STRETCHABLE FIBER, STRETCHABLE SHEET EMPLOYING STRETCHABLE FIBER, AND ASSIST DEVICE EMPLOYING STRETCHABLE SHEET

摘要

PROBLEM TO BE SOLVED: To provide a stretchable fiber capable of giving a sense of fitting to a person and supporting various actions of the person, a stretchable sheet formed from the fiber, and clothing employing the stretchable sheet.SOLUTION: A stretchable fiber 1 includes: a first conductive fiber 11 including an electric field responsive gel-state polymer layer 13; and a second conductive fiber 14 that imparts an electric field to the first conductive fiber 11. The first conductive fiber 11 is wound around the second conductive fiber 14 while entirely or partially bringing the first conductive fiber 11 and the second conductive fiber 14 into contact in a length direction of the first conductive fiber 11 and the second conductive fiber 14. The stretchable sheet formed from the stretchable fiber and an assist device employing the stretchable sheet are also disclosed.SELECTED DRAWING: Figure 1
