Abstract
11 microfluidic chip device includes a substrate layer (2) and a microfluidic layer (3) . The substrate layer (2) is made from a shape memory polymer, and includes a transformative portion (21) that can change in volume when changing in shape between a memory shape and a temporary shape. The microfluidic layer (3) is laminated with the substrate layer (2) and has a microchannel (31) that is in fluid communication with the transformative portion (21) . The transformative portion (21) produces a fluid driving pressure within the microchannel (31) when changing between the memory shape and the temporary shape. A method of making the microfluidic chip device is also disclosed.
