Abstract
A laminate including a base member, and a hydrogel layer whose forming material is a hydrogel, the hydrogel layer being provided on a surface of the base member. An adhesive region and a non-adhesive region are formed at an interface between the base member and the hydrogel layer, the adhesive region being a region where the base member and the hydrogel layer adhere to each other, the non-adhesive region being a region where the base member and the hydrogel layer do not adhere to each other.
Claims19
A laminate comprising:
- a base member having a first surface including a first adhesive region, a second adhesive region, and a non-adhesive region disposed between the first adhesive region and the second adhesive region;
- and
- a hydrogel layer including a stimuli-responsive hydrogel that is configured to reversibly deform in response to a stimulus, at least a portion of the hydrogel layer contacting the first surface of the base member,
- wherein the hydrogel layer is configured to adhere to the base member at the first and second adhesive regions,
- wherein the hydrogel layer is configured to be spaced apart from the base member at the non-adhesive region, and
- wherein the stimulus is selected from the group consisting of:
- heat, light, a magnetic field, an electrical current, pH, or combinations thereof.

A shape control device comprising:
- a base member including glass, a surface of the base member including a first adhesive region, a second adhesive region, and a non-adhesive region disposed between the first adhesive region and the second adhesive region, the non-adhesive region defining a band shape extending in a first direction parallel to the surface, and each of the first and second adhesive regions extending in the first direction;
- and
- a hydrogel layer including a hydrogel, the hydrogel layer disposed on the surface of the base member,
- wherein in a first position, the hydrogel layer contacts the surface of the base member at the first adhesive region, the second adhesive region, and the non-adhesive region, and
- wherein in a second position, the hydrogel layer contacts the surface of the base member at the first adhesive region and the second adhesive region and is spaced apart from the base member at the non-adhesive region, and
- wherein in the second position, a channel extends between the hydrogel layer, the surface of the base member, the first adhesive region, and the second adhesive region.
3 more elements
A shape control device comprising:
- a base member including glass, the base member including a first adhesive region, a second adhesive region, and a non-adhesive region disposed between the first adhesive region and the second adhesive region;
- a hydrogel layer including polyisopropylacrylamide, the hydrogel layer disposed on a surface of the base member;
- and
- an input unit,
- wherein the hydrogel layer is configured to adhere to the base member at the first and second adhesive regions and to be spaced apart from the base member at the non-adhesive region,
- wherein the hydrogel layer is configured to reversibly deform in response to a stimulus in a direction perpendicular to the surface of the base member at the non-adhesive region,
- wherein the input unit is configured to input the stimulus to the hydrogel layer, and
- wherein the stimulus is heat.
