• applications. The reservoir consists of an ensemble of nonlinear ferroelectric nanodots capable of storing information through their stable polarization states. These nanodots are confined between electrodes and form a network of parallel connected capacitive elements, which can either be addressed

• nonlinear response of an ensemble of ferroelectric nanodots. The system consists of a network of nanodots, each carrying the bistable polarization state, arranged between electrodes in configurations that allow for parallel electrical addressing. By receiving temporal input signals, the ensemble evolves
