Sisebenzisa amakhukhi ukuthuthukisa okuhlangenwe nakho kwakho. Ngokuqhubeka nokuphequlula le sayithi, uyavuma ukusetshenziswa kwethu kwamakhukhi. Ulwazi Olwengeziwe.
Izinzwa zengcindezi ezigqokekayo zingasiza ukuqapha impilo yabantu futhi ziqaphele ukusebenzisana kwekhompyutha. Imizamo iyaqhubeka ukudala izinzwa zokucindezela ngomklamo wedivayisi yendawo yonke kanye nokuzwela okuphezulu ekucindezelweni kwemishini.
ISIFUNDO: Weave iphethini ethelelekile ye-Textile Piezoelectric ingcindezi ye-transduler esekelwe ku-ElectroSpan Polyvinylidene Ama-Nanofibers anama-nozzles angama-50. Isikweletu sesithombe: Isitudiyo sase-Afrika / Shutterstock.com
Isihloko esishicilelwe kwiphephabhuku i-NPJ Flexible Electronics sibika nge-Piezoelectric tsress tress transcurications for izindwangu zisebenzisa i-polyethylene terephthalate (Peldfylidene Fluoride (PVDF) WEFT YARNS. Ukusebenza kwenzwa yengcindezi ethuthukisiwe maqondana nokulinganisa kwengcindezelo kususelwa kuphethini we-weave kuboniswa esikalini sendwangu cishe amamitha ayi-2.
Imiphumela ikhombisa ukuthi ukuzwela kwe-sensor yengcindezelo kwenziwe kahle kusetshenziswa ukwakheka kweCanard kungu-245% ophakeme kunalokho kwe-1/11 Canard Design. Ngaphezu kwalokho, kusetshenziswe okokufaka okuhlukahlukene ukuhlola ukusebenza kwezindwangu ezilungiselelwe, kufaka phakathi ukuguquguquka, ukuncipha, ukugoqa, ukusonteka, kanye nokunyakaza kwabantu okuhlukahlukene. Kulomsebenzi, inzwa yengcindezi esekelwe ekufuneni nge-sensor Pixel ekhombisa izici eziqinile zemiqondo kanye nokuzwela okuphezulu.
Ilayisi. 1. Ukulungiselela imicu ye-PVDF nezindwangu eziningi. Umdwebo wenqubo ye-elecyzzline ye-elecyzzle esetshenziselwa ukukhiqiza ama-mats aqondaniswe ama-pvdf nanofibers, lapho kufakwa khona izinduku zethuli ebhande elihambisanayo, futhi izinyathelo ukulungiselela izinhlaka ezintathu ezinama-monofilament ezivela kuma-monofilament ama-monofilament amane. Isithombe se-B sem kanye nokusatshalaliswa kobubanzi bemicu ye-PVDF eqondanisiwe. C sem isithombe sentambo yeply ene. d amandla ashukumisayo kanye nobunzima ekhefu le-khefu le-ply ezine njengomsebenzi wokusonta. I-X-ray diffraction iphethini yentambo ye-Ply ene-Ply ekhombisa ukuba khona kwezigaba ze-Alpha neBeta. © Kim, DB, Han, J., Sung, SM, KIM, MS, Choi, BK, Park, SJ, Hong, H. R et al. (2022)
Ukuthuthukiswa okusheshayo kwamarobhothi ahlakaniphile kanye namadivayisi we-elekthronikhi agqokekayo anikeze amadivaysi amaningi amasha asuselwa ezinzwa eziguquguqukayo, kanye nezinhlelo zawo kuma-elekthronikhi, embonini, kanye nemithi ikhula ngokushesha.
I-PiezoelectricIty yinkokhelo kagesi eyenziwe ngezinto ezibonakalayo ezihambisana nengcindezi yemishini. I-Piezoelectriction ezintweni ezisetshenziswayo ze-asymmetric ivumela ubudlelwano obuhle obuguqulwa obuqondile phakathi kwengcindezi yemishini kanye necala likagesi. Ngakho-ke, lapho ucezu lwe-piezoelectric lukhubazekile ngokomzimba, kudalwe icala kagesi, futhi okuphambene nalokho.
Amadivaysi ePiezoelectric angasebenzisa umthombo wamahhala wemishini ukuhlinzeka ngemithombo yamandla ahlukile yezinto ze-elekthronikhi ezidla amandla amancane. Uhlobo lwezinto ezibonakalayo nokwakheka kwensiza kungamapharamitha asemqoka ukukhiqizwa kwamadivayisi okuthinta asuselwa ku-elektromomechanic coupling. Ngaphezu kwezinto eziphakeme ze-Inorgage Inorganic, izinto eziguquguqukayo eziguquguqukayo nazo zihlolisisiwe kumadivayisi agqokekayo.
Ama-polymers acutshungulwe abe ngama-nanofibers ngezindlela ze-electrospinning asetshenziswa kabanzi njengamadivayisi wokugcina amandla we-piezoelectric. I-Piezoelectric polymer nanofibers yenzale ukwakhiwa kwezakhiwo zezokwakhiwa zendwangu ezisetshenziselwa ukugqokwa ngokuhlinzeka nge-electromechanical GENERATION kususelwa ekugqekezweni kwemishini ezindaweni ezahlukahlukene.
Ngale njongo, ama-polymers we-piezoelectric asetshenziswa kabanzi, kufaka phakathi i-PVDF kanye nokutholakala kwayo, okunama-piezoelectricicity aqinile. Le micu ye-PVDF idonswa futhi ihlelwe ngezindwangu zohlelo lokusebenza lwePiezoelectric kufaka phakathi izinzwa nama-generator.
Umdwebo 2. Izicubu zendawo enkulu kanye nezakhiwo zazo ezibonakalayo. Izithombe zephethini enkulu ye-2/2 yeft kuze kube ngu-195 cm 50 cm cm. isithombe se-B sem yephethini ye-2/2 yeft equkethe i-PVDF WEEFT eyodwa exhunywe ngezisekelo ezimbili zezilwane zasekhaya. C modulus kanye ne-strain ekhefu ngezindwangu ezahlukahlukene nge-1/11, 2/2 ne-3/3 yeft Edges. d yi-angle yokulengisa ekalwa ngendwangu. © Kim, DB, Han, J., Sung, SM, KIM, MS, Choi, BK, Park, SJ, Hong, H. R et al. (2022)
Emsebenzini wamanje, ama-generator endwangu asuselwa kuma-pollaments we-PVDF Nanofiber ayakhiwa kusetshenziswa inqubo yokulandelana kwe-50-jet ye-50-Jet, lapho ukusetshenziswa kwama-nozzles angama-50 kusiza ukukhiqizwa kwama-nanofiber mat asebenzisa ibhande elijikelezayo le-nanofiber esebenzisa ibhande elijikelezayo le-nanofiber esebenzisa ibhande le-nanofiber lisebenzisa ibhande elijikelezayo le-nanofiber esebenzisa ibhande elijikelezayo le-nanofiber esebenzisa ibhande elijikelezayo lebhande. Izakhiwo ezahlukahlukene ze-weave zenziwa kusetshenziswa i-pet yorn, kufaka phakathi i-1/11 (ithafa), 2/2 kanye nama-3/3 we-weft.
Umsebenzi owedlule ubike ukuthi ukusetshenziswa kwe-Copper yokuqondanisa kwe-fiber ngendlela ye-adigned Copper izintambo ngezigubhu zokuqoqwa kwe-fiber. Kodwa-ke, umsebenzi wamanje uqukethe izinduku zethu zethusi zethusi ezihlukaniswe ngo-1.5 cm ngebhande lokuhambisa ukusiza ukuvumelanisa ama-spinneres asuselwa ekuxhumaneni kwama-elektrostiki phakathi kwemicu ye-angenayo enamathiselwe kwi-fiber yethusi.
Ngokungafani nezinzwa ezichazwe ngaphambilini noma izinzwa zePiezoresures, inzwa yokucindezela kwezicubu ezihlongozwayo kuleli phepha liphendula amabutho anhlobonhlobo wokufaka kusuka ku-0.02 kuye ku-694 Newtons. Ngaphezu kwalokho, inzwa yendwangu ehlongozwayo egcinwe i-81.3% yokufaka kwayo kwasekuqaleni ngemuva kokugeza okujwayelekile okuyisihlanu, okubonisa ukuqina kwenzwa yengculazi.
Ngaphezu kwalokho, amanani wokuzwela ukuhlaziya ama-voltage kanye nemiphumela yamanje ye-1/11, 2/2, futhi i-3/3 Izinzwa ezi-3 ze-weft zikhombise ama-245% no-50% ukuzwela okuphezulu kwalezi zinzwa ezicindezelayo, ngokulandelana, uma kuqhathaniswa ne-24 mv / n weft pressure sensor 1/1.
Ilayisi. 3. Ukusetshenziswa okunwetshiwe kwenzwa ye-Full-acpep Pressure Pressure. Isibonelo sezinzwa zengcindezi ye-insole eyenziwe ngendwangu engu-2/2 ye-weft ribbed ifakwe ngaphansi kwama-electrove endilinga amabili ukuthola i-forefoot (ngezansi nje kwezinzwane) nokunyakaza kwesithende. B Ukumelwa kwesikimu kwe-B esiteji ngasinye sezinyathelo ngazinye enqubweni yokuhamba: Isithende Ukufika, Kusisekelo, Ukutholwa Kwezinzwane Nokuxhumana Ngomlenze. C ama-voltage akhipha amasiginali ephendula ingxenye ngayinye yesinyathelo se-gait sokuhlaziywa kwe-gait kanye nezimpawu zikagesi ezenziwe ngogesi ezihambisana nesigaba ngasinye se-gait. E Schematic of a fun izicubu inzwa yokucindezela okugcwele ngamaseli afinyelela kuma-pixel angamaxande ayi-12 anemigqa evuthayo ephethe amasignali ngasinye. f Imephu ye-3D yesiginali kagesi ekhiqizwa ngokucindezela umunwe ku-pixel ngayinye. g Isiginali kagesi sitholwa kuphela ku-pixel ecindezelwe ngomunwe, futhi akukho sibonakaliso esiseceleni esikhiqizwa kwamanye amaphikseli, okuqinisekisa ukuthi akukho crosstalk. © Kim, DB, Han, J., Sung, SM, KIM, MS, Choi, BK, Park, SJ, Hong, H. R et al. (2022)
Ekuphetheni, lolu cwaningo lukhombisa inzwa ebucayi kakhulu futhi egqoke izicubu zokucindezela izicubu ezifaka ama-pvdf nanofiber piezoelectric filaments. Izinzwa zengcindezi ezikhiqizwayo zinamabutho ahlukahlukene wokufaka kusuka ku-0.02 kuye ku-694 Newtons.
Kwasetshenziswa ama-nozzles womshini owodwa wokuphothama-kagesi we-prototype, futhi i-mat eqhubekayo yama-nanofibers yakhiqizwa kusetshenziswa i-batch conveyor esekelwe ezinkulumweni zethusi. Ngaphansi kokucindezelwa okwenziwe ngezikhathi ezithile, indwangu ye-2/2 yeft ye-WEFT ikhombisa ukuzwela kuka-83 mv / n, okungama-245% indwangu ye-1/11 ye-weft hem.
Izinzwa zengcindezi ezihlongozwayo zonke ezihlongozwayo zibheka amasiginali kagesi ngokuwahambisa ekunyakazeni ngokomzimba, kufaka phakathi ukusonteka, ukugoqa, ukuncipha, ukushefa, ukugijima nokuhamba. Ngaphezu kwalokho, lawa ma-gastric tressres ama-gauge aqhathaniswa nezindwangu ezijwayelekile ngokwemibandela yokuqina, ukugcina cishe ama-81.3% wesivuno sawo sokuqala ngisho nangemva kokugeza okujwayelekile okungu-5. Ngaphezu kwalokho, inzwa yezicubu ezenziwe ngempumelelo ezinhlelweni zezempilo ngokwakha amasiginali kagesi asuselwa ezingxenyeni eziqhubekayo zokuhamba komuntu okuqhubekayo.
