Nekukwira kwehungwaru hwekugadzira, vaongorori muNorth America neEurope vakaita fambiro mberi inokatyamadza mukutsvagisa nekuvandudza kwezvekurapa.Pakati pawo, maprostheses akangwara ekugadzira (robhoti prostheses) akakwezva vanhu vakawanda.Chimwe chezvinhu zvakakosha zveAI prostheses isimba rekudzora unit.Prosthesis yechinyakare inotsigira mushandisi nenzira yakamisikidzwa, saka dzimwe nhengo dzemushandisi nenhengo dzemuviri dzinowanzoda kushandira pamwe neiyo yakaoma prosthesis kupedzisa chiito.Kwete chete kugona kufamba kwakaganhurirwa, asiwo kufamba hakuna kurongeka.Zviri nyore kudonha uye kugadzira zvechipiri matambudziko, zvichigadzira mamwe matambudziko uye matambudziko kune varwere.Yakasiyana neyakajairwa prosthetics, marobhoti prosthetics anogona kupa vashandisi basa rinoshanda kwete kungoita chiyero chetsigiro zvinoenderana nekuchinja kwemamiriro emugwagwa uye mafambiro, zvichivabvumira kuita zvakasununguka uye kuvandudza hupenyu hwavo zvakanyanya.

Zvinoenderana nenhamba, kune vanosvika zviuru mazana matatu vakadimurwa mitezo muUS.KuChina, kune vanhu 24.12 miriyoni vakaremara mumuviri, avo 2.26 miriyoni vakadimburwa makumbo, uye 39.8% chete vakaiswa mishonga yekunamatira.Huwandu hwemakore maviri adarika hunoratidza kuti kuChina avhareji yenhamba yevatsva vanodimburwa paavhareji inosvika zviuru mazana maviri nekuda kwetsaona dzemotokari, tsaona dzemumaindasitiri, tsaona dzemumigodhi nezvirwere.Nhamba yevanodimburwa nhengo nekuda kwechirwere cheshuga iri kuwedzera nekukurumidza.Nhengo dzeprosthetic dzinodawo kutsiviwa sezvavanokura.Mukuwedzera, varwere vane kushaya simba kwemhasuru, muscle atrophy, kana hemiplegia vanodawo rubatsiro rwezvechiremba se exoskeletons kuti vabatsire kumira kana kufamba zvakare.Naizvozvo, anoshanda uye akavimbika akangwara prosthetics uye akangwara exoskeletons ane yakakura kudiwa kwemusika uye kukosha munharaunda.

Kuti uone simba rekutonga kweakangwara prosthetics, 6 DOF simba sensors inodiwa kuti unzwe shanduko yemamiriro emugwagwa munguva chaiyo uye kunyatso kudzora ukuru hwesimba.Kuoma kwemamiriro emugwagwa, kusiyanisa kwezviito uye zvipingamupinyi zvekubatanidza zvinoisa zvakanyanya zvinodiwa pa6 DOF simba sensors.Kwete chete inofanira kusangana nemhando yezvinodiwa zvesimba uye nguva, asiwo kuve yakareruka uye yakatetepa.Vashandisi vakati mushure mekuferefeta, vakawana kuti, pamusika, chete SRI M35 yekupedzisira-yakaonda yakatevedzana 6 DOF simba sensors inogona kusangana zvese izvi zvinodiwa.
Iyo M35 yakatevedzana inosanganisira gumi nemasere modhi, ese ari pasi pe1cm gobvu, uye diki ingori 7.5mm gobvu.Huremu ese ari pasi pe 0.26kg, uye akareruka ndeye 0.01kg chete.Non-linearity uye hysteresis i1%, crosstalk isingasviki 3% uye inovakwa nekuba pasimbi foil strain gauge tekinoroji.Kuita kwakanakisa kweaya matete, akareruka, macompact sensors anogona kuwanikwa nekuda kwemakumi matatu emakore ehunyanzvi hwekugadzira yeSRI, kubva kumota yekuchengetedza tsaona dummy uye kuwedzera kupfuura.Aya matekinoroji ave kushandiswa mukutsvagisa nekuvandudza kweakangwara prosthetics kuperekedza kuchengetedzeka kwevanhu vazhinji.

Kunze kwezvo, mutengo weSRI sensors unokwikwidza zvakanyanya uchienzaniswa neaya kubva kune mamwe makuru emagetsi sensor vagadziri.Nesimba rayo rakasimba rehunyanzvi uye mutengo unokwanisika, iyo yakaderera-kiyi SRI mhando yakaparadzirwa neshoko remuromo uye inodiwa zvakanyanya nepamusoro ekurapa kuvandudza marabhoritari ekutsvagisa uye robhoti prosthetics indasitiri.Mumakore manomwe apfuura, bionics uye biomechanics vaongorori uye mainjiniya kubva kuUnited States, China, Canada, Japan, Italy, Spain nedzimwe nyika vakashandisa SRI Ultra-thin sensors patsvakiridzo itsva, vakaburitsa nhamba huru yemapepa ezvidzidzo uye vakawana zvinoshamisa. kufambira mberi.
Muchinyorwa chinotevera, tichasuma mashandisirwo eSRI M35 Ultra-mutete akatevedzana mundima yekurapa kurapwa.Kusanganisira yazvino mhedzisiro yekutsvagisa yehungwaru prosthetics uye akangwara exoskeletons akaburitswa muNature uye IEEE musangano wenhau.Ramba wakatarisa!
