“…Piezoelectric and dielectric materials are ubiquitously used as sensors, actuators and transducers over a wide range of applications including but not limited to process control [1,2], industrial and automotive monitoring systems [3][4][5], medical diagnostics [6,7], aviation and aerospace structural health monitoring [8,9], embedded passive devices [10,11], and resonators and filters in telecommunications [12]. The brittle nature of homogenous ceramic piezoelectric materials limits their operational strains (~0.2% for homogenous lead zirconate titanate, PZT) [13], cycle life, and formability into complex shapes and structures [14].…”
