An actuator includes an actuator body that includes a first surface and a second surface that face each other, a first constraining member that is provided on the first surface, and constrains the first surface from expanding and contracting, and a second constraining member that is provided on the second surface, and constrains the second surface from expanding and contracting. The actuator body includes a first electrode, a second electrode that faces the first electrode, and an elastomer layer that is provided between the first electrode and the second electrode. The first electrode is a pattern electrode. The first constraining member and the second constraining member are provided correspondingly to the first electrode.

Actuator, drive apparatus, and electronic apparatus

An actuator is provided with a tubular actuator element and a supporting body which supports an inner peripheral surface of the actuator element. An internal pressure of the actuator element is higher than an external pressure of the actuator element.

Actuator, actuator module, endoscope, endoscope module, and controlling method

An actuator includes a stack including: an elastomer layer; and an elastic electrode disposed on each surface of the elastomer layer, in which the stack is subjected to a pre-strain of 50% or more at least in one direction. The stack may have a round tubular shape with the elastic electrodes disposed on opposite surfaces of the elastomer layer in a radial direction of the stack.

Actuator including elastomer layer and elastic electrodes and method for manufacturing the same

An actuator includes a laminate including an elastomer layer and an electrode, in which the laminate has a spiral or concentric shape, pre-distortion is applied to at least one member out of the elastomer layer and the electrode, and area distortion of the at least one member is 10% or larger.

Actuator, driving member, tactile sense presenting device, and driving device

A shake correction device including a driven body, a first actuator that is extendable and contractible in a first direction, a second actuator that is extendable and contractible in a second direction, a support that supports the driven body via the first actuator and the second actuator, a first connection mechanism unit that connects at least either between the first actuator and the driven body or between the first actuator and the support, and a second connection mechanism unit that connects at least either between the second actuator and the driven body or between the second actuator and the support. The first connection mechanism unit and the second connection mechanism unit have at least one degree of rotational freedom.

Shake correction device including dielectric elastomer actuator, driving device, imaging device, and electronic device

[Solving Means] A force-sense presenting apparatus includes a casing structure, a weight, and a drive unit. The weight is provided in the casing structure or incorporated in the casing structure. The drive unit includes a first supporting portion constituted of a pair of supporting structures that support a first side of the weight and a second side opposed to the first side, at least one of the pair of supporting structures being configured to include an actuator capable of providing the weight with biased acceleration.
