Underwater acoustic measurement has received great attention in the twenty-first century, and the use of polyvinylidene fluoride (PVDF) film for hydrophone application has been widely explored. However, its sensing mechanism remains unclear. In this thesis, analytical and numerical models are developed to understand the responses of PVDF films to plane sound waves. The coupling between underwater sound field, PVDF film and coatings are investigated in detail. With this new understanding, a significant advance in enhanced design ability of PVDF film-based hydrophones is made. Two types of sound intensity probes are designed. They show great potential for practical applications.
