Abstract: Piezoelectric thin films offer a number of advantages in various applications, such as high energy density harvesters, a wide dynamic range, and high sensitivity sensors, as well as large displacement and low power consumption actuators. This review covers the available material forms and applications of piezoelectric thin films: lead zirconate titanate (PZT)-based thin films, lead-free piezoelectric thin films, piezopolymer films, cellulose-based electroactive paper (EAPap), and many other thin films used for electromechanical transduction. The electromechanical properties and performances of piezoelectric films are compared and their suitability for particular applications are reported. The key ideas of piezoelectric thin films are reviewed and discussed for sensory and actuation systems, energy harvesting, and medical and acoustic transducers. In the last section, an insight into the future outlook and possibilities for thin film-based devices and their integration into real-world applications is presented.

TL;DR: In this paper, the possibility of cellulose-based electro-active paper (EAPap) as a vibrational energy transducer was investigated, and the voltage output of the EAPap was measured under harmonic base excitation of the cantilever beam.

TL;DR: It can be concluded that the piezoelectricity of cellulose-based EAPap can be used in energy transduction application.

TL;DR: In this article, a vibration sensor made of piezoelectric paper was used to measure the frequency response function of an aluminum cantilever that was subjected to impulse loading and random excitation, and the results revealed that the dynamic sensing ability of the EAPap at a low frequency range was quite comparable to that of PVDF when monitoring structural vibrations.
