Izingxenye ezithambile zamarobhothi athambile esizukulwane esilandelayo ScienceDaily

Amarobhothi athambile anikwa amandla uketshezi olucindezelwe angahlola izindawo ezintsha futhi ahlanganyele nezinto ezithambile ngezindlela amarobhothi aqinile angakwazi.Kodwa ukwakha amarobhothi athambile ngokugcwele kuseyinselele ngoba izinto eziningi ezidingekayo ukunika amandla lezi zixhobo ziqinile ngokwemvelo. Manje, abacwaningi base-Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) benze ama-valve athambile kagesi ukuze alawule ama-hydraulic soft actuators.Lawa mavalvu angasetshenziswa emishinini yokusiza neyokwelapha, amarobhothi athambile e-bionic, ama-soft gripper, amarobhothi okuhlinzwa. , futhi nokuningi. "Izinhlelo zanamuhla zokulawula eziqinile zinciphisa kakhulu ukuguquguquka nokuhamba kwamarobhothi athambile aqhutshwa uketshezi," kusho uRobert J. Wood, u-SEAS' uHarry Lewis kanye noMarlyn McGrath Osolwazi Bobunjiniyela Nesayensi Esetshenziswayo kanye nombhali omkhulu wephepha." Lapha, senze ama-valve athambile, angasindi okulawula ama-actuator athambile e-hydraulic, anikeza ithuba lokulawula okuthambile okusebhodini kwamarobhothi athambile athambile akusasa." Amavalvu athambile awawona amasha, kodwa kuze kube manje awekho akwazile ukuzuza ingcindezi noma ukugeleza okudingwa ama-hydraulic actuators amaningi akhona. Ukuze linqobe le mikhawulo, iqembu lenze ama-electrodynamic dielectric elastomer actuators (DEAs) amasha. amandla aphezulu, anesisindo esincane futhi angasebenza izikhathi ezingamakhulu ezinkulungwane.Ithimba lahlanganisa lezi zici ze-dielectric elastomer actuators namashaneli athambile ukuze kwakheke ama-valve athambile okulawula uketshezi. "Lawa ma-valve athambile anezikhathi zokuphendula ngokushesha futhi angakwazi ukulawula umfutho woketshezi nokugeleza ukuze ahlangabezane nezidingo zama-hydraulic actuators," kusho uSiyi Xu, umfundi oneziqu e-SEAS nombhali wokuqala wephepha. kanye nama-actuator amancane anamanzi angaphakathi asukela kumakhulu ama-microliter kuya emashumini amamililitha." Besebenzisa i-valve ethambile ye-DEA, abacwaningi babonise ukulawulwa kwama-hydraulic actuators amavolumu ahlukene futhi bathola ukulawulwa okuzimele kwama-actuator amaningi aqhutshwa umthombo owodwa wengcindezi. "Le valve ye-DEA ehlangene futhi engasindi inika amandla ukulawulwa kukagesi okungakaze kubonwe kuma-hydraulic actuators, okukhombisa amandla okulawula ukunyakaza kwamarobhothi aqhutshwa uketshezi oluthambile esikhathini esizayo," kusho uXu. Ucwaningo lubhalwe ngokubambisana ngu-Yufeng Chen, uNak-Seung Patrick Hyun kanye no-Kaitlyn Becker.
