Abstract
The present invention provides electroactive polymer transducers configured for surface mode deformation to provide thickness mode actuation. The inventive transducers may find use in various applications, including but not limited to haptic feedback for user interface devices (e.g., key buttons, key pads, touch pads, touch screens, touch plates, touch sensors, etc.), fluid movement and control mechanism such as pumps and valves, breaking and clutch mechanisms, power generation, sensing, etc.
