The present invention discloses a liquid leakage warning device suitable for being placed on a wound dressing, and the liquid leakage warning device comprises a liquid permeation sensing chip and a warning module. The osmotic induction wafer is attached to the wound dressing, and the osmotic induction chip is electrically conductive to generate an inductive signal corresponding to the penetration of the osmotic liquid. The warning module is connected to the liquid permeation sensing chip and receives the sensing signal, and generates a warning signal corresponding to the sensing signal.本創作係揭露一種滲液警示裝置，適用於置放在傷口包紮處之上，滲液警示裝置包含滲液感應晶片及警示模組。滲液感應晶片貼覆於傷口包紮處上，滲液感應晶片對應滲液滲透而導電產生感應訊號。警示模組連結滲液感應晶片且接收感應訊號，並對應感應訊號產生警示訊號。
