The conducting polymers with neuron-like pattern have been polymerized and can be connected to make a network. The neuron like device or neural network device can be fabricated if three functions are added to the network of conducting polymer: I. Multilayer, II. Non-linear V-I characteristics(threshold function)), III. Weight (i.e. conductivity) control by using signals that pass in the paths of the network. In this research, the methods to add three functions have been investigated. AND and OR logical circuits have set up by a single neuron-like conducting polymer. Furthermore AND logical circuit of multilayer network has been built up by the error correcting learning method.. Synapse-type conducting polymer has been estimated as a synapse-function device using diffusion method and cross potential method. Dopant as Neurotransmitter has been injected and transmitted by diffusion and migration during a gap as synaptic cleft.
