Ngokunyuka kobukrelekrele bokwenziwa, abaphandi baseMntla Melika naseYurophu baye benza inkqubela encomekayo kuphando nophuhliso lokuvuselelwa kwezonyango.Phakathi kwazo, iiprostheses ezenziwe ngobukrelekrele (iiprothesi zerobhothi) ziye zatsala ingqalelo enkulu.Enye yezinto eziphambili ze-AI prostheses yiyunithi yokulawula amandla.Iprothesisi yesintu ixhasa lowo uyisebenzisayo ngendlela emiselweyo, ngoko ke amanye amalungu omzimba kunye namalungu omzimba adla ngokufuna ukusebenzisana neprosthesis eqinile ukuze agqibezele isenzo.Akunjalo kuphela ukukwazi ukuhamba okulinganiselwe, kodwa kunye nokuhamba akuhambelani.Kulula ukuwa kunye nokuphuhlisa iingxaki zesibini, ukudala ubunzima obuninzi kunye nemingeni kwizigulane.Ukwahluke kwi-prosthetics yendabuko, i-robotic prosthetics inokubonelela abasebenzisi ngenkxaso esebenzayo kunokuba i-passive balance balance ngokweenguqu zeemeko zendlela kunye nokunyakaza, okubavumela ukuba benze ngokukhululekileyo kwaye baphucule umgangatho wabo wobomi kakhulu.

Ngokwezibalo, kukho ubuncinane i-300,000 yabantu abanqunyulwe imilenze e-US.ETshayina, kukho abantu abazizigidi ezingama-24.12 abakhubazekileyo ngokwasemzimbeni, yaye abazizigidi ezisisi-2.26 kubo banqunyulwe imilenze, yaye ngama-39.8 ekhulwini kuphela abaye bafakelwa amayeza okufakelwa.Ubalo lwale minyaka mibini idlulileyo lubonisa ukuba eTshayina umlinganiselo wonyaka wokunqunyulwa kwamalungu amatsha umalunga nama-200,000 ngenxa yeengozi zendlela, iingozi zemizi-mveliso, iingozi zasemigodini nezifo.Inani lokunqunyulwa kwamalungu ngenxa yesifo seswekile likhula ngokukhawuleza.Amalungu afakelweyo nawo kufuneka atshintshwe njengoko ekhula.Ukongezelela, izigulane ezinobuthakathaka bemisipha, i-muscle atrophy, okanye i-hemiplegia nazo zifuna izixhobo zonyango ezifana ne-exoskeletons ukubanceda ukuba bame okanye bahambe kwakhona.Ke ngoko, iiprosthetics ezisebenzayo nezithembekileyo kunye nee-exoskeleton ezihlakaniphile zinemfuno enkulu yentengiso kunye nokubaluleka kwentlalo.

Ukuqaphela ukulawulwa kwamandla e-prosthetics ehlakaniphile, i-6 DOF i-sensor yamandla iyadingeka ukuva utshintsho kwiimeko zendlela ngexesha langempela kunye nokulawula ngokuchanekileyo ubukhulu bamandla.Ubunzima beemeko zendlela, ukuhlukahluka kwezenzo kunye nezithintelo zokudibanisa zibeka iimfuno eziphezulu kakhulu kwi-6 DOF force sensors.Akufunekanga nje ukuba ihlangabezane neemfuno zoluhlu lwamandla kunye nomzuzu, kodwa ibe yikhaphukhaphu kwaye incinci.Abasebenzisi bathi emva kophando, bafumanisa ukuba, kwimarike, kuphela i-SRI M35 i-ultra-thin series 6 DOF force sensors inokuhlangabezana nazo zonke ezi mfuno.
Uluhlu lwe-M35 lubandakanya iimodeli ezili-18, zonke zingaphantsi kwe-1cm ubukhulu, kwaye incinci i-7.5mm kuphela ubukhulu.Ubunzima bonke bungaphantsi kwe-0.26kg, kwaye eyona ilula yi-0.01kg kuphela.I-non-linearity kunye ne-hysteresis yi-1%, i-crosstalk engaphantsi kwe-3% kwaye yakhiwe ngokubiwa kwi-metal foil strain gauge technology.Ukusebenza okugqwesileyo kwezi zinzwa zincinci, zilula, zixineneyo zinokufezekiswa ngenxa yeminyaka engama-30 yoyilo lwamava e-SRI, evela kwidummy yokhuseleko lwemoto kunye nokwanda ngaphaya.Ezi teknoloji ngoku zisetyenziswa kuphando kunye nophuhliso lweeprothetics ezikrelekrele ukukhapha ukhuseleko lwabantu abaninzi.

Ngaphandle koko, ixabiso leenzwa ze-SRI likhuphisana kakhulu xa lithelekisa nezo zivela kwabanye abavelisi abakhulu bezoluvo.Ngamandla ayo obugcisa obuqinileyo kunye nexabiso elifikelelekayo, uphawu olusezantsi lwe-SRI luye lwasasazwa ngomlomo kwaye luthandwa kakhulu ziilebhu zophando zokuvuselela unyango kunye noshishino lwe-robotic prosthetics.Kwiminyaka eyi-7 edlulileyo, abaphandi be-bionics kunye ne-biomechanics kunye neenjineli ezivela e-United States, e-China, eKhanada, eJapan, e-Itali, eSpain nakwamanye amazwe baye basebenzisa i-SRI ultra-thin sensors kuphando olutsha, bapapashe inani elikhulu lamaphepha emfundo kwaye baphumelele ngokuphawulekayo. inkqubela.
Kwinqaku elilandelayo, siya kwazisa ukusetyenziswa kwe-SRI M35 i-ultra-thin series kwintsimi yokuvuselela unyango.Kubandakanya iziphumo zophando zamva nje zeprosthetics ezikrelekrele kunye ne-exoskeletons ezikrelekrele ezipapashwe kwiNdalo kunye neejenali zenkomfa ye-IEEE.Hla umamele!
