“…Researchers have noted polarization switching as a prominent cause of hysteresis [219]. Often, unsymmetric hysteresis and butterfly loops are obtained for 1-3 piezocomposites owing to internal buckling of piezoceramic fibers and external doping effects [220]. The electromechanical response of 1-3 piezocomposites had been observed to have a strong material dependence, which has solely been attributed to the piezoceramic fibers.…”

1-3 piezocomposites are excellent candidate materials for sensor, actuator and transducer applications owing to their remarkable dielectric properties, enhanced piezoelectric coupling constants and improved hydrostatic performance along with tunable acoustic impedance, high bandwidth and reliability. These materials find extensive use in aerospace, naval and biomedical sectors. 1-3 piezocomposites show a linear response when subjected to low electric fields and/or mechanical stresses. In such cases, linear models are sufficient for predicting their linear response. But, when high electro-mechanical loads are applied to these materials, they show nonlinearity owing to the presence of a passive and viscoelastic polymer matrix phase and inherent hysteretic damping in the piezoceramic fibers. This is when it becomes mandatory to understand both their linear and nonlinear behavior under different magnitudes of thermo-electro-mechanical static and dynamic loads. Linear response is modeled using linear piezoelectric constitutive equations. Nonlinearities in the form of hysteresis, depolarization, fatigue and creep occurs in 1-3 piezocomposites, which drastically affects their accuracy, precision and efficiency. In order to understand these nonlinearities, analytical and numerical methods have been proposed by several researchers in the past. An endeavor has been undertaken to review some of the attempts made earlier in these directions. Effective properties of these inhomogeneous media are evaluated through different hypotheses and assumptions. Most often, experimental routes are undertaken to predict material properties of 1-3 piezocomposites; nevertheless, the experimental evaluation of a few material properties is quite difficult and sometimes impossible, even with the best state-of-the-art experimental facilities. This motivates researchers to develop theoretical models to predict these material properties. Nonlinearities in 1-3 piezocomposites have been studied by researchers earlier with different theoretical modeling approaches and experimental techniques. This review paper is an endeavor to discuss the progress regarding the study of effective properties and nonlinearities in 1-3 piezocomposites in a coherent and holistic manner.

“…In the next step, the piezoelectric ceramics are polarized in silicon oil under high voltage which makes them highly piezoelectric, thus the piezoelectric ceramics can realize successful transformation between mechanical and electrical energy. The dopants can be divided into three main categories: i) donor doping, such as La 3+ , Bi 3+ , Nd 3+ doped in A sites, Nb 5+ in B sites [20][21][22], ii) acceptor doping, such as Mn 2+ , Fe 3+ , Al 3+ , Dy 3+ , Er 3+ doped in B sites [23][24][25][26], iii) isovalent doping, such as Sr 2+ , Ca 2+ , Ba 2+ in A sites, Sr 4+ in B sites [27,28]. PZT doping with donor ions, such as Y 3+ at A-site and Ta 5+ , Sb 5+ at B-site, reduces the concentration of intrinsic oxygen vacancies created due to PbO evaporation and compensates the hole formed due to lead vacancies, which in turn increases bulk resistance of the sample.…”

Perovskite solid solution (1-x)Pb(Zr0.52Ti0.48)O3-xY(Ta1/2Sb1/2)O3 ceramics (abbreviated as PZT-YTS, where x = 0, 0.01, 0.02, 0.03, 0.04 and 0.05) were synthesized by conventional solid state method. The phase structure, microstructure and corresponding electrical properties were studied. X-ray diffraction and Raman analyses show that tetragonal phase structure was obtained in all ceramics at room temperature. Scanning electron micrographs of the samples show uniform grain distribution and grain growth inhibition with the increase of doping content. The dielectric permittivity, dissipation factor, electromechanical coupling factor, Young modulus, mechanical quality factor, piezoelectric charge constant, actual density and piezoelectric voltage constant, for the ceramics with x = 0.04 were: ?r = 714.9, tan ? = 0.03345, KP = 0.635, Y = 10.528 ? 1010 N/m2, Qm = 622.254, d31 = 74.738 ? 10?12 C/N, ?a = 7.67 g/cm3 and g31 = 10.477 ? 10?3 m?V/N, respectively, which are optimal in comparison to other studied samples.

“…Thus, use of an extension sensor output is necessary to alleviate this problem and correctly control the actuator. While a number of techniques have been successfully used for actuator extension sensing based on capacitive, optical, and strain measurements [4][5][6], these techniques limit the miniaturization, complicate the system and increase the manufacturing cost. The simple integration of an extension sensor or use of self sensing actuators is highly desirable feature for many piezoelectric actuator applications [7][8][9][10][11].…”

Extension sensing of piezo actuators using time-domain ultrasonic measurement and frequency-domain impedance measurement

et al. 2011

There is a requirement for a simple and accurate extension sensing method for multilayer piezoelectric actuators for precision micro-positioning applications. This paper explains three different techniques of extension sensing for multilayer piezoelectric actuators, to provide a suitable method which involves primarily overcoming the inherent hysteretic behaviour of piezoelectric materials. The methods were; time domain ultrasonic pulse echo response for time travel of acoustic pulses, frequency shift response spectrum of an ultrasonic transducer and frequency shift in the impedance spectrum of the actuator alone. From the results, method of the frequency shift in the impedance spectrum of the actuator alone proved to be the most effective of the three. It was found that due to acoustic velocity changes under DC bias during the ultrasonic measurements, the inherent hysteretic behaviour was amplified in the other two methods when extension was plotted against time-shift and frequency shift. The results are presented and are discussed in terms of their suitability for precise positioning.
