    "body_text": "KAIST researchers report a monolithic nickel-titanium kirigami structure whose fold pattern and photothermal behavior are written in one ultraviolet-laser step. The laser cuts the geometry and creates a porous titanium-oxide surface that absorbs near-infrared light without a separate coating; varying the oxidation lets different regions respond in sequence. The team demonstrated reconfigurable buttons and tactile signals. The work is an institutional research report about laboratory prototypes, not a commercial display or deployed accessibility device.",
