Abstract

To achieve transducing materials of high electromechanical coupling factor, high adaptability and high compatibility, this paper proposes a semi-flexible 1–1–2-type nested composite (1–1–2-type composite) composed of piezoelectric ceramics, epoxy resin and silicone rubber. Based on the uniform theory and the mixed field theory, an equivalent parameter model of 1–1–2-type composites is established, and the influence of structural parameters on the resonance parameters of the 1–1–2-type composites are analyzed. Finite element simulation is conducted on the 1–1–2-type composite to verify the effectiveness of the equivalent parameter model. The “dice-fill” technique is used to fabricate 1–1–2-type composite samples. The results show that the 1–1–2-type composite has a significant thickness vibration mode. These 1–1–2-type composites exhibit a high thickness electromechanical coupling factor, with an average value of 0.69 across all samples and a peak value reaching 0.72. Compared to traditional 1–3-type composites, this improvement can be as high as 20 %. 1–1–2-type composite combines the advantages of high electromechanical properties, high conformability, and high compatibility, along with good resistance to hydrostatic pressure, making it highly promising for the development of innovative multifunctional curved transducers and their arrays.

一种具有三分量嵌套结构的半柔性1-1-2型压电复合材料

为实现高机电耦合系数、高适应性和高相容性的换能器材料，本文提出了一种由压电陶瓷、环氧树脂和硅橡胶组成的半柔性1-1-2型嵌套复合材料（1-1-2型复合材料）。基于均匀理论和混合场理论，建立了1-1-2型复合材料的等效参数模型，分析了结构参数对1-1-2型复合材料共振参数的影响。对1-1-2型复合材料进行了有限元仿真，验证了等效参数模型的有效性。采用“骰子填充”技术制备1-1-2型复合材料样品。结果表明：1 - 1 - 2型复合材料具有明显的厚度振动模式；这些1-1-2型复合材料具有较高的厚度机电耦合系数，所有样品的平均值为0.69，峰值达到0.72。与传统的1 - 3型复合材料相比，这种改进可以高达20% %。1-1-2型复合材料结合了高机电性能、高一致性、高兼容性以及良好的静水压力抗力等优点，在新型多功能弯曲换能器及其阵列的开发中具有很大的应用前景。

期刊介绍： Sensors and Actuators A: Physical brings together multidisciplinary interests in one journal entirely devoted to disseminating information on all aspects of research and development of solid-state devices for transducing physical signals. Sensors and Actuators A: Physical regularly publishes original papers, letters to the Editors and from time to time invited review articles within the following device areas: • Fundamentals and Physics, such as: classification of effects, physical effects, measurement theory, modelling of sensors, measurement standards, measurement errors, units and constants, time and frequency measurement. Modeling papers should bring new modeling techniques to the field and be supported by experimental results. • Materials and their Processing, such as: piezoelectric materials, polymers, metal oxides, III-V and II-VI semiconductors, thick and thin films, optical glass fibres, amorphous, polycrystalline and monocrystalline silicon. • Optoelectronic sensors, such as: photovoltaic diodes, photoconductors, photodiodes, phototransistors, positron-sensitive photodetectors, optoisolators, photodiode arrays, charge-coupled devices, light-emitting diodes, injection lasers and liquid-crystal displays. • Mechanical sensors, such as: metallic, thin-film and semiconductor strain gauges, diffused silicon pressure sensors, silicon accelerometers, solid-state displacement transducers, piezo junction devices, piezoelectric field-effect transducers (PiFETs), tunnel-diode strain sensors, surface acoustic wave devices, silicon micromechanical switches, solid-state flow meters and electronic flow controllers.
