Abstract:
1. A method of microfabricating an elastomeric structure, comprising: forming a first elastomeric layer on a substrate; curing the first elastomeric layer; patterning a first sacrificial layer over the first elastomeric layer; forming a second elastomeric layer over the first elastomeric layer, thereby encapsulating the first patterned sacrificial layer between the first and second elastomeric layers; curing the second elastomeric layer; and removing the first patterned sacrificial layer selective to the first elastomeric layer and the second elastomeric layer, thereby forming at least one first recess between the first and second layers of elastomer; wherein at least one of the first or second elastomeric layers comprises a magnetic portion.
