Subject: Can a vibrating unit be made from piezo ceramics?

I am a university student, and have project where I
have to design and build an object to produce similar
vibration to that of an insect. It also has to be
small, approximately 1cm x 1cm x 2cm. I was planning
to use piezo ceramics and a watch battery. Is this
possible? If so how would I do it (i.e. material
required, possible circuits)? Or is there another type
of circuit I could try besides a piezo ceramic one?
Any help you could provide would be greatly
appreciated.

Thank you
Luke
