Izinkinga zokulalela? Beka ihembe lakho. Umbiko wokucwaninga oshicilelwe yiBritish Journal Imvelo emnyakeni engu-16 ibike ukuthi indwangu equkethe imicu ekhethekile ingathola kahle umsindo. Iphefumlelwe uhlelo oluyindida lwezindlebe zethu, leli ndwangu lingasetshenziswa ukwenza ukuxhumana kwezindlela ezimbili, lisize ukulalela okuqondisayo, noma ukuqapha umsebenzi wenhliziyo.
Ngokuyinhloko, zonke izindwangu zidlidliza ukuphendula imisindo ezwakalayo, kepha lezi zinvundla ziyizilinganiso ze-nano, ngoba zincane kakhulu ukuba zibonakale. Uma sithuthukisa izindwangu ezingathola futhi zicubungule umsindo, kulindeleke ukuthi zivule inani elikhulu lezicelo ezingokoqobo ezivela ezindwangu zekhompyutha ziye ekuvikelekeni bese kuthi i-biomedicine.
Ithimba lokucwaninga nge-MIT lichaze ukwakheka okusha kwalesi sikhathi. Iphefumlelwe ukwakheka okuyinkimbinkimbi kwendlebe, le ndwangu ingasebenza njengemakrofoni ebucayi. Indlebe yomuntu ivumela ukudlidliza kukhiqizwe umsindo ozoguqulwa ube amasiginali kagesi nge-cochlea. Lolu hlobo lokuklama ludinga ukwehlisa indwangu ekhethekile kagesi - i-piezoelectric fiber kwindwangu yendwangu, engaguqula igagasi lokucindezela lemvamisa elizwakalayo libe vemvane elibonakalayo lokudlidliza. Le fiber ingaguqula la ma-vibrations emishini abe yizimpawu zikagesi, ezifanayo nomsebenzi we-cochlea. Imali encane kuphela yale fiber ekhethekile ye-piezoelectric ingenza indwangu izwakale ibucayi: I-fiber ingenza imakrofoni eyi-fiber yamamitha-skwele amaningi.
Imakrofoni ye-fiber ingabona amasignali azwakalayo abuthakathaka njengenkulumo yabantu; Lapho ilukiwe ekulweni kwehembe, indwangu ingabona izici zokushaya kwenhliziyo ezicashile zabagqokile; Kuyathakazelisa kakhulu, le fiber nayo ingaba umshini wokuwasha futhi inokuwala, okwenza kube yikhethelo elihle lezicelo ezigqokekayo.
Ithimba lokucwaninga labonisa ukusetshenziswa kwezicelo ezintathu eziphambili zale ndwangu lapho zifakwa kumahembe. Izingubo zingathola ukuqondiswa kokukhala okushayayo; Kungakhuthaza ukuxhumana kwezindlela ezimbili phakathi kwabantu ababili - bobabili bagqoka le ndwangu engabona umsindo; Lapho indwangu ithinta isikhumba, ingabheka futhi inhliziyo. Bakholelwa ukuthi lo mklamo omusha ungasetshenziswa ezimweni ezahlukahlukene, kufaka phakathi ukuphepha (njengokuthola umthombo wesibhamu), ukulalela okuqondiswa kweziguli zokulwa neziguli ezinakekela izinhliziyo nezifo zokuphefumula.
