Chifukwa cha kukwera kwa luntha lochita kupanga, ofufuza ku North America ndi ku Europe apita patsogolo modabwitsa pa kafukufuku ndi chitukuko cha chithandizo chamankhwala.Pakati pawo, ma prostheses anzeru (opangidwa ndi roboti) akopa chidwi kwambiri.Chimodzi mwazinthu zazikulu za AI prostheses ndi gawo lowongolera mphamvu.Prosthesis yachikale imathandizira wogwiritsa ntchito mokhazikika, motero ziwalo zina za thupi la wogwiritsa ntchito nthawi zambiri zimafunikira kugwirizana ndi prosthesis yolimba kuti amalize kuchitapo kanthu.Sikuti kutha kusuntha kumakhala kochepa, komanso kusuntha kumakhala kosagwirizana.Ndikosavuta kugwa ndikuyambitsa zovuta zachiwiri, ndikupanga zovuta komanso zovuta kwa odwala.Mosiyana ndi ma prosthetics achikhalidwe, ma prosthetics a robot amatha kupatsa ogwiritsa ntchito chithandizo chokhazikika m'malo mongoyang'ana molingana ndi kusintha kwa misewu ndi mayendedwe, kuwalola kuchita momasuka ndikuwongolera moyo wawo kwambiri.

Malinga ndi ziwerengero, pali anthu osachepera 300,000 odulidwa ziwalo ku US.Ku China, kuli anthu olumala okwana 24.12 miliyoni, omwe 2.26 miliyoni ndi odulidwa ziwalo, ndipo 39.8% okha ndi omwe aikidwa zida zopangira opaleshoni.Ziŵerengero za m’zaka ziwiri zapitazi zikusonyeza kuti ku China chiŵerengero cha pachaka cha anthu odulidwa atsopano ndi pafupifupi 200,000 chifukwa cha ngozi zapamsewu, ngozi za m’mafakitale, ngozi za m’migodi ndi matenda.Chiwerengero cha anthu odulidwa ziwalo chifukwa cha matenda a shuga chikuchulukirachulukira.Ziwalo zopangira opaleshoni zimafunikanso kusinthidwa zikamakula.Kuonjezera apo, odwala omwe ali ndi zofooka za minofu, atrophy ya minofu, kapena hemiplegia amafunikanso chithandizo chamankhwala monga ma exoskeletons kuti awathandize kuima kapena kusuntha kachiwiri.Chifukwa chake, ma prosthetics odalirika komanso odalirika anzeru komanso ma exoskeleton anzeru ali ndi kufunikira kwakukulu kwa msika komanso kufunika kwa anthu.

Kuti muzindikire kuwongolera kwamphamvu kwa ma prosthetics anzeru, masensa 6 a DOF amafunikira kuti azindikire kusintha kwa misewu munthawi yeniyeni ndikuwongolera ndendende kukula kwa mphamvuyo.Kuvuta kwa misewu, kusiyanasiyana kwa zochita ndi zoletsa zophatikizira zimayika zofunikira kwambiri pa masensa 6 a DOF.Osati kokha kuti akwaniritse zofunikira zosiyanasiyana za mphamvu ndi mphindi, komanso kukhala wopepuka komanso woonda.Ogwiritsa ntchito adanena kuti atatha kufufuza, adapeza kuti, pamsika, SRI M35 yokhayo yowonjezereka kwambiri ya 6 DOF mphamvu masensa amatha kukwaniritsa zofunikira zonsezi.
Mndandanda wa M35 umaphatikizapo mitundu 18, yonse yomwe ili yocheperapo 1cm, ndipo yaying'ono kwambiri ndi 7.5mm yakuda.Zolemera zonse ndi zosakwana 0.26kg, ndipo zopepuka ndi 0.01kg yokha.Non-linearity ndi hysteresis ndi 1%, crosstalk zosakwana 3% ndipo amamangidwa ndi kuba paukadaulo wazitsulo wazitsulo.Kuchita bwino kwambiri kwa masensa owonda, opepuka, ophatikizikawa amatha kutheka chifukwa cha zaka 30 za luso la SRI, lochokera ku ngozi yachitetezo chagalimoto ndikukulirakulira kupitilira.Umisiri umenewu tsopano ukugwiritsidwa ntchito pofufuza ndi kupanga ma prosthetics anzeru kuperekeza chitetezo cha anthu ambiri.

Kupatula apo, mtengo wa masensa a SRI ndiwopikisana kwambiri poyerekeza ndi omwe amachokera kwa opanga ma sensor ena akuluakulu.Ndi mphamvu zake zolimba zaukadaulo komanso mtengo wotsika mtengo, mtundu wa SRI wotsika wafalikira pakamwa ndipo umakondedwa kwambiri ndi ma laboratories apamwamba ofufuza zachipatala komanso makampani opanga ma robotic prosthetics.M'zaka zapitazi za 7, ofufuza a bionics ndi biomechanics ndi mainjiniya ochokera ku United States, China, Canada, Japan, Italy, Spain ndi mayiko ena agwiritsa ntchito masensa a SRI ultra-thin sensors kuti apange kafukufuku watsopano, adasindikiza mapepala ambiri a maphunziro ndipo apindula modabwitsa. kupita patsogolo.
M'nkhani yotsatirayi, tikuwonetsa kugwiritsa ntchito kwa SRI M35 Ultra-thin series pothandizira kukonzanso zachipatala.Kuphatikizirapo zotsatira zaposachedwa za kafukufuku wama prosthetics anzeru komanso ma exoskeleton anzeru omwe amafalitsidwa m'magazini a Nature ndi IEEE.Dzimvetserani!
