| Outline of Final Research Achievements |
The objective of this study is to develop a measurement system for measuring and recording wave impact force acting on equipment installed on the deck of a ship. The measurement system consists of a thin and flexible wave impact force sensor by using piezoelectric polymer thin film and data logging system which is powered by photovoltaic power generation system. As the results of the research, the shape and structure of the sensor suitable for wave impact force measurement is proposed, and the water impact force measurement performance of the sensor is verified by the experiments. Furthermore, the developed measurement system uses film-type photovoltaic power generation modules to able to install on the surface of equipment. The system is possible to measure and record vibration, temperature, solar radiation, power generation, etc., and to accumulate the acquired data on a server on the cloud by wireless communication.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の目的を達成することで，これまで実船計測が困難であった甲板上の構造物，艤装品に作用する波浪衝撃力が計測可能となることで，艤装品設計技術の向上に寄与し，船舶の安全性向上に貢献できると考えられる。
また，近年，浮体式洋上風力発電に関する研究開発が実施されており，船舶とは異なり荒天時に設置位置を変更することが容易でない海上施設の安全を確保するために，将来的に本研究の成果の活用が期待できる。
