“…V t This means that the photo-induced deformation lags behind the voltage, which is observed in our experiments, as well as in some other reports [19,20]. Therefore, the mathematical model proposed in this paper can explain the hysteresis phenomenon and the variation trend of the photo-induced voltage and deformation very well.…”

The primary purpose of this paper is to propose a mathematical model of PLZT ceramic with coupled multi-physics fields, e.g. thermal, electric, mechanical and light field. To this end, the coupling relationships of multi-physics fields and the mechanism of some effects resulting in the photostrictive effect are analyzed theoretically, based on which a mathematical model considering coupled multi-physics fields is established. According to the analysis and experimental results, the mathematical model can explain the hysteresis phenomenon and the variation trend of the photo-induced voltage very well and is in agreement with the experimental curves. In addition, the PLZT bimorph is applied as an energy transducer for a photovoltaicelectrostatic hybrid actuated micromirror, and the relation of the rotation angle and the photoinduced voltage is discussed based on the novel photostrictive mathematical model.

“…This expression states the nonlinear dependence of strain on the incident light intensity and varies with light penetration depth in the thickness direction. They have also experimentally measured the time-dependent response of photovoltage, photocurrent, and transverse displacement of PLZT when poled in thickness direction (Luo and Tong, 2011, 2012). Elimination of residual photovoltage and photoinduced deformation can lead to improving the response of PLZT (Wang et al, 2015).…”

Coalesce of photovoltaic effect with converse piezoelectric effect will turn into a photostrictive phenomenon. The current study conceptualizes a 1-3 photostrictive composite consists of a photovoltaic polymer as matrix and fibers of piezoelectric material. The proposed artificial photostrictive composite is capable of replacing lead-based naturally occurring photostrictive material, not only opening a potential for new applications but also caters to tailor the desired properties. Present study employs poly{4,8-bis[5-(2-ethyl-hexyl)thiophen-2-yl]benzo[1,2-b:4,5-b’]dithiophene-2,6-diyl-alt-3-fluoro-2-[(2-ethylhexyl) carbonyl] thieno[3,4-b] thiophene-4,6-diyl} (PTB7-Th) as organic photovoltaic polymer and Pb(Mg1/3Nb2/3)O3-0.35PbTiO3 (PMN-35PT) as the fibers. A representative volume element technique (RVE) is employed to embrace the local variation of multi-physics properties. The actuation response of cantilever and simply supported beam bonded to photostrictive composite patch is accurately predicted by finite element method, while discretizing the structure with degenerated shell element. Photostrictive composite with 60% volume fraction of fibers, arranged in square pattern have deflected the cantilever tip to 1.95 mm. Therefore, we provide 1-3 photostrictive composite as a solution for future wireless and lightweight vibration control applications.

The lanthanum-doped lead zirconate titanate ceramic is a well-known photostrictive material and has been studied extensively as wireless photo-controlled microactuators for its characteristic of photostrictive effect. However, the hysteresis phenomenon between photovoltage and photo-induced deformation has seriously hindered the application of the high-frequency dynamic field. The primary purpose of this article is to propose a photo response torsion actuator driven by opto-electrostatic hybrid driving method based on lanthanum-doped lead zirconate titanate ceramic to achieve the goal of rapid response regardless of the hysteresis phenomenon. To this end, this study observed the driving voltage, the relationship between the photovoltaic voltage of lanthanum-doped lead zirconate titanate ceramic and the deflection of the actuator, and the influence of different loads on driving characteristics through a series of experiments. From these experiments, the results indicate that when lanthanum-doped lead zirconate titanate ceramic is irradiated by ultraviolet light, the photovoltaic voltage with load is lower than that without load. The trend of deformation curves is in agreement with the trend of the driving voltage curves under different loads conditions. And the deformation of torsion actuator increases with the increase in light intensity. Therefore, the photo response torsion actuator driven by the opto-electrostatic hybrid driving method can control the deformation with rapid response speed effectively; meanwhile, the hysteresis phenomenon can be ignored.
