Abstract

Official abstract text for this publication.

The present invention relates to a soft actuator moving linearly against external stimuli whose expansion and contraction can be actively controlled, suggesting that the actuator of the invention overcomes the problems of the conventional soft actuators, The soft actuator of the present invention can be repetitively driven quickly and accurately by controlling heating and cooling by using thermoelectric effect and, the soft actuator of the present invention can realize bending, tensioning, compression, and rotational driving of a tubular device containing a driver.

First claim

Opening claim text (preview).

What is claimed is: 1. A soft actuator comprising a string that is contracted or expanded by heating or cooling, the string being twisted or twisted and coiled; a thermoelectric element surrounding a surface of the string to heat or cool the string, the thermoelectric element contracting and expanding according to a contraction or an expansion of the string; and a deformable adhesive layer to connect the thermoelectric element to the surface of the string. 2. The soft actuator according to claim 1 , wherein the soft actuator additionally includes a control part to control the direction of current flowing in the thermoelectric element.
