Phetoho ea lera la likarolo tse tharo
Hangata, likonopo tse ka har'a membrane li sebelisa mebala feela ho hlalosa boemo, sebopeho le boholo ba 'mele oa bohlokoa.Ka tsela ena, ho nepahala ha ts'ebetso ho ka lemohuoa feela ke pono ea opareitara.Kaha ha ho na tlhaiso-leseling e nepahetseng ea maikutlo ho bonts'a hore na monoana o hatelloa sebakeng se sebetsang sa switch ho etsa hore switch e sebetse,
Ka lebaka leo, tšepo ea ho hlahloba mochine oohle le lebelo la ts'ebetso lia ameha.A mofuta oa lera fapoha hore etsa hore switjha senotlolo 'mele hanyenyane protrude, hanyenyane phahameng ho feta phanele ho etsa sebopeho tse tharo-dimensional, o bitsoa tse tharo-dimensional senotlolo switjha.Senotlolo sa mahlakore a mararo se ke ke sa bolela ka mokhoa o nepahetseng feela mefuta e mengata ea 'mele oa bohlokoa, ho ntlafatsa lebelo la ho lemoha, ho etsa hore ho ama ha opereishene ho be bonolo haholoanyane, empa hape ho ntlafatsa phello ea mokhabiso oa ponahalo ea sehlahisoa.Tlhahiso ea senotlolo sa mahlakore a mararo e tlameha ho etsoa mokhahlelong oa moralo oa phanele ea Tlhophiso, ka masoba a ts'ebetso bakeng sa boemo bo nepahetseng nakong ea ho hatelloa ha hlobo, 'me bolelele ba li-protrusions tsa mahlakore a mararo ka kakaretso ha boa lokela ho feta habeli botenya ba substrate.E le ho khabisa ponahalo ea sehlahisoa, li-protrusions tsa "membrane switch" e phahamisitsoeng li ka etsoa ka mefuta e mengata, 'me li tlameha ho hlophisoa ka mokhoa oa moralo oa phanele, ka masoba a matsoho e le hore ho be le boemo bo nepahetseng ha hlobo e hatelloa. , le konvex ea eona ea mahlakore a mararo Bophahamo ba lift ka kakaretso ha boa lokela ho feta botenya habeli ba karoloana.Bakeng sa ponahalo ea lihlahisoa tse ntle, li-protrusions tsa switch membrane e phahamisitsoeng li ka fetoloa ka litsela tse ngata.
