A system for real-time monitoring of water absorption of floating materials based on underwater strain gauges, a deep-sea high-pressure simulation chamber and strain gauges has been created. Changes in the rate of water absorption of synthetic foams in a simulated high pressure environment were monitored in real time to achieve two critical hydrostatic pressures for safety and ultimate failure. The results show that a real-time water absorption monitoring using the system based on underwater deformation detection is a suitable detection method. It can truly reflect the real-time water absorption rate change of the material during a full cycle of hydrostatic pressure, which can greatly reduce the detection load and improve efficiency.
