What Is the Dynamic Capacitance of a Memristor?
Juan Bisquert, Gonzalo Rivera-Sierra
Impedance spectroscopy of memristors, nanofluidic channels and halide perovskite devices often shows a low-frequency capacitance that is orders of magnitude larger than any plausib…
Noise-Resilient Detection of Neuronal Spikes by a Hopf-Bifurcation Device
Jitendra Kumar, Roberto Fenollosa, Gonzalo Rivera-Sierra +4
Detecting weak transient signals in noise is a persistent challenge in sensing, communication, and electrophysiology. Here, we demonstrate a physical weak-signal detector based on…
Organic Electrochemical Neurons: Nonlinear Tools for Complex Dynamics
Gonzalo Rivera-Sierra, Roberto Fenollosa, Juan Bisquert
Hybrid oscillator architectures that combine feedback oscillators with self-sustained negative resistance oscillators have emerged as a promising platform for artificial neuron des…
Relaxation Time of Multipore Nanofluidic Memristors for Neuromorphic Applications
Agustin Bou, Patricio Ramirez, Juan Bisquert
Memristors have been positioned at the forefront of the purposes for carrying out neuromorphic computation. Their tuneable conductivity properties enable the imitation of synaptic…
