bimorph bender transducer

Dear experts,

to develop a present application I would need design a bimorph bender tranduscer in parallel configuration. I believe that the response of such a transducer depends only on the dimensions (thickness, free length, clamped length, and width) of the bimorph as well as the piezoceramic material that compounds.

My question is how, or in other words what is the relation between the response of the bimorph (bending in cantilever configuration) (resonance frequency, bandwidth, displacement, voltage needed...) and its dimensions (T, FL, CL, W) and nature. How should be designed, starting from the response specifications, the dimensions and nature of the bender???

I would grateful any clues or references of books or web pages, journal articles... where it could be explained.

Thanks in advance.

The properties of bender widely vary depending on the design (monomorph, bimorph, trimorph), driving
conditions and PZT material. Basic relations for example are given in the company paper
"Piecoelectric Ceramics", Philips Components, Eindhoven, The Netherlands (1991). A paper covering
the topic with 95 citations: Jan G. Smits et al., Sensors and Actuators A, 28 (1991) pp. 41 - 61.
