Kugwiritsa ntchito semiconductor kukakamiza kugwiritsa ntchito siyicnon yoyala ngati gawo lapansi. Choyamba, siyickon yoyala imapangidwa kukhala mbali yovuta kwambiri ndi geometry inayake. Pa gawo lokhala ndi nkhawa kwambiri la silikicon limakhala lofatsa, mawonekedwe anayi a P-forfsion Opsinjika amapangidwa motsatira njira zosiyanasiyana za tirigu. Mothandizidwa ndi mphamvu yakunja, kusintha kwa zifukwa zokana kukana kumasiyanitsa magetsi. Chitsiriro ichi cha tirigu komanso kupsinjika ndi mtima wa sporser, yomwe nthawi zambiri imatchedwa Pridger Bridge (monga tikuonera Chithunzi 1). Makhalidwe a mlatho wa Piezoressist ali motere: ① Makhalidwe otsutsa a manja anayi a mlatho ndi ofanana (onse r0); ② Piezoressist zotsatira za manja oyandikana ndi mlathowo ndi ofanana mu mtengo ndi osiyana ndi chizindikiro; ③ Kutentha kutentha kogwirizana ndi manja anayi a mlatho ndi ofanana, ndipo nthawi zonse amakhala nthawi yofanana. Mu mkuyu. 1, R0 ndi mtengo wokana popanda kupsinjika kutentha kwa firiji; RT ndiye kusintha komwe kumayambitsidwa ndi kutentha kwa kutentha kwa kukana (α) pomwe kutentha kumasintha; Υ rΔ ndikusintha kukana kutsutsana chifukwa cha zovuta (jug); Mphamvu zotulutsa za mlathowu ndi u = i0 rδ = i0rg gredgerget).

Komwe i0 imakhala yokhazikika yapano ndipo e imasungunuka yamagetsi yamagetsi. Mphamvu yamagetsi yotulutsa Piezoresist yolingana mwachindunji ndi mavuto (ε) ndipo alibe chochita ndi RT chifukwa chongoyambitsidwa ndi kutentha kwa kutentha kwa kutentha kwa sensor. Sensor yogwiritsidwa ntchito kwambiri yogwiritsiridwa ntchito ndi sensor yofufuza zovuta zamadzimadzi. Katundu wake waukulu ndi kapisozi wopangidwa ndi monocrystalline diicon (monga tikuonera Chithunzi 2). Diaphragm imapangidwa mu kapu, ndipo pansi pa chikho ndi gawo lomwe limakhala ndi gawo lakunja, ndipo mlathowo umapangidwa pansi pa kapu. Mitembo yoikapo imapangidwa ndi zinthu zomwezi zamitundu zomwezi, kenako ndi diaphragm imalumikizidwa ndi maziko. Sensor mtundu uwu uli ndi maubwino omvera kwambiri, voliyumu yaying'ono komanso yokhazikika, ndipo yagwiritsidwa ntchito kwambiri muvigation, malo oyendetsa ndege ndi zida zachipatala.
