NOVELTY - A transducer comprises lead zirconate titanate particles mixed with graphene nanoplatelets in a flexible substrate aligned in a direction (D1) to form a transducer subsystem, a conductive protective electrode (E1) having a width and a length providing an electrical connectivity to an external circuit, and conductive protective electrode (E2) having the width and the length providing an electrical connectivity to the external circuit. The transducer subsystem is sandwiched between the conductive protective electrodes (E1) and (E2). USE - Transducer e.g. loudspeaker (claimed). Uses include but are not limited to wearable speakers, active noise cancellation systems in automobiles, transparent loudspeaker windows, self-read e-books, e-newspapers, television screens, computer monitors, ultra-sensitive force sensors, microphones, nanogenerators, etc.
