Classification: CPC H | IPC C  H

Claim 0:
1. A method of transducing electrical energy to sound, comprising:
providing a transducer, the transducer comprising:
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 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.
