Abstract
A method of transducing electrical energy to sound is disclosed which includes providing a transducer, the transducer includes lead zirconate titanate (PZT) particles mixed with graphene nanoplatelets (GNPs) in a flexible substrate aligned in a first direction, forming a transducer subsystem, a first conductive protective electrode having a width and a length configured to provide a first electrical connectivity to an external circuit, and a second conductive protective electrode having the width and the length and configured to provide a second electrical connectivity to the external circuit, wherein the transducer subsystem is sandwiched between the first and second conductive protective electrodes, and providing an external circuit configured to provide an electrical signal to the first and second conductive protective electrodes to thereby transduce the electrical signal to sound.
