Surface shape variable sheet and surface shape variable device

摘要

PROBLEM TO BE SOLVED: To provide a technique capable of switching a deformation pattern of a sheet surface from a plurality of types. SOLUTION: A variable surface shape sheet is provided on a sheet body made of an elastic material having a dielectric property, a one-side electrode provided on one side of the sheet body, and another side on the back side of the one side. The first electrode is provided with an other side electrode to which a voltage is applied to and from the one side electrode, and the one side electrode faces a part of the other side electrode via the sheet body. And a second electrode that faces another part of the other side electrode via the sheet body and is electrically independent of the first electrode on the one side. [Selection diagram] Fig. 4
