Ka nts'etsopele ea mahlale le thekenoloji, lisebelisoa tsa elektroniki tse ka roaloang li sebelisoa haholo ho biomedicine le mafapheng a mang. Ka nako e ts'oanang, batho ba na le litlhoko tse phahameng ho boiketlo ba bona le bophelo ba betri. Li-ceramics tsa setso tsa piezoelectric, tse kang lead zirconate titanate (PZT), li na le tlhahiso e phahameng ea piezoelectric, empa ho satalla ho hoholo le brittleness; Le ha PVDF le li-polymer tse ling tsa piezoelectric li na le modulus e tlase, empa thepa ea tsona ea piezoelectric e fokola. Ka hona, ke tataiso ea bohlokoa ea lipatlisiso ho kopanya melemo ea bobeli ho hlahisa lisebelisoa tsa piezoelectric tse tenyetsehang.

Boemong bona, sehlopha sa lipatlisiso sa Univesithi ea Toropo ea Hong Kong se thehile lesela le feto-fetohang, le lumellehang le le phahameng le phahameng la tertiary piezoelectric ceramic composite le thehiloeng holim'a mokhoa oa sol-gel o thusitsoeng ke template, o nang le sebopeho se ikhethileng sa ka hare sa mekhahlelo e mengata se ka matlafatsang thepa ea mochini ka katleho.

Lesela la motsoako oa piezoelectric le entsoe ka PZT ceramic skeleton le P (VDF-TRFe) coating, 'me mesh ea koporo e khomaretsoe ka mahlakoreng ka bobeli e le li-electrode. Joalo ka template ea lesela e sebelisitsoeng, boemo ba submillimeter ba likhoele tse ngata tsa ceramic tse lohelletsoeng li etsa PZT skeleton ea ceramic, athe likhoele tsa PZT tsa boemo ba micron tse etsang sephutheloana sa fiber ea ceramic ke meaho ea bobeli. Filimi ea P (VDF-TrFE) e koahetsoeng ka moralo oa ceramic oa PZT e fana ka thepa e betere ea mochini le piezoelectric bakeng sa lesela le kopaneng la piezoelectric. Sebopeho se ikhethileng sa ka hare sa mekhahlelo e mengata se boetse se etsa hore lesela le be le moea o motle oa ho phunyeletsa, moea o kenang ho fihlela ho 45.1mm / s.

Ha ho bapisoa le motsoako oa setso oa piezoelectric, lesela le kopaneng la piezoelectric le na le modulus e phahameng ea Young (0.35gpa), matla a ho robeha, bolelele, boima (0.125MJ / m3) le matla a robehileng ka thepa ea mochini. Mabapi le thepa ea piezoelectric, lesela le khona ho hlahisa motlakase o bulehileng oa 128 V, o lekaneng ho khantša 75 leds ka nako e le 'ngoe.

Ho kenella ha moea le thepa ea mochini ea piezoelectric ceramic composite fiber

Ho lekola lits'ebetso tse ka bang teng tsa lesela la motsoako oa piezoelectric ho shebellisoang ho sisinyeha ha motho le pokello ea matla, bafuputsi ba e sebelisitse e le insole bakeng sa sole ea seeta ho fetola matla a hlahisoang ke ho tsamaea ha motho ka lipontšo tsa motlakase. Ha e ne e sebelisoa e le pedometer, mehato ea 63 e ile ea tlalehoa ka katleho ka hare ho 2min 'me ea bontšoa skrineng sa fono ka nako e le' ngoe. Ha e sebelisoa e le sesebelisoa sa ho kotula matla, motlakase o bolokiloeng ka capacitor o nyolohela ho 3.1V nakong ea ho hatakeloa ha 36s. Matla a bolokiloeng ka capacitor a ka sebelisoa hape ho matlafatsa mitha ea elektroniki, e ka tsoelang pele ho sebetsa bakeng sa 16s.

Patlisiso ea moralo oa lesela la piezoelectric moralo oa mekhahlelo e mengata le ho etsa mohopolo o sebetsang ho ntlafatsa thepa ea setso ea piezoelectric ea thepa ea piezoelectric e fana ka terene e ncha ea monahano, ka nako e ts'oanang, e lebisa tlhokomelo e kholo ho phefumoloho ea moea, piezoelectric, tenyetseha le botsitso mabapi le leano la ho leka-lekanya ho nts'etsapele lisebelisoa tse sebetsang ho lisebelisoa tse aparoang le ts'ebeliso ea lisebelisoa tsa elektroniki tse tenyetsehang.
