  abstract={Process variation has always been a challenge to mitigate in electronics. This especially holds true for organic semiconductors, where reproducibility concerns hinder industrialization. Challenging this concept, we show AC-electropolymerization to be a powerful platform for the development of morphology-dependent computing hardware, thanks precisely to its intrinsic stochasticity. Our findings reveal that electropolymerized polymer dendrite networks exhibit a complex structure-operation relationship that allows to implement nearly linear to nonlinear functions. Moreover, dendritic networks can integrate a limitless number of inputs from their environment, which can be used to our advantage in the context of in materio computing to discriminate between different spatiotemporal inputs. These results position electropolymerization as a pivotal technique for the bottom-up implementation of computationally powerful objects. We anticipate this study to help shifting the negative perception of variability in the material science community and promote the electropolymerization framework as a foundation for the development of a new generation of hardware defined by its topological richness.
