“…In this section, fundamental opto-electromechanics (photostriction or opto-piezoelectricity) of distributed photostrictive optical actuator systems are discussed. This photostrictive behavior or opto-piezoelectricity is a photodeformation process which includes two opto-electromechanical effects: the photovoltaic effect and the converse piezoelectric effect (Brody 1983, Uchino 1990, Fridkin 1979, Tzou 1993b). The photodeformation and photo-induced actuation effect of distributed photostrictive actuators are formulated and governing equations derived.…”

Optically driven actuators can introduce remote actuation and control effects without any hard-wire connections. In this study, photostrictive (opto-piezoelectric) characteristics and photodeformation of distributed photostrictive optical actuators are investigated and a parametric study of design parameters is conducted. Photodeformation induced by the photostrictive (opto-piezoelectric) effect (a combination of the photovoltaic effect and the converse piezoelectric effect) is discussed and its two-dimensional (2D) constitutive relations are presented. 2D equivalent control forces and moments induced by the photodeformation effect of distributed actuators are formulated, and system governing equations derived. Static and dynamic applications are discussed, and simulation studies of design parameters are conducted and evaluated.

“…Feasibility and performances of photostrictive actuators applied to one-dimensional (1-D) systems have been demonstrated over the last two decades [3][4][5][6][7][8][9][10][11]. Two-dimensional (2-D) plate type photostrictive actuators and fundamentals about the coupling of the opto-piezo-thermoelasticity fields were also investigated [12,13].…”

Photostrictive materials, such as PLZT, which have the ability to convert high-energy light into mechanical motion, are emerging as new actuation materials. In contrast to the conventional transducers, photostrictive materials can produce actuation strains resulting from irradiation from certain wavelength light, which are immune from the electromagnetic interferences. And this photo-driven process is the photodeformation effect. In this paper, characteristics of the photodeformation effect are calibrated. The light intensity, the temperature and the voltage leakage's influences to the characteristics of the photostrictive actuator are also evaluated. Since actuator's location is one of the critical issues to decide the structural vibration control effectiveness, the modal control action and optimization of actuator placement for distributed control of a hybrid patched optical actuator/beam is investigated. An effective method to achieve the best vibration control is inferred from the parametric study.
