Dab-shidayaasha, oo loo yaqaan dab-shidayaasha, waxay u shaqayn doonaan sidii garaaca dheecaanka piezoelectric-ga sare ee danab sare leh oo ka imanaya koronto-dhaliye sare (fiilo dab), kaas oo burburin doona hawada u dhaxaysa elektroodhada ee dab-shidayaasha, taasoo dhalin doonta dab-shidayaal koronto si ay u shidaan isku-darka gaaska ee dhululubada. Xaaladaha aasaasiga ah ee matoorka waxqabadka sare leh: dab-shidayaal deggan oo tamar sare leh, isku-darka isku-dhafka ah, saamiga cadaadiska sare. Baabuurta leh matoorada gubashada gudaha guud ahaan waxay isticmaalaan shidaalka shidaalka iyo naaftada. Suuqa baabuurta Shiinaha, baabuurta gaaska ayaa ku jira saami weyn. Matoorada gaaska ayaa ka duwan matoorada naaftada sababtoo ah gaasku wuxuu leeyahay meel dab-shid oo sare leh (qiyaastii 400 darajo), taas oo u baahan dab-shid qasab ah si uu u shido isku-darka. Iyada oo loo marayo daadinta u dhaxaysa elektroodhada si loo soo saaro dab-shidayaal, matoorka gaaska wuxuu dhex maraa isku-darka shidaalka iyo gaaska gubasho waqtigeeda ah si uu u dhaliyo awood, laakiin sida gaas shidaal ah xitaa jawi heerkul sare leh way adag tahay in la shido si lama filaan ah, si loo sameeyo gubashadeeda waqtigeeda waa lagama maarmaan in la isticmaalo "dabka" si loo shido. Halkan dab-shidku waa shaqada "fiilo-shidaalka"
