Some new applications of physical chemistry to MEMS

If the product generated at an electrode can be rapidly consumed through a homogeneous scavenging reaction, the product will be confined within a very thin diffusion layer surrounding the electrode surface, called "Electrochemical Reaction Layer". The surface tension between an aqueous solution and hydrophilic/hydrophobic solid surface provides a simpler way to control fluid movement in micro-systems. According to this principle, a novel integrated print head was developed by our research group. In order to mobilize or stop the fluids or biological entities in the BioMEMs system and μ-TAS, micro fluid actuator (micro pump) is needed as one of the key components.
