Embodiment Construction

[0050] figure 1 Shown is a wearable body motion applicator consistent with a first embodiment of the present invention. The applicator comprises a flexible support 10 with a pair of electrically actuated elastic actuators 50 and a control 30 mounted on the user's body (eg, on clothing or in a pocket). The flexible support 10 includes a body 11 of stretchable fabric adapted to fit around a part of the body, such as a knee joint, and fasteners 12 for securing the support to the body. Body 11 can be made into sleeve or bandage form, as Figure 8 shown. Actuator 50 is an electrostrictive polymer actuator as is known, and consists of a non-conductive core 51 and a pair of flexible electrodes 60 located on opposite sides of core 51 . The non-conductive core 51 is made of elastic polymers such as acrylic elastomers and silicones. Such as figure 2 As shown, the actuator 50 of this embodiment is an elongated plate with two spaced apart electrodes 60 along its thickness. The elec...

Abstract

An improved human motion applicator assures a quick and sufficient amount of displacement given to a part of a human body. The applicator includes a support adapted to be fitted on the part of the human body. The support carries at least one electro-active elastic actuator in a force-transmitting relation to the human part. The actuator includes a dielectric core and a pair of electrodes on opposite of the core for receiving a driving DC voltage thereacross. The elastic actuator has a length and elastically deforms in the lengthwise direction to exert a stretching force to the human part to a greater extent as the driving DC voltage increase. The applicator also includes a controller which applies the driving DC voltage of varying levels to the elastic actuator, thereby generating a varying motion-inducing force to be applied to the part of the human body.

Description

technical field [0001] The present invention relates to a wearable body motion applicator, and more particularly to a body motion assisting or inducing device utilizing an electrically actuated elastic actuator. Background technique [0002] Human motion applicators proposed in earlier Japanese Patent Publication No. 2002-48053 use a shape memory alloy that deforms in response to heat generated by an applied electric current to give a person's A part of the body exerts a force of extension or contraction to help it perform the desired movement. However, due to the limitations of the response speed and displacement of the memory alloy, the motion applicator in the prior art is not perfect, that is, it cannot fully meet the actual needs of assisting or inducing human body motion. Contents of the invention [0003] The present invention has been improved aiming at the above-mentioned shortcoming of prior art. The present invention provides an improved human motion applicato...
