Firstly, we choose PDMS as the flexible material because it is widely applied in micro-fluidic chips to fabricate structures on microscale.
Silicon, the most common material in MEMS, is the ideal choice for the mold.

For this reason, there are many studies in the open literature regarding crack mechanisms in homogeneous or functionally graded materials (FGMs) involving isotropic or anisotropic material properties.
In this study, we only pay attention to the studies that have a relation with orthotropic materials.

Analysis of the AFP Process AFP is a process that combines chemical erosion and mechanical abrasion thus is suitable for machining various materials.
Material removal, based on the above analysis, is mainly from the chemical erosion and mechanical abrasion while the deposition rate of passive film protects against the material removed from the wafer.

Materials and Method Synthesis of nitrogen coated on carbon 2g of urea and 1g of PVP were dissolved in 50 mL of ultra-pure water.
For nitrogen-doped carbon, Fe-N/Gt catalyst has the smallest particle size thus increase the electrocatalytic activity of materials.
