This work aims to provide early-stage insights into an electrothermally actuated liquid crystal elastomer (LCE) fber for novel shape-changing behaviors that are both programmable and reversible. We build a control system and experimentally investigate the electro-thermal characteristics and actuation, identifying four categories of fber behavior: Oscillating Tip, Oscillating Fiber, Tilting and Bending. These key parameters illustrate the broad application potential of the proposed approach
