Design equations, based on Ralph Woollett{close_quote}s 1960 report [{open_quote}{open_quote}The Flexural Disk Transducer,{close_quote}{close_quote} U.S. Navy Underwater Sound Laboratory Research Report No. 490], are presented for a bimorph accelerometer. Figures-of-merit are compared for PZT-4, PZT-5A, PZT-5H, PZT-8 piezoceramics, and PVDF-TrFE copolymer. Neutrally buoyant, spherical and cylindrical accelerometer configurations can be designed to meet bandwidth, sensitivity, and depth requirements. Experimental results for PZT-8 bimorphs indicate that simply-supported edge conditions are easily achievable. {copyright} {ital 1996 American Institute of Physics.}
