Claim 0:
1. A system, comprising:
a flexible 1-3 piezo-composite transducer comprising:
a plurality of 1-3 composite pillars extending upwardly from a transducer substrate, individual ones of the plurality of 1-3 composite pillars formed of an active piezo-electric material, the active piezo-electric material comprising lead zirconate titanate (PZT-5H) ceramic; and
a passive polymer matrix formed of a flexible material positioned between the plurality of 1-3 composite pillars, the flexible material comprising polydimethylsiloxane (PDMS);
a first electrode positioned on each side of the flexible 1-3 piezo-composite transducer; and
a second electrode positioned on each side of the flexible 1-3 piezo-composite transducer;
wherein the second electrode is a single layer composite formed of silver nanowires and PDMS.
