2034500 9013367 PCTABS00002 A large area transducer suitable for use in a hydrophone comprises a sheet (6) of polyvinylidene fluoride/trifluoro ethylene formed with a plurality of dome-shaped protrusions (7) which may be formed simultaneously using a vacuum forming an injection moulding technique. The dome-shaped protrusions (7) are closed by a rigid baseplate (8) to enable the transducer to operate in the transverse mode.
