As a starting point, please download and read my lecture notes on ocean waves and tidal energy harvesting. My lecture notes can be downloaded from my profile in ResearchGate.net

You can construct a laboratory experiment/ test rig to mimic the cyclic mechanical energy of ocean waves and/ or tidal energy and apply this cyclic mechanical energy on a sample of the piezoelectric material. Collect the generated electric energy (collected from the cyclic mechanical stressor) using a capacitor and measure the voltage collected on the capacitor over a period of time.

Dear Prof. Yehia,

First of all. thank you for your time and answer. However, I would like to say that I tried to find the notes on your profile, but unfortunately I couldn't get it. Would you like to help me to get that?

I would love to do what you mentioned but unfortunately, I am a Physics Engineering student and in our Dept. this experiement would not be possible. I would like to know the potential of a piezoelectric sensor in order to develop a self-powered intrusion detetion device for shallow water environment. I would highly appriciate if you please guide me further in this regard.

Thank you.

Dear Abhishek,

The reference given in the link may be useful to you since it can give you information about the feasibility of using piezo electric transducers to harvest see waves.Article Piezoelectric devices for ocean energy: a brief survey
