Abstract: A multi-axis inertial force sensor includes a mounting material, blocks, and sensors. Each block has a positioning portion that determines its position relative to a contact partner. A pedestal is formed by an assembly of the blocks where the positions are determined relative to each other based on the positioning portion and where inclined surfaces are oriented in different directions. The sensors are respectively arranged on the inclined surfaces of the pedestal so that the main axes are oriented in different directions to detect vector components of inertial force corresponding to the main axes.

Abstract: An electrostatic actuator includes a fixed electrode and a movable electrode arranged to face the fixed electrode. The movable electrode is configured to be displaceable with respect to the fixed electrode and a fixed portion. An attractive force acts between the movable electrode and the fixed portion. In the electrostatic actuator, a non-linear vibration of the movable electrode when a voltage is applied to the fixed electrode and the movable electrode is reduced by the attractive force acting between the movable electrode and the fixed portion.
