Abstract: A hydraulically amplified self-healing electrostatic (HASEL) actuator based on carbon-coated nanoparticles are disclosed. According to an embodiment of a present disclosure, the HASEL actuator includes a dielectric fluid, which is a liquid-type insulator that has polarity when voltage is applied, a film configured to covering the dielectric fluid and electrodes attached to both outer surfaces of the film and configured to move the dielectric fluid. And the dielectric fluid includes nanoparticles including ferroelectrics.

Abstract: In an apparatus and method for training artificial intelligence model for self-sensing actuator, the method includes acquiring a dataset from a shape memory alloy system by changing control parameters for controlling the shape memory alloy system, classifying the dataset into input data and ground truth data and labeling the dataset based on the ground truth data, and performing supervised training on the artificial intelligence model using the labeled dataset so that the artificial intelligence model outputs a generated force of a shape memory alloy with a specific shape or a length change of the shape memory alloy with the specific shape from the input data.
