초록
We fabricated and tested porous silicon-based electroosmotic pumps. Compared to other pumping media, porous silicon is beneficial for obtaining comparable flow rates with much lowered electric potential, while maintaining enough mechanical properties. We fabricated porous silicon with two sided-reactive etching processes. We found higher flow rate per electric potential (consistent with previous studies) and we also found asymmetric flow rates for different pumping directions. We plan to utilize this asymmetry for AC pumping applications.
