Abstract: An actuator unit includes an actuator configured to cause a vibration by a vibrated member when a force is applied to the vibrated member and a first sensor configured to generate a first detection signal indicating a first relationship of a first physical quantity varying with time. The first physical quantity is related to the vibration of the vibrated member, a variation cycle of the first physical quantity changes based on a magnitude of the force applied to the vibrated member. The actuator unit also includes a processing circuit configured to process the first detection signal, extract a parameter indicative of the variation cycle of the first physical quantity, and estimate the magnitude of the force applied to the vibrated member based on the parameter.

Abstract: An actuator device and a method for manufacturing the actuator device, which is formed by stacking and rolling films of electrostrictive material into a cylindrical body and can ensure electrical connection with inner electrodes at both end portions of the cylindrical body. The actuator device is formed by stacking and rolling two films of electrostrictive material into a cylindrical body, the two films each having an inner electrode on one or both surfaces thereof. The cylindrical body has at least one cut portion at each end portion thereof, the cut portion being configured to reach the inner electrode (electrode pattern). By applying conductive ink to each of the cut portions, the conductive ink flows through the cut portions and reaches the inner electrodes on the films. By heat-hardening the conductive ink, it is possible to ensure electrical connection between outer and inner electrodes.
