Piezoelectric transducer (10) is made from a piezoelectric polymer film (14') which has ground electrode (48) with lead (52) deposited on one surface and a signal generating electrode (42) with lead (46) on the other, the leads being parallel but in staggered relationship. Electrical connections are made to the leads by electrically disposing them on the same film surface. This is achieved by forming a channel (60) through the film which pierces one of the leads (46) to form a pierced lead and applying conductive material (62) over the channel to provide a linking lead on opposite surfaces, the conductive material coating the sidewalls of the channel to effect continuity between pierced lead and linking lead. The conductive material is resilient, durable, and rubber-like. It has a polymer matrix in which conductive metal, silver, nickel, or copper, is embedded. The electrodes and leads are made of the same conducting material.
