Abstract:
An apparatus is provided. The apparatus includes a bidirectional comb drive actuator. The apparatus may also include a cantilever. The cantilever includes a first end connected to the bidirectional comb drive actuator and a second end connected to an inner frame. In addition, the cantilever may include first and second conductive layers for routing electrical signals. Embodiments of the disclosed apparatuses, which may include multi-dimensional actuators, allow for an increased number of electrical signals to be routed to the actuators. Moreover, the disclosed apparatuses allow for actuation multiple directions, which may provide for increased control, precision, and flexibility of movement. Accordingly, the disclosed embodiments provide significant benefits with regard to optical image stabilization and auto-focus capabilities, for example in size- and power-constrained environments.
