Disembala 8 - Ofufuza ochokera ku Yunivesite ya California, Santa Barbara (UC Santa Barbara) awonetsa ukadaulo watsopano wowonetsera mu kafukufuku waposachedwa wofalitsidwa mu magazini ya Science Robotics: zithunzi zomwe zikuwonetsa sizimangowoneka komanso zimaoneka mwakuthupi. Kafukufukuyu akuyambitsa malo ocheperako a optoelectronic haptic okhala ndi ma pixel a millimeter-scale; akayatsidwa ndi kuwala kochepa komwe kumawonetsedwa, ma pixel awa amatupa ndikupanga ma bumps ogwira omwe amatha kumveka pokhudza.
Pulojekitiyi inayamba mu 2021 kuchokera ku funso losavuta lomwe linafunsidwa ndi Pulofesa Yon Visell wa ku UC Santa Barbara: Kodi kuwala komwe kumagwiritsidwa ntchito popanga zithunzi kungapangitsenso kuti makina aziyankha mwamphamvu mokwanira kuti anthu azitha kuziona? Pambuyo pa chaka chimodzi chochita ma modeling ndi kuyesa kangapo kolephera, Max Linnander, wofufuza ku yunivesiteyi, adapanga bwino chipangizo choyamba chotsimikizira lingaliro kumapeto kwa chaka cha 2022. Choyendetsedwa ndi kuwala kokha kuchokera ku laser yaying'ono ya diode ndipo chopanda zigawo zamagetsi zoyikidwa, chipangizochi chimatha kupanga ma pulse omveka bwino, omveka bwino akakhudzidwa.

Zikumveka kuti kapangidwe ka chiwonetsero chonse chomwe chafotokozedwa mu kafukufukuyu chamangidwa pa zomwe zachitikazi. Pikseli iliyonse imakhala ndi filimu yopyapyala pamwamba, mpweya waung'ono pansi pake, ndi filimu ya graphite yopachikidwa. Ikayikidwa pa kuwala, filimu ya graphite imayamwa mphamvu ya kuwala ndikuisintha mwachangu kukhala kutentha, zomwe zimapangitsa kuti mpweya womwe uli pansi pa filimuyo ukule ndikukankhira pamwamba mmwamba mpaka milimita imodzi. Kukula kwa kusamuka kumeneku ndikokwanira kuti ogwiritsa ntchito apeze ma pixels pawokha ndi zala zawo.
Popeza kuwala komweko kwa laser kumapereka mphamvu komanso ma adilesi a pixel, gulu lonselo silifuna mawaya amkati. Dongosolo losanthula mwachangu limatha kufalikira mwachangu mu gulu la ma pixel, ndikuyambitsa ma pixel amodzi ndi amodzi kuti apange zojambula zowoneka bwino komanso zogwira mtima mosalekeza.
Gulu lofufuzali lapanga bwino gulu lomwe lili ndi ma pixel opitilira 1,500 omwe angathe kulumikizidwa paokha, kupambana kwakukulu poyerekeza ndi zowonetsera zakale za haptic zomwe zidavutika kulinganiza kuchuluka kwa ma pixel, liwiro la mayankho, ndi kuchuluka kwa kusuntha. Nthawi yake yoyankhira imayambira pa ma millisecond awiri mpaka 100, yokwanira kubwereza mawonekedwe osalala, mawonekedwe, ndi mawonekedwe a anthu. Mu mayeso ogwiritsa ntchito, ophunzirawo adatha kutsatira molondola zoyambitsa zoyenda, kusiyanitsa mapangidwe a malo, ndikuwona zambiri za nthawi zomwe zimapangidwa ndi kuyatsa kwa ma pixel motsatizana.
Ofufuza akuwona kuti chifukwa cha njira yowunikira ma adilesi, ukadaulowu umapereka kuthekera kwakukulu kokulira. Ma arrays akuluakulu amatha kuyendetsedwa ndi ma laser osakanikirana omwe amagwiritsidwa ntchito kwambiri m'ma projekitala amakono. Amawonanso mitundu yosiyanasiyana ya ntchito zomwe zingatheke, monga ma interface a magalimoto a anthu ndi makina omwe amatsanzira zowongolera zakuthupi, ndi zolemba zamagetsi kapena ma diagram omwe amasinthidwa pang'onopang'ono pansi pa chikhato cha wowerenga.
Ngakhale kuti akadali mu gawo la prototype, kafukufukuyu akuyimira nthawi yoyamba kuti mphamvu ya kuwala yasinthidwa mwachindunji kukhala kusintha kwa makina ndi resolution yapamwamba. Chifukwa chake gulu la UC Santa Barbara lapanga njira yatsopano: zowonetsera zamtsogolo za haptic zidzakhala ngati zowonetsera zachikhalidwe, kupereka chidziwitso mu mtundu womwe ungawonedwe nthawi imodzi ndi maso ndikufufuzidwa ndi zala.
