Embodiment

[0087] An experiment of generating a load (generating force) was carried out using an example of an actuator device provided with a protrusion on a base member and a comparative example of an actuator device not provided with a protrusion. It should be noted that the polymer actuator used in the experiment is formed with figure 1 Both the unilaterally supported type and the butterfly configuration are shown.

[0088] First, when using figure 1 In the case of the one-side support type shown, the total length of the actuator 10 is 5 mm, and in the embodiment, the protrusion 60 is formed at a position 3 mm away from the fixed end 14 toward the free end 16 .

[0089] In addition, using Figure 10 In the case of the shown butterfly structure, the total length of the actuator 10 is 10 mm, and in the embodiment, the protrusion 66 is formed at a position 4 mm from the central support 53 toward both sides.

[0090] In the experiment, the applied voltage between the electrode layer...

Abstract

Disclosed, in particular, is an actuator device and input device that can achieve great reaction force, without sacrificing the amount of displacement. The actuator device is provided with an actuator (10) that has one of its ends made to be an anchoring end (14) and the other end made to be a free end (16), and which is bendable when a voltage is applied; and a base member (17) that has an anchoring section (15) that anchors the anchoring end (14) of the aforementioned actuator (10). A protrusion section (60) is provided on the base member (17). When the aforementioned actuator (10) is put in a bent state and a force in the opposite direction of the bending is applied to and deforms the aforementioned free end (16), the actuator (10) will come in contact with the protrusion section (60). The protrusion section (60) will become the fulcrum of deformations, and the reaction force can be made to be greater by the principle of the strength of materials, without sacrificing the amount of displacement.

Description

technical field [0001] The present invention relates to an actuator (actuator) device and an input device including an actuator with one end being a fixed end and the other end being a free end that can bend when a voltage is applied. Background technique [0002] Figure 14 (a) and (b) are schematic diagrams (sectional views) of an input device for explaining conventional problems. [0003] Figure 14 The input device 1 shown in (a) is configured to include an actuator 2, a base member 3, a support portion 4, a key top 5, a housing 6, and the like. [0004] Such as Figure 14 As shown in (a), each actuator 2 is supported on one side by the support portion 4 . The actuator 2 is configured to include an electrolyte layer and a pair of electrode layers provided on both sides in the thickness direction of the electrolyte layer. Furthermore, when a voltage is applied between the pair of electrode layers on the fixed end side, as Figure 14 It bends upward as shown in (a) (see ...
