Memristive Circuit Design of Evolution and Decay of Emotion and Its Implementation in PAD Emotional Space

Current memristive circuits only focus on the generation of emotion, without considering the evolution and decay process of emotion. In this paper, a memristive circuit that can more efficiently realize the generation of emotion is designed, which also takes into account the evolution and decay of emotion. The designed circuit mainly consists of signal processing module, logic selection module, emotion generation module, personality module and emotion expression module. The composite signals are generated through different tactile, olfactory and gustatory stimuli. The combination of different tactile, olfactory and gustatory stimuli can produce six different control signals through the logic selection module. The emotion generation module achieves the generation and evolution of emotions, while also considering the process of emotion decay under different personality traits. Finally, a three-dimensional pleasure arousal dominance (PAD) emotional space is proposed, which can express continuous emotions according to pleasure signals, arousal signals and dominance signals. The feasibility of the circuit is verified by PSPICE. The proposed circuit may provide some references for the development of artificial emotion.
