However, the terms solid state motor stack and electroexpansive actuator. The actuation approaches are manifold and distributed as well as concentrated piezoelectric actuators were integrated in structural configurations. A silicone adhesive is adapted to adhere to the piezoelectric elements. Also embedded sensors and systems were developed for health monitoring, self-diagnosis of the structure and some of theses approaches were already implemented in civil buildings and

The motivation for these novel technology is about to alter the conventional way of engineering with its segregation of structuresĪnd systems. Features Drive Voltage Ranges: 0 to 75 V, 0 to 100 V, or 0 to 150 V Free Stroke Displacement Options from 5.2 m to 100. The latter application is highlyĪttractive for gapless and smooth aerodynamic elements. twist or bend and significantly deform a smart material plate.Īpplications of those active structures are of importance in the domain of aeronautic applications such as active vibration damping and aerodynamic control. Implemented into composite structures together with electrical wires and discrete sensors. Stack actuator Actuator Stroke output of a stack actuator is given by the following equation: ALd 33 V L (1) Where, AL is the stroke, d33 is the longitudinal piezoelectric coefficient, V is the driving voltage, t is layer thickness, L is the active length of the stack (the sum of all active layer. Solid-state actuator components such as piezo plates, low profile stacks, or shape memory alloy wires were

Smart structures strain induced structural actuation mechanism was developed. The stress which is generated by the smart material constituend transfer stress in the smart structure body and it will deform WOW! For actuation in Due to the commendable stress and strain of the smart material constituent od the smart structure, the shape Active materials such as piezoĪnd shape memory alloys were prepared and integrated into fibre reinforced plastics. Multifunctional structures have in addition to their load carrying function additional functions of actuation, sensing and energy harvesting. Smart Materials and Multifunctional Structures represent research streams which focus on the development of advanced multi-functional structures.
