In-Materia Neuromorphic Properties Induced by Locally Denatured Regions in Sulfonated Polyaniline Networks Incorporating Au Nanoparticles (Adv. Electron. Mater. 12/2025)

Abstract

Neuromorphic Computation

Bottleneck formation in conduction paths offers a straightforward approach to generating neural-like responses. In article 2400699, Takuya Matsumoto and co-workers present a sulfonated polyaniline random network device, fabricated through simple drop-casting onto a gold nanoparticle array. This configuration promotes electric field concentration and charge accumulation, resulting in distinct nonlinear behavior and hysteresis. At room temperature, the device demonstrates a sum-of-products function with low energy consumption.
