Recently, many countries in the world are faced with water supply shortage and the situation is getting worse. In order to overcome this situation, a water bag was developed for sea-borne transportation and storage of water. However, it is difficult to detect its damage with conventional sensors, since a water bag is floating in the sea, flexible and more than 100 m long. Then, in this research, we propose a new damage detection technique for a large water bag by the cable theory. The equivalent circuit and a model of the water bag and its environment are considered first. When current is injected into a water bag from an electrode, obvious change of membrane potential is observed between damaged and undamaged water bags both experimentally and theologically. This will provide an easy and economical damage monitoring method for a practical usage.

近年来，世界上许多国家都面临着水资源短缺的问题，而且情况越来越严重。为了克服这种情况，人们开发了一种用于海上运输和储存水的水袋。然而，传统的传感器很难检测到它的损坏，因为水袋漂浮在海中，灵活且超过100米长。然后，在本研究中，我们提出了一种新的损伤检测技术的大型水囊的索理论。首先考虑了水囊及其环境的等效电路和模型。当电流从电极注入到水囊中时，实验和流变学上都观察到水囊损伤前后膜电位的明显变化。这将为实际应用提供一种简单、经济的损伤监测方法。
