A system and method for reducing data transfer latency and network-induced jitter in computer networks that can handle the transfer of large object data types such as multimedia objects without requiring a large local object store. A diaphragm is coated with a material capable of selectively interacting with an analyte of interest, and interaction of the analyte with the coating exerts stresses tangential to the diaphragm’s surface. The deposition of the polymer layer on the substrate may be accomplished by an ink-jet method. Then an electrolyte layer and, on the other side of the anodic support, a current collector layer are applied.
