Re: Piezoelectric dimensions problem in energy harvesting

[jagan414]

hi

I am doing project on piezoelectric energy harvesting which is a cantilever structure using COMSOL. I have some doubts related to my project. I designed cantilever structure having three layers substrate (SiC), piezo (ZnO) and electrode (Al). My doubt is that when piezoelectric layer thickness is increasing, generated electric potential values are nonlinear . But I saw theoritically electric potential is directly proportional to thickness of piezoelectric. Please anyone share the information regarding this topic.

Thank you

I wouldn't use theory for that problem. Actual devices are usually more complicated than simple theories.

Choose the actual piezoelectric device, then get the datasheet for it's properties.
