“…3D model of PMUT element with first layer and third layer (top and bottom electrode) were composed by copper, second layer with blue region is the active material layer and fourth layer is the silicon dioxide as supporting layer.This structure was simulated in a water medium setting with six different active materials which were PZT-5A, PZT-5H, aluminium nitride, lithium niobate, quartz, and zinc oxide. The designed structure was modelled referring parameters to the existing PMUT basic structure Akasheh, Myers, Fraser, Bose & Bandyopadhyay, 2004;Ahmad, A. Manaf, Yaacob & A. Rahman, 2017) by using finite…”
