Flammability is a significant challenge in polymer-based strain sensing applications. In addition, the existing intrinsic flame retardant not elastic at room temperature, which may potentially damage flexible equipment. This study presents series of flame-retardant ionic conductive elastomers (ICEs) (denoted as PCAIPx) containing phosphorus from phytic acid (PA) and nitrogen choline chloride (ChCl) with multiple hydrogen bonds synthesized using simple efficient one-pot UV-initiated radical copolymerization polymerizable deep eutectic solvent (PDES). The limiting oxygen index (LOI) value increased 24.1% for pure PCAI without PA to 38.3% PCAIP7.5. SEM analysis residual char shows that formation dense continuous layer effectively worked shield, preventing further decomposition undecomposed polymer inside while hindering transmission heat mass isolating required combustion. bonds’ cross-linked structure phosphorus-containing elastomer demonstrate superior elasticity (elongation break up 2109%), durability, tear resistance excellent adhesive properties. Application PCAIPX sensors showed has cyclic stability exhibited repeatable stable change signals response repetitive bending motions wrist, fingers, elbow, knee. Consequently, this provides strategy development ICE can reduce fire hazards be applied other fire-risk fields such personal protection, firefighting, sports
