The study of materials which can become deformed by light radiation has favoured the development of new types of interfaces and actuators. Indeed, by exposing materials made up of lead(chemical symbol Pb), lathanum(La), zirconium(Zr), titanium(Ti), known, from chemical symbols, like PLZT materials, to ultraviolet radiation, one can obtain deformations whereby these materials can be bent or elongated. These materials can therefore be used, for example, as microactuators for the opening and closing of pneumatic nozzles at the pneumatic valve pilot stage. In this study, the design and construction of a mechanical microactuator activated by a PLZT lamina are presented. This actuator amplifies the movement induced in the PLZT via an ultraviolet lamp, hence making it easier to use. The prototype has been studied using theoretical and experimental methods.
