Iirobhothi ezithambileyo ezinikwe amandla ngolwelo olucinezelekileyo zinokuphonononga iindawo ezintsha kwaye zinxibelelane nezinto ezibuthathaka ngeendlela iirobhothi zemveli eziqinileyo can.But ukwakha iirobhothi ezithambileyo ngokupheleleyo kuhlala kungumngeni kuba uninzi lwamalungu afunekayo ukunika amandla ezi zixhobo aqinile ngokwendalo. Ngoku, abaphandi baseHarvard John A. Paulson School of Engineering and Applied Sciences (SEAS) baye baphuhlisa iivalve ezithambileyo zombane ukulawula i-hydraulic soft actuators.Ezi zivalo zingasetyenziselwa izixhobo ezincedisayo kunye nezonyango, iirobhothi ezithambileyo ze-bionic, i-soft grippers, iirobhothi zokuhlinzwa. , kunye nokuninzi. "Iinkqubo ezingqongqo zanamhlanje zinciphisa kakhulu ukuguquguquka kunye nokuhamba kweerobhothi ezithambileyo eziqhutywa ngulwelo," utshilo uRobert J. Wood, u-SEAS 'uHarry Lewis kunye noMarlyn McGrath ooNjingalwazi bobuNjineli kunye neSayensi eSetyenzisiweyo kunye nombhali ophezulu wephepha. iivalvu ezithambileyo, ezikhaphukhaphu zokulawula ii-actuator ezithambileyo zehydraulic, ezibonelela ngamathuba olawulo oluthambileyo ebhodini kwiirobhothi ezithambileyo ezizayo. Iivalvu ezithambileyo azintsha, kodwa ukuza kuthi ga ngoku akukho nanye ekwazile ukufikelela kuxinzelelo okanye ukuhamba okufunwayo zizivusi-manzi ezininzi ezikhoyo. Ukoyisa le mida, iqela lenze ii-electrodynamic dynamic dielectric elastomer actuators (DEAs) ezitsha. amandla aphezulu oxinaniso, alula kwaye angasebenza ngamakhulu amawaka amaxesha.Iqela lidibanise le noveli ye-dielectric elastomer actuators kunye nemijelo ethambileyo ukwenza iivalvu ezithambileyo zokulawula ulwelo. "Ezi zivalo zithambileyo zinamaxesha okuphendula ngokukhawuleza kwaye ziyakwazi ukulawula uxinzelelo kunye nokuhamba kwamanzi ukuhlangabezana neemfuno ze-hydraulic actuators," utshilo uSiyi Xu, umfundi ophumelele kwi-SEAS kunye nombhali wokuqala wephepha. kunye nee-actuator ezincinci zehydraulic ezinomthamo wangaphakathi ukusuka kumakhulu ee-microliters ukuya kumashumi eemilitha." Ukusebenzisa i-valve ethambileyo ye-DEA, abaphandi babonise ukulawulwa kwee-activators ze-hydraulic zemiqulu eyahlukeneyo kwaye bafezekise ulawulo oluzimeleyo lwee-actuator ezininzi eziqhutywa ngumthombo omnye woxinzelelo. "Le valve ye-DEA icwengileyo kunye nekhaphukhaphu yenza ukuba kulawuleke umbane ngendlela engazange ibonwe ngaphambili kwi-hydraulic actuators, ebonisa amandla okulawula iirobhothi eziqhutywa ngolwelo kwixesha elizayo," utshilo uXu. Uphononongo luhlanganiswe nguYufeng Chen, uNak-Seung uPatrick Hyun kunye noKaitlyn Becker.Yaxhaswa ngumvuzo weCMMI-1830291 kwiSiseko seSizwe seSayensi kunye neNkqubo yeSizwe yeRobhothi.
