Inkjet printing is considered to be a key technology in the field of flexible electronics due to its capability to deposit different types of materials in a controlled and defined manner. However, inkjet printing of functional materials such as the fluorinated piezoelectric copolymer P(VDF–TrFE) still remains a challenge. In this regard, a piezoelectric ink was formulated in a narrow viscosity range compatible with the specific print head used in this work. Characterization of the dielectric, ferroelectric and piezoelectric properties along with the morphology and crystallinity of the film showed excellent agreement with traditional solution processed thin films. Consequently, inkjet printed P(VDF–TrFE) layers were subsequently integrated as a functional layer into entirely inkjet printed flexible electronics devices such as energy harvesters, sensors and actuators contributing to the development of flexible electronic applications.

所有喷墨打印的压电电子设备：能量产生器，传感器和执行器

喷墨打印被认为是柔性电子领域的关键技术，因为它具有以受控和定义的方式沉积不同类型的材料的能力。但是，功能材料（如氟化压电共聚物P（VDF-TrFE））的喷墨打印仍然是一个挑战。在这方面，压电油墨被配制在与该工作中使用的特定打印头兼容的窄粘度范围内。介电，铁电和压电特性以及薄膜的形态和结晶度的表征与传统的固溶处理薄膜表现出极好的一致性。因此，随后将喷墨印刷的P（VDF-TrFE）层作为功能层集成到了完全喷墨印刷的柔性电子设备中，例如能量收集器，
