Nkhani yofalitsidwa mu magazini ya NTJ Magetsi osinthika pa zojambulajambula za piezoelections amagwiritsa ntchito ma polp ulusi ndi polyvinylidene fluoride (PVDF). Kugwirira ntchito kwa sensor yotukuka komwe kumakhudzana ndi kuchuluka kwa kukakamizidwa kutengera mawonekedwe ozungulira kumawonetsedwa pa nsalu pafupifupi mamita pafupifupi 2.
Zotsatira zake zikuwonetsa kuti kumverera kwa sensor kukhazikika pogwiritsa ntchito kapangidwe ka 2/35% kuposa momwe 1/1 Card. Kuphatikiza apo, zosindikizira zosiyanasiyana zimagwiritsidwa ntchito kuwunika magwiridwe antchito okwanira, kuphatikizapo kusinthasintha, kufinya, kufinya, kupindika, komanso kusunthika, komanso kusunthika, komanso kusunthika kosiyanasiyana kwa anthu. Mu ntchitoyi, kuponderezedwa kwa minofu yokhala ndi pixel pixel pixres kumawonetsa mawonekedwe okhazikika ndi chidwi chachikulu.
Mpunga. 1. Kukonzekera kwa PVDF ulusi ndi nsalu zambiri. Chithunzi cha njira zamagetsi 50 zomwe zimagwiritsidwa ntchito kupanga maphwando a PVDF Nanofiber, pomwe ndodo zamkuwa zimayikidwa zofanana Chithunzi cha B Sem ndi diametergariti yogawidwa kwa ulusi wa PVDF. C Sem chithunzi cha ulusi wakhungu. d ku Tansile Mphamvu ndi Kupsinjika Pakuthwa kwa Yarn ya Kly-Ply Play ngati ntchito yokhotakhota. E X-ray mawonekedwe a ulusi anayi akuwonetsa kukhalapo kwa magawo a alpha ndi beta. Kim, DB, Han, J. SHA, SM, Kim, Bang, Park, H. R ET Al. 2022)
Kukula kwapamwamba kwa maloboti anzeru a magetsi ndi zida zamagetsi zomwe zidapangitsa kuti ziweto zambiri zatsopano zokhala ndi maluso osinthika, komanso ntchito zawo zamagetsi, makampani, ndi mankhwala akukula msanga.
Piezoelertricity ndi magetsi opangidwa pamagetsi omwe amapangidwa pazinthu zomwe zimachititsidwa ndi zovuta zamakina. Piezooelertctity wazinthu za asymmetric imalola ubale wosinthika pakati pa kupsinjika kwamakina ndi magetsi. Chifukwa chake, pamene chidutswa cha piezoelectric chimakhala chosakanizidwa chathupi, magetsi amapangidwa, ndipo mosemphanitsa.
Zipangizo za Pizzoelertc amatha kugwiritsa ntchito gwero laulere lamakina kuti mupereke gwero lina lazinthu zamagetsi zamagetsi zomwe zimagwiritsa ntchito mphamvu zochepa. Mtundu wa zinthu ndi kapangidwe ka chipangizocho ndi magawo ofunikira pakupanga zida zokhudzana ndi ma electomera colling. Kuphatikiza pa zida zamagetsi zam'madzi, zida zosinthika zomwe zimasinthidwanso mu zida zolemetsa.
Ma polima adakonzedwa mu nanofiber ndi njira zamagetsi amagwiritsidwa ntchito ngati zida zosungira za piezzoelelectric. Piezoelectric polymer imatsogolera kapangidwe kazinthu zopangidwa ndi nsalu zogwiritsira ntchito zochulukirapo popereka magetsi m'badwo wamakina m'malo osiyanasiyana.
Pachifukwa ichi, ma poizoni a piezoelect amagwiritsidwa ntchito kwambiri, kuphatikizapo pvdf ndi zochokera, zomwe zimakhala ndi piezooelect yolimba. Zithunzizi za PVDF zimakokedwa ndi kupindika mu nsalu za pizzoelectric kuphatikiza masensa ndi majedzore.
Chithunzi 2. Madera akuluakulu amakhala ndi zinthu zakuthupi. Chithunzi cha nthiti yayikulu ya 2/2 yaintaneti mpaka 195 cm x 50 cm. Chithunzi cha B Sem weft dongosolo lokhala ndi PVDF kutchentchedwa ndi zitsulo ziwiri. C bdulus ndi mavuto opumira mu nsalu zingapo ndi 1/1, 2/2 ndi 3/3 weft efge. d ndi ngodya yopachikika yoyesedwa pa nsalu. Kim, DB, Han, J. SHA, SM, Kim, Bang, Park, H. R ET Al. 2022)
Pantchito yamakono, nsalu zophatikizika zochokera pa PVDF nanofizar njira yopanga ma elekitiyi 50-ndege, pomwe ma nozzles amathandizira kupanga lamba wozungulira wa nanofib. Magulu osiyanasiyana a uve odetsedwa amapangidwa pogwiritsa ntchito ulusi, kuphatikiza 1/1 (mwachilungamo), 2/2 ndi 3/3 nthiti.
Ntchito yapitayi yanena kuti kugwiritsa ntchito mkuwa kugwirizanitsidwa kwa mawonekedwe a fibe mu mawonekedwe ogwirizana pamiyala yosungirako ng'oma. Komabe, ntchito yapano ili ndi ndodo zofananira zamkuwa 1.5 masentimita pa lamba lonyamula kuti lithandizire kusinthitsa ma spinriction assotic magalimoto omwe ali ndi zingwe zolumikizidwa ndi ulusi wamkuwa.
Mosiyana ndi zojambulajambula zomwe zidanenedwa kale kapena zopindika za minyewa zomwe zimafunsidwa patsamba lino limayankha magawo osiyanasiyana kuchokera ku 0.02 mpaka 694 zatsopano. Kuphatikiza apo, mawonekedwe ophatikizika a nsalu ophatikizidwa ndi 81.3% ya zothandizira zake zoyambirira pambuyo pa belu lalitali, zomwe zikuwonetsa kulimba kwa sensor.
Kuphatikiza apo, chidwi ndi mphamvu zowunikira magetsi komanso zotsatira zaposachedwa kwa 1/1, 2/2, ndi 3/3 nthiti zomverera bwino kwambiri za 83 ndi 36 mv ndi 3/3 nthiti. 3 Wett neshurs adawonetsa 245% ndi 50% ya 50% ya ma tony, motsatana, poyerekeza ndi sensa ya 24 / n yasungunuka 1/1.
