چکیده
The trend to a world with ubiquitous electronics has the need for novel concepts sensors and actuators that are lightweight, flexible, low-cost, also sustainable. Piezoelectric transducers on basis of functional polymers can meet these expectations. In this work, concept paper-embedded large-area piezoelectric devices realized solely by means roll-to-roll (R2R) mass printing post technologies including inline poling introduced. device set-up, as well process technology, offers great opportunity cost-efficient environmentally friendly production thin flexible organic devices. As layers embedded into paper hot lamination two poly(vinylidene fluoride-co-trifluoroethylene) P(VDF-TrFE) layers, printed is protected invisible. gives insights R2R 500 m long web processes electrical acoustic characterization. Fully processed show high remnant polarization up 78 mC m?2 be yield >90%. Finally, 360° surround-sound installation 387 cm consisting 56 speakers wiring presented.

Introduction to Piezoelectric Actuators and Transducers
Certain materials produce electric charges on their surfaces as a consequence of applying mechanical stress. The induced charges are proportional to the mechanical stress. This is called the direct piezoelectric effect and was discovered in quartz by Piere and Jacques Curie in 1880. Materials showing this phenomenon also conversely have a geometric strain proportional to an applied electric fie...
متن کاملHigh Temperature, High Power Piezoelectric Composite Transducers
Piezoelectric composites are a class of functional materials consisting of piezoelectric active materials and non-piezoelectric passive polymers, mechanically attached together to form different connectivities. These composites have several advantages compared to conventional piezoelectric ceramics and polymers, including improved electromechanical properties, mechanical flexibility and the abi...
متن کاملDevelopment of piezoelectric micromachined ultrasonic transducers
Piezoelectric micromachined ultrasonic transducers (pMUTs) are an example of the application of MEMS technology to ultrasound generation and detection, which is expected to offer many advantages over conventional transducers. In this work, we investigate pMUTs through novel design and fabrication methods. A finite element (FE) model, with original tools to measure device performance, was develo...
متن کاملAbsolute Ultrasonic Measurements with Piezoelectric Transducers
The absolute calibration of a piezoelectric transducer refers to the determination of the relationship between the electrical and acoustical quantities for a transducer coupled to a solid. It is shown how a well-characterized ultrasonic system, consisting of source,structure and receiver can be used to make such measurements for transducers operating as sources or receivers. Results are given, ...
