Abstract:
1. An actuator device, the actuator device comprising: a substrate member, the substrate member comprising a surface region; a movable compliant actuator member having a fixed end, a free end, and a length formed between the fixed end and the free end, the fixed end being coupled to a portion of the surface region, the actuator member having at least a first state at a first spatial position and a second state at a second spatial position, the free end being at the first spatial position during the first state, the first spatial position being a first predetermined height normal to the surface region and the second spatial position being a second predetermined height normal to the surface region; an arc region defining a path between the first spatial position and the second spatial position, the actuator member being in a stressed state at the second spatial position, the stressed state being in a direction toward the first spatial position; a plurality of electrode members spatially disposed along a first region of the surface region and a second region of the surface region, the first region being within a vicinity of the portion of the surface region coupled to the fixed end of the movable compliant actuator member;
