Maqaal lagu daabacay joornaalka npj Flexible Electronics ayaa ka warbixinaya soo saarista cadaadiska piezoelectric ee loogu talagalay dharka iyadoo la adeegsanayo polyetylen terephthalate (PET) dunta warp iyo polyvinylidene fluoride (PVDF) dunnooyinka weft.Waxqabadka dareemaha cadaadiska horumaray ee la xidhiidha cabbiraadda cadaadiska ee ku salaysan qaabka tolmada ayaa lagu muujiyay miisaan dhar ah oo qiyaastii 2 mitir ah.
Natiijooyinku waxay muujinayaan in dareenka dareemaha cadaadiska la hagaajiyay iyadoo la adeegsanayo naqshadeynta 2/2 kanard ay 245% ka sarreyso kan 1/1 naqshadeynta canard.Intaa waxaa dheer, qalabyo kala duwan ayaa loo isticmaalay si loo qiimeeyo waxqabadka dharka la hagaajiyay, oo ay ku jiraan dabacsanaan, tuujin, laalaab, qalloocin, iyo dhaqdhaqaaqyo kala duwan oo bini'aadam ah.Shaqadan, dareemaha cadaadiska nudaha ku salaysan ee leh array pixel-ka ayaa muujiya sifooyin la fahmi karo oo deggan iyo dareen sare.

Horumarka degdega ah ee robot-yada caqliga leh iyo aaladaha elegtarooniga ah ee la xidhan karo ayaa keenay qalabyo badan oo cusub oo ku salaysan dareemayaasha cadaadiska dabacsan, codsiyadooda elektiroonigga ah, warshadaha, iyo dawooyinka ayaa si degdeg ah u koraya.
Piezoelectricity waa koronto ka dhalata shay ay ku jirto cadaadis farsamoPiezoelectricity ee agabka asymmetrical waxay u ogolaataa xiriir toosan oo rogi kara inta udhaxeysa culeyska farsamada iyo qarashka korantada.Sidaa darteed, marka qayb ka mid ah walxaha piezoelectric ay jir ahaan u qaabaysan yihiin, koronto ayaa la abuurayaa, iyo liddi ku ah.
Qalabka Piezoelectric waxay isticmaali karaan ilo makaanik bilaash ah si ay u bixiyaan ilo kale oo koronto oo loogu talagalay qaybaha elektiroonigga ah ee isticmaala tamarta yar.Nooca walxaha iyo qaab-dhismeedka aaladda ayaa ah halbeegyada muhiimka ah ee soo saarista aaladaha taabashada ee ku saleysan isku xirka korantada.Marka lagu daro walxo aan dabiici ahayn oo koronto ah, qalabka dabiiciga ah ee jilicsan ayaa sidoo kale lagu sahamiyay aaladaha xiran.
Polymers-ka lagu farsameeyo nanofiber-yada hababka korantada ayaa si weyn loogu isticmaalaa agabka kaydinta tamarta piezoelectric.Piezoelectric polymer nanofibers waxay fududeeyaan abuurista qaababka naqshadaynta dharka ku salaysan ee codsiyada la gashan karo iyadoo la siinayo jiilka elektiroonigga ah ee ku salaysan dabacsanaanta farsamada ee degaanno kala duwan.
Ujeedadaas awgeed, polymers piezoelectric ayaa si ballaaran loo isticmaalaa, oo ay ku jiraan PVDF iyo kuwa ka soo jeeda, kuwaas oo leh piezoelectricity xooggan.Fiilooyinka PVDF waa la sawiray oo lagu miiqayaa maro loogu talagalay codsiyada piezoelectric oo ay ku jiraan dareemayaasha iyo koronto-dhaliyeyaasha.

Shaqada hadda jirta, koronto-dhaliyeyaasha dharka ee ku salaysan PVDF nanofiber filaments ayaa la dhisay iyadoo la adeegsanayo habka 50-jet ee elektiroonigga ah ee isdaba-joogga ah, halkaas oo isticmaalka 50 nozzles ay fududeyso soo saarista nanofiber suunka iyadoo la adeegsanayo suunka wareejinta suunka wareega.Qaabab tolmo oo kala duwan ayaa la sameeyay iyadoo la isticmaalayo dunta PET, oo ay ku jiraan 1/1 (caado), 2/2 iyo 3/3 feeraha weft.
Shaqadii hore ayaa ka warbixisay isticmaalka naxaasta ee isku xidhka fiber-ka ee qaabka fiilooyinka naxaasta ah ee isku toosan ee durbaanka ururinta fiber-ka.Si kastaba ha noqotee, shaqada hadda jirta waxay ka kooban tahay ulo naxaas ah oo isbarbar socda oo u dhexeeya 1.5 cm marka loo eego suunka gudbinta si ay u caawiso isku toosinta lafdhabarta ee ku saleysan isdhexgalka elektrostatic ee u dhexeeya fiilooyinka soo dallacay iyo kharashyada dusha sare ee fiilooyinka ku xiran fiilada naxaasta ah.
Si ka duwan sida hore loogu sharraxay dareemayaasha awoodda ama piezoresistive, dareemaha cadaadiska unugyada ee lagu soo jeediyay warqaddan ayaa ka jawaabaya tiro balaadhan oo ah xoogagga wax gelinta laga bilaabo 0.02 ilaa 694 Newtons.Intaa waxaa dheer, dareemaha cadaadiska dharka ee la soo jeediyay ayaa xajistay 81.3% gelinta asalka ah ka dib shan dhaqid oo caadi ah, taas oo muujinaysa adkaysiga dareenka cadaadiska.
Intaa waxaa dheer, qiyamka dareenka ee qiimeynaya danab iyo natiijooyinka hadda jira ee 1/1, 2/2, iyo 3/3 feeraha feeraha ayaa muujiyay dareenka sare ee 83 iyo 36 mV / N ilaa 2/2 iyo 3/3 cadaadiska feeraha.3 dareemayaasha weft waxay muujiyeen 245% iyo 50% dareenka sare ee dareemayaasha cadaadiska, siday u kala horreeyaan, marka la barbardhigo 24 mV / N dareenka cadaadiska weft 1/1.

Gebogebadii, daraasaddan waxay muujinaysaa dareemaha cadaadiska unugyada oo aad u nugul oo xiran oo ay ku jiraan PVDF nanofiber piezoelectric filaments.Dareemayaasha cadaadiska la soo saaray ayaa leh tiro balaadhan oo ah xoog wax galinta laga bilaabo 0.02 ilaa 694 Newtons.
Konton nozzles ayaa loo adeegsaday hal nooc oo ah mishiinka wareeg ee korantada, iyo derin joogto ah oo nanofibers ah ayaa la soo saaray iyada oo la adeegsanayo qalab qaade dufcad ah oo ku salaysan ulo naxaas ah.Isku-buufinta kala-guurka ah, dharka 2/2 ee la soo saaray ayaa muujiyay dareenka 83 mV/N, kaas oo qiyaastii 245% ka sarreeya 1/1 dharka cirifka.
Dareemayaasha cadaadiska tolanka ah ee la soo jeediyay ayaa isha ku haya calaamadaha korantada iyaga oo u gudbinaya dhaqdhaqaaq jireed, oo ay ku jiraan leexinta, foorarsiga, tuujin, orodka iyo socodka.Intaa waxaa dheer, cabbirada cadaadiska dharkan waxay la mid yihiin dharka caadiga ah marka loo eego cimri dhererka, ilaalinta qiyaastii 81.3% dhalashadooda asalka ah xitaa ka dib 5 dhaqidda caadiga ah.Intaa waxaa dheer, dareemaha unugyada la soo saaray ayaa wax ku ool u ah nidaamka daryeelka caafimaadka iyadoo la dhalinayo calaamadaha korantada ee ku salaysan qaybaha joogtada ah ee socodka qofka.
