Flexible and transparent piezoelectric loudspeaker

Abstract The simple structure of flexible piezoelectric polymers implies promise innumerous applications, such as transparent loudspeakers. In this study, we fabricated and characterized a prototype loudspeaker device. The loudspeaker was fabricated using a straightforward method of sandwiching a fi...
