摘要： An artificial muscle structure has an electro-active polymer (EAP) layer having a frusto-conical shape and whose tip has an opening formed therein for use as a camera variable aperture. First, second and third electrode segments are formed on a rear face of the EAP layer. The second segment is positioned in a gap between the first and third segments so as to be electrically isolated from the first and third segments. The second segment has an opening formed therein that is aligned with the opening in the EAP layer. A complementary electrode is formed on a front face of the EAP layer. Other embodiments are also described.

摘要： A hybrid sensor shift platform for an optical image stabilization (OIS) actuator mechanism in compact camera modules includes two or more substrates. A top substrate is composed of an organic material (e.g., a resin) to reduce mass, reduce magnetic interaction with permanent magnets, and improve reliability. One or more lower substrates of the hybrid sensor shift platform are ceramic substrates that provide the benefits of ceramics for connection to the image sensor. The organic substrate is connected via a solder bond process to the lower ceramic substrate(s). The connection between the substrates is reinforced with an under-fill of epoxy that surrounds the solder bonds, thus creating a full interface between the substrates within the overlap.
