Abstract

There is provided an electro-mechanical device comprising a first array comprising a plurality of first actuator elements, and a second array comprising a plurality of second actuator elements, the first array and the second array being located on a same substrate, wherein each of the first actuator elements is not electrically connected to any one of the second actuator elements, wherein control of an application of a voltage to at least one of a moving element or an electrode of an actuator element enables controlling motion of the moving element, wherein the first actuator elements are arranged along NR1 rows and NC1 columns, wherein NR1≥1 and NC1≥1, wherein at least one of NR1 or NC1 is equal to or larger than 2, wherein the second actuators elements are arranged along NR2 rows and NC2 columns, wherein at least one of NR2 or NC2 is equal to or larger than 2.
