Ib tsab xov xwm luam tawm hauv phau ntawv ceev xwm txheej ntawm cov khoom siv hluav taws xob (PET) Warp yarns thiab polyvinylidene fluoride (PVDF) Warft yarns. Cov kev ua tau zoo ntawm kev tsim kho siab sensor hauv kev sib raug zoo rau kev ntsuas siab raws li cov qauv weave tau ua qauv qhia ntawm ib daim ntaub ntawm kwv yees li 2 meters.
Cov txiaj ntsig qhia tau tias qhov rhiab ntawm lub siab sensor optimized siv 2/2 canard tsim yog 245% siab dua li ntawm 1/1 tus tsim qauv. Tsis tas li ntawd, ntau lub tswv yim tau siv los ntsuas qhov ua tau zoo ntawm cov ntaub, nrog rau kev ua kom zoo, ua kom pom, wrinkling, sib ntswg, thiab ntau tus neeg taw. Hauv txoj haujlwm no, cov ntaub so ntswg siab sensor nrog lub sensor pixel array kev nthuav tawm cov yam ntxwv sib txheeb ruaj khov thiab siab rhiab.

Cov kev loj hlob sai ntawm cov neeg ntse thiab cov khoom siv hluav taws xob tau muab rau cov khoom siv hluav taws xob tshiab raws li cov khoom siv hluav taws xob, thiab lawv cov ntawv thov, thiab cov tshuaj kho tau sai sai.
Piezoelectricity yog tus them hluav taws xob uas tsim rau ntawm cov khoom uas raug rau kev ntxhov siab ntxhov siab. Piezoelectricity hauv cov ntaub ntawv asymmetric tso cai rau txoj kev sib raug zoo rov qab ntawm kev ntxhov siab thiab hluav taws xob. Yog li ntawd, thaum ib qho ntawm cov khoom siv hluav taws xob ntawm lub cev yog lub cev hluav taws xob, tus nqi hluav taws xob yog tsim, thiab hloov ua lwm yam.
Cov cuab yeej siv cov khoom siv no tuaj yeem siv cov khoom siv dawb kho kom muab qhov kev xaiv hluav taws xob rau cov hluav taws xob uas siv lub zog me me. Cov hom khoom siv thiab cov qauv ntawm cov cuab yeej yog qhov tseem ceeb rau kev tsim cov khoom siv kov tau raws li cov khoom siv electromechanical. Ntxiv nrog rau cov khoom siv hluav taws xob siab inorganic, tshuab hloov tau cov tshuab hloov kho cov ntaub ntawv organic.
Polymers ua tiav rau hauv Nanofibers los ntawm cov hau hluav taws xob hauv hluav taws xob tau siv dav ua cov khoom siv hluav taws xob. Piezoelectric polymer nanofibers pab txhawb kev tsim cov ntaub ntawv pov tseg los ntawm kev muab hluav taws xob elasticity nyob rau hauv ntau yam chaw.
Rau lub hom phiaj no, piezoelectric polymers tau siv dav, suav nrog PVDF thiab nws cov derivatives, uas muaj zog piezoelectricity. Cov PVDF fibers yog kos thiab spun rau hauv cov ntaub rau cov ntawv thov piezoeltric nrog sensors thiab cov tshuab hluav taws xob.
