The square stack with center hole is composed of square perforated single-piece piezoelectric ceramic actuators, which are electrically connected in parallel and mechanically connected in series through external electrodes and copper foils. Compared with conventional square stacks, it has through-holes inside, which results in better thermal dissipation and facilitates the installation of various supporting components.
