Fabrication and Training of 3D Conductive Polymer Networks for Neuromorphic Wetware

The human brain possesses an exceptional information processing capability owing to the 3D and dense network architecture of numerous neurons synapses. Brain-inspired neuromorphic hardware can also benefit from architectures, such as high integration circuits acquisition highly complex dynamical systems. In this study, for future engineering, conductive polymer networks consisting poly(3,4-ethylenedioxy-thiophene) doped with poly(styrene sulfonate) anions (PEDOT:PSS) are successfully stably fabricated between multiple electrodes scratch in precursor solution by electropolymerization. efficiently emulate local connections neighboring observed cortex. This novel technology, which allows wiring only desired electrodes, is unprecedented has potential underlying technology integration. Furthermore, experimental results conclusively prove that conductance modification be performed manipulating physical chemical properties branch-wired wires, thus demonstrating first time feasibility wetware enhanced biological plausibility subsequent post-Moore era.
