Iterambere ryihuse ryimashini zifite ubwenge nibikoresho byifashishwa bya elegitoroniki byambara byatumye havuka ibikoresho byinshi bishya bishingiye ku byuma byoroha byoroha, kandi ibyo bakoresha mu bikoresho bya elegitoroniki, inganda, n’ubuvuzi biratera imbere byihuse.
Piezoelectricity ni umuriro w'amashanyarazi ukorwa kubintu biterwa no guhangayika.Piezoelectricity mubikoresho bitamenyerewe ituma umubano uhinduka hagati yumubyigano wumuriro n amashanyarazi.Kubwibyo, iyo igice cyibikoresho bya piezoelectric byahinduwe kumubiri, hashyirwaho umuriro w'amashanyarazi, naho ubundi.
Ibikoresho bya Piezoelectric birashobora gukoresha isoko yubukanishi yubuntu kugirango itange ubundi buryo bwamashanyarazi kubikoresho bya elegitoronike bitwara imbaraga nke.Ubwoko bwibikoresho nuburyo bwibikoresho nibintu byingenzi byingenzi kugirango habeho ibikoresho byo gukoraho bishingiye ku guhuza amashanyarazi.Usibye ibikoresho byinshi bidafite ingufu za organic organique, ibikoresho bya organic organique byoroshye byanashakishijwe mubikoresho byambara.
Polymers yatunganijwe muri nanofibers hakoreshejwe uburyo bwa electrospinning ikoreshwa cyane nkibikoresho byo kubika ingufu za piezoelectric.Piezoelectric polymer nanofibers yorohereza kurema ibishushanyo mbonera bishingiye kumyenda yububiko bushobora kwifashishwa mugutanga amashanyarazi ya elegitoronike ashingiye kumashanyarazi muburyo butandukanye.
Kubwiyi ntego, polymers ya piezoelectric ikoreshwa cyane, harimo PVDF nibiyikomokaho, bifite piezoelectricity ikomeye.Izi fibre ya PVDF irashushanywa kandi ikazunguruka mu myenda ya porogaramu ya piezoelectric harimo sensor na generator.

Muri iki gihe, imashini itanga imyenda ishingiye kuri filime ya PVDF ya nanofiber yubatswe hifashishijwe uburyo bwa elegitoronike ya jet-50 ikurikirana, aho gukoresha nozzles 50 byorohereza umusaruro wa mato ya nanofiber ukoresheje umukandara uzunguruka.Imiterere itandukanye yububiko ikozwe hifashishijwe PET yintambara, harimo 1/1 (ikibaya), 2/2 na 3/3 imbavu.
Ibikorwa byabanje byatangaje ko hakoreshwa umuringa mu guhuza fibre mu buryo bwo guhuza insinga z'umuringa ku ngoma zo gukusanya fibre.Nyamara, imirimo iriho igizwe ninkoni zumuringa zibangikanye zingana na cm 1.5 zitandukanijwe kumukandara wa convoyeur kugirango zifashe guhuza uruziga rushingiye ku mikoranire ya electrostatike hagati ya fibre zishyurwa zinjira hamwe nubushyuhe hejuru ya fibre ifatanye na fibre y'umuringa.
Bitandukanye na sensor ya capacitif cyangwa piezoresistive sensor, sensor sensor ya tissue yatanzwe muriyi mpapuro isubiza imbaraga nyinshi zinjiza kuva 0.02 kugeza 694 Newtons.Byongeye kandi, icyifuzo cyerekana igitutu cyerekana imyenda yagumanye 81.3% yumwimerere winjiye nyuma yo gukaraba bisanzwe, byerekana igihe kirekire cyumuvuduko.
Byongeye kandi, indangagaciro zo kwiyumvisha gusuzuma voltage n'ibisubizo bigezweho kuri 1/1, 2/2, na 3/3 kuboha imbavu byerekanaga imbaraga za voltage nyinshi ya 83 na 36 mV / N kugeza 2/2 na 3/3 byumuvuduko wimbavu.Ibyuma 3 byerekana ibyuma byerekana 245% na 50% byunvikana kuri ibyo byuma byerekana ingufu, ugereranije na 24 mV / N ibyuma byerekana ibyuma 1/1.
