Iko kuenderera mberi kwekuvandudzwa kwefiber tekinoroji kwaita kuti zvikwanise kuongorora huwandu hwakawanda hwekushandiswa kwemachira echinyakare. Muchisikigo, mafiibha anowanzoita basa mukuparadzira ruzha. Muchirongwa chekuongorora kwevanhu, semuenzaniso, eardrum, iyo inokonzera kugadzirisa kusawirirana kweacoustic impedance pakati pemhepo munzeve yenzeve uye mvura iri munzeve yemukati, inoitika kuti yakagadzirwa nepamusoro-modulus fibers. Dura renzeve rinoshandura tsinhiro yenzwi kuita ma mechanical vibrations ari mumapfupa epakati nzeve, ayo anobva aendeswa kucochlea munzeve yomukati. Mucochlea, fiber-senge bvudzi bundles inotsauka, inozopedzisira yashandura ma mechanic vibrations kuita masaini emagetsi anogamuchirwa netsinga system.

Afemerwa nemaitiro ekuitisa iyo odhiyo system inoshandura kudzvanywa kwemutsindo kuita ma mechanic vibrations, uyezve mechanic vibrations kuita masaini emagetsi, uye kukosha kwefibers muodhiyo system, timu yaProfessor Yoel Fink kuMIT yakagadzira acoustic fabric. Kusiyana neakaomesesa matatu-dimensional chimiro cheauditory system, jira rakati sandara, rine jira rematrix rine fiber sensors dzakarukwa mariri. Iyo jira matrix inokwanisa kunyatso shandura kudzvinyirirwa kweruzha kuita mechaniki vibrations senge eardrum, uye iyo fiber sensor inogona kushandura ma mechanical vibrations kuita masaini emagetsi senge cochlea.

Inowanikwa kuti iyo deformation simba inogadzirwa ne mechanical vibration inogona kuiswa uye kugoverwa mu fiber core zvakanaka. Iyo asymmetric chimiro chefiber inobvumira iyo fiber kuti ibudise yakakura dhizaini panguva ye deformation. Naizvozvo, timu yekutsvagisa yakashandisa tekinoroji yekudhirowa yakavakirwa pakugadzirwa kwefiber kugadzira huwandu hukuru hwemafiber akaumbwa nezvinhu zvitanhatu zve sensor, kusanganisira musimboti unoumbwa neP(VDF-TrFe) uye barium piezoelectric titanate (BaTiO3) ceramic particles, an electrode inoumbwa ne nano carbon powder uye polyethylene, copper waya electrode, uye SEBS elastomer.

Kuti tigadzirire machira anonzwika acoustic, takagadzira jira rakarukwa rine shinda yekotoni (warp) uye yakakwirira modulus Twaron filament (weft), uye ipapo zvakananga dzakarukwa kupisa-kudhonzwa faibha kupinda jira substrate, sekutonga yakachena donje jira rakaenzana saizi. Pakupedzisira, zvakaonekwa kuti acoustic mhinduro yeTwaron / donje jira raive rakakwirira kudarika rejira redonje rakachena. Panguva imwecheteyo frequency, jira reTwaron / donje raive neyakaodha meshini vibration modhi, iyo yakakurudzira iyo fiber kuburitsa yakakwira vibration amplitude uye kubhenda deformation munzira imwe chete. Uyezve, mushure memazuva gumi ekugeza muchina, iwo magetsi uye acoustic zvimiro zvinogona kuramba zvichichengetwa.

Yakarukwa jira reTwaron/cotton acoustic muchipfeko chinonyatso cherechedza kwakananga kunobva ruzha. Kutarisisa kwakanangana kwenzvimbo dzine ruzha kunogona kubatsira zvakanyanya kune vanhu vakapfeka zvinoyamura kunzwa, vachivimbisa kubvisa ruzha rwekumashure ivo vachivabvumira kunzwa manzwi chete kune kwakanangana, pamwe nevemutemo vachitsvaga kwaibva pfuti. Uye zvakare, mumunda webiomedicine, chipfeko chinogona kushanda se stethoscope, ichipa mhinduro nyowani yekugadzikana, inoenderera, chaiyo-nguva uye yenguva refu yekutarisa moyo wemunhu uye hutano hwekufema.

Pamusoro pekunzwa ruzha, jira rinogonawo kuridza zvinonzwika. Idzi hembe mbiri dzinogonesa bidirectional acoustic kutaurirana, ine inofananidzwa nguva domain waveform uye frequency spectrum pakati pekutaura uye kugamuchirwa. Izvi zvinobatsira pakuzadzikiswa kwekutaurirana kwemunhu-kune-munhu, uye zvine tarisiro yakanaka yekushandisa kune matsi kana vanhu vakaoma vanonzwa, kutaurirana kwakavanzika, uye kunyangwe kutaurirana pasi pemvura.
