High 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 کاملPiezoelectric materials for high temperature transducers and actuators
Piezoelectric sensors and actuators are a mature technology, commonplace amongst a plethora of industrial fields including automotive, maritime and non-destructive testing. However the environments that these devices are required to serve in are becoming more demanding, with temperatures being driven higher to increase efficiencies and reduce shut-downs. Materials to survive these temperatures ...
متن کاملHigh Efficiency Non-contact Transducers and a Very High Coupling Piezoelectric Composite
Despite the usefulness of ultrasound for materials analysis, this age-old method has been stifled by direct or indirect transducer contact to the test media, generally by liquids. Consequently, a branch of materials that are porous, liquid-sensitive, food, pharmaceuticals, wood lumber, concrete, consolidated powders, or in early stages of formation cannot be analyzed by ultrasound without adver...
متن کاملHigh-Temperature Pressure Transducers
Pressure sensing systems operating at temperatures >200 °C are required for a variety of presentand next-generation applications ranging from oil field instrumentation to turbine engine control. Quite often, part or all of the sensing system must be physically removed from the hightemperature environment. In some cases, pressure translating devices and capillary tubes are used to isolate the se...
متن کاملDevelopment of High-Performance BS-PT Based Piezoelectric Transducers for High-Temperature Applications
This paper focuses on the development of the new BiScO3-PbTiO3 (BS-PT) based piezoelectric ceramic transducers for high-temperature SHM applications. By controlling the PbO deficiency in the material system, we modify the lossy ferroelectric properties and enhance the piezoelectric responses from the intrinsic BSPT. The new in-house fabricated piezoelectric transducers can maintain comparably h...
