摘要
Microtunable molds whose microtopography can be tuned post-fabrication at certain pre-defined locations were discussed. A soft lithography based on micromolding of the elastomer poly(dimethylsiloxane) (PDMS) from a microfabricated master was take as example due to their elasticity and inertness. The height of PDMS microstructures in cross-section micrographs in PDMS replicas of microtunable molds to characterize the range of membrane deflections. Microtunable molds provided an inexpensive route for fabricating microstructures that were difficult, expensive, or impossible to produce.
