A Review of Electric Impedance Matching Techniques for Piezoelectric Sensors, Actuators and Transducers

Abstract

Any electric transmission lines involving the transfer of power or electric signal requires the matching of electric parameters with the driver, source, cable, or the receiver electronics. Proceeding with the design of electric impedance matching circuit for piezoelectric sensors, actuators, and transducers require careful consideration of the frequencies of operation, transmitter or receiver impedance, power supply or driver impedance and the impedance of the receiver electronics. This paper reviews the techniques available for matching the electric impedance of piezoelectric sensors, actuators, and transducers with their accessories like amplifiers, cables, power supply, receiver electronics and power storage. The techniques related to the design of power supply, preamplifier, cable, matching circuits for electric impedance matching with sensors, actuators, and transducers have been presented. The paper begins with the common tools, models, and material properties used for the design of electric impedance matching. Common analytical and numerical methods used to develop electric impedance matching networks have been reviewed. The role and importance of electrical impedance matching on the overall performance of the transducer system have been emphasized throughout. The paper reviews the common methods and new methods reported for electrical impedance matching for specific applications. The paper concludes with special applications and future perspectives considering the recent advancements in materials and electronics.

Overview of Ultrasound Detection Technologies for Photoacoustic Imaging

“…Electrical impedance also affects the power transmission efficiency and SNR of the converted signal. Such electrical match is achieved using a matching network that can be realized using a material with high dielectric constant [49,50]. Moreover, a high dielectric constant is essential to improve the coupling coefficient [51].…”

Parametric Study of Bolt Clamping Effect on Resonance Characteristics of Langevin Transducers with Lumped Circuit Models

“…A numerical model is formulated to calculate the electrical input impedance of Langevin transducers over a certain frequency range. There are various equivalent models for representing the complex behavior of the piezoelectric material including Krimholtz, Leedom, and Matthae (KLM), Mason, Van Dyke, and Leach models [13][14][15]. Among them, the Mason model exhibits simpler electrical analogy than the others, consisting of two terminal impedances, a cross-impedance, and a clamped capacitance separated through an ideal transformer.…”
