摘要

We introduce a reconfigurable electronic system, termed laser-induced PEDOT:PSS/A-cLCE (LIPAL), integrating a transparent electrode with a photoresponsive substrate. The azobenzene-functionalized semi-crystalline LCE undergoes light-induced shape change, while 532 nm laser-patterned PEDOT:PSS forms conductive pathways. The grid-patterned electrode (0.1–0.4 mm periodicity) permits light penetration, enabling bidirectional bending and stable conductivity under deformation. Additionally, dehydration-induced contraction of PEDOT:PSS under visible light provides complementary actuation, expanding the deformation modes of LIPAL for advanced reconfigurable electronic systems.
