Tare da saurin haɓakar hankali na wucin gadi, Ana amfani da firikwensin matsa lamba mai girma a cikin kayan aikin wucin gadi, mutummutumi masu hankali, fatar jiki da kayan lantarki masu sawa. Na'urori masu auna matsa lamba dangane da ƙarfe na gargajiya da kayan semiconductor na inorganic suna da babban hankali, amsa mai sauri da kwanciyar hankali mai kyau, amma kewayon ji yana da iyaka, sassauci ba shi da kyau, kuma shiri yana da rikitarwa, kuma farashin yana da yawa.
Na'urar firikwensin matsin lamba na piezoresistive dangane da abubuwan haɗin gwiwar polymer (CPC) yana da abũbuwan amfãni daga cikin sauki tsari, mai kyau sassauci da sauƙin tarin sigina. Lokacin da aka sanya matsi na waje, Ana sake tsara hanyar sadarwar gudanarwar da ke cikin hadadden polymer ɗin nan da nan, yana haifar da canji a juriya. Haɗaɗɗen kayan aikin polymer tare da tsarin tsari mai girma uku ana ɗaukar su manufa don na'urori masu auna siginar piezoresistive saboda ƙarancin ƙarancinsu., high porosity da kyau elasticity.
Polyimide nanofiber mai aiki (PINF)/MXene hada airgel tare da hankula "Layer-strut" Tawaga daga Jami'ar Zhengzhou ne suka ƙera tsarin nanofiber multistage tare da haɗin gwiwar Cibiyar Nanoenergy da Tsare-tsare ta Beijing., Kwalejin Kimiyya ta kasar Sin, ta hanyar bushewa-bushewa da tsarin ƙaddamarwa na thermal. Godiya ga tsari mai ƙarfi da haɗin gwiwa mai ƙarfi tsakanin PINF da MXene, hadewar airgel yana da yawa kamar ƙasa 9.98 mg□cm-3, zai iya jure matsanancin yanayin zafi daga -50 ℃ zuwa 250 ℃, iri har zuwa 90%, da juriya ga gajiya fiye da haka 1000 hawan keke. Lokacin amfani dashi azaman firikwensin piezoresisor, karfin ji ya kai 85.21 kPa (corresponding to 90% strain), yana nuna ƙayyadaddun ganowa mara ƙarancin kParfdaidai daorrespiri to 0.5% strain), a kan 1000 hawan keke na juriya gajiya da kyakkyawan kwanciyar hankali da haɓakawa a cikin matsanancin yanayi. Bugu da kari, da hydrophobicity da multistage pore tsarin na composite aerogels kuma suna da kyau mai-ruwa rabuwa yi., adsorption iya aiki na 55.85 ~ 135.29 g-g-1, za a iya sake yin fa'ida. Ana sa ran binciken zai samar da sabon dandamali na multifunctional don motsin ɗan adam / gano siginar jiki da ingantaccen mai / ruwa rabuwa., Kuma ta "Mai nauyi, Superelastic, da Hydrophobic Polyimide Nanofiber/MXene Composite Airgel don Wearable Piezoresistive Sensor da Rarraba Mai/Ruwa  "Aikace-aikace" ana buga shi a cikin sabuwar fitowar Na'urori masu Aiki na Ci gaba.
