Microelectrochemical logic circuits.

We report microelectrochemical devices that mimic some functions of solid-state circuit components such as diodes and transistors. The operation of this new family of devices is enabled by a network of microfluidic electrochemical cells that communicate with one-another via conductive solutions and, in some cases, bipolar electrodes. The output of the devices can be either electrochemical or optical. The approach reported here is a first step toward the development of large-scale integrated electrochemical systems having parallel processing capabilities.
