Stimulus　electro-responsive　polymer　materials　can　reversibly　change　their　physical　or　chemical　properties　under　various　external　stimuli　such　as　temperature,　light,　force,　humidity,　pH,　and　magnetic　fields.　This　review　introduces　typical　conventional　stimulus　electro-responsive　polymer　materials　and　extensively　explores　novel　directions　in　the　field,　including　multi-stimuli　electro-responsive　polymer　materials　and　humidity　electro-responsive　polymer　materials　pioneered　by　our　research　group.　Despite　significant　advancements　in　stimulus　electro-responsive　polymer　materials,　ongoing　research　focuses　on　enhancing　their　efficiency,　lifespan,　and　production　costs.　Interdisciplinary　collaboration　and　advanced　technologies　promise　to　broaden　the　application　scope　of　these　materials,　particularly　in　medical　and　environmental　protection　fields,　ultimately　benefiting　society.
