Abstract
A method for forming a stretchable platform according to one embodiment comprises: (a) a step of forming an adhesive layer on one surface of a rigid member; (b) a step of modifying one surface of a stretchable substrate and an adhesive layer surface to form an incomplete bond; and (c) a step of bonding so as to form a covalent bond between the one surface of a modified stretchable substrate and the adhesive layer surface.
Claims10
A stretchable platform formation method, comprising the steps of:
- (a) forming an adhesive layer on one surface of a rigid member;
- (b) modifying one surface of a buffer pattern and one surface of the adhesive layer such that an incomplete bond is formed;
- (c) bonding the modified surface of the buffer pattern and the modified surface of the adhesive layer;
- (d) modifying the other surface of the buffer pattern and one surface of a stretchable substrate such that an incomplete bond is formed;
- and
- (e) bonding the other surface of the buffer pattern and the one surface of the stretchable substrate,
- wherein the rigid member has a higher Young's modulus than the buffer pattern and the buffer pattern has a higher Young's modulus than the stretchable substrate, and
- wherein both the buffer pattern and the stretchable substrate are formed of polydimethylsiloxane (PDMS).

A stretchable platform comprising:
- a stretchable substrate;
- a rigid member located on the stretchable substrate;
- a buffer pattern located between the rigid member and the stretchable substrate;
- and
- an adhesive layer located between the rigid member and the buffer pattern and configured to bond the rigid member and the buffer pattern,
- wherein the adhesive layer forms a covalent bond with the buffer pattern to bond the rigid member and the buffer pattern,
- wherein the rigid member has a higher Young's modulus than the buffer pattern and the buffer pattern has a higher Young's modulus than the stretchable substrate, and
- wherein both the buffer pattern and the stretchable substrate are formed of polydimethylsiloxane (PDMS).
