Cellulose piezoelectric paper: Characteristics and Its Possibility for Acoustic Applications

셀룰로오스 압전종이의 특성 및 음향응용 가능성

This paper reports a piezoelectric paper made with cellulose. Since cellulose has merits in terms of biodegradability, biocompatibility, abundance in nature, lightweight and cheap, piezoelectric paper can bring a broad technological impact in many areas, for example, sensors, actuators, speakers, microphones and microelectromechanical systems. Fabrication and characterization of the piezoelectric paper are illustrated and its possibility for acoustic applications is addressed with some preliminary device demonstrations.
