malinga ndi ntchito yeniyeni.Kusankhidwa kosayenera kwa shaft kudzakhudza kwambiri zotsatira za kuyeza.Zinthu zina ndi monga kutentha, kupendekera kwa sensor scale, linearity, ndi cross-axis sensitivity.

Sensor yotsatsira pambuyo pa kuphatikizika kwa sensa imakhudzidwa kwambiri ndi kuyankha kofulumira pansi pamikhalidwe yamphamvu, koma sidzakhudzidwa ndi "owonjezera" mathamangitsidwe.Kuphatikizidwa ndi kukhazikitsidwa kwa ma aligorivimu osiyanasiyana anzeru, sensor ya MEMS yazindikira ntchito zanzeru monga kusinthika kwa bandwidth ndi kudzizindikira.Pansi pa izi, ngakhale m'malo omwe kugwedezeka ndi mphamvu zimakhala zamphamvu, kachipangizo kameneka kamatha kupeza chidziwitso chokwanira komanso chodalirika.
