Optimal Design of a Shape Memory Alloy Actuator for Microgrippers
In this paper, a modular microactuator based on shape memory alloy (SMA) actuation to drive the joints of a microgripper is described. Its design is a combination of two SMA actuators installed on the links of a special mechanism : one of them drives the rotation of the joint and the other one produces the necessary force to manipulate objects. An accurate model of the thermo-mechanical behavio...
متن کاملShape memory alloy actuators and their reliability
We have developed two types of shape memory alloy (SMA) actuator and estimated the long-term reliability of SMA microcoils. A tube type tip articulator consists of 4 sets of SMA microcoil (wire diameter: 0.125 mm, coil diameter: 0.5 mm) for driving source and super elastic alloy (SEA) microcoils (wire diameter: 0.1 mm, coil diameter: 0.5 mm) for bias springs, support plates and flexible outer t...
متن کاملWet Shape Memory Alloy Actuators for Active Vasculated Robotic Flesh
− A new type of actuator is presented where Shape Memory Alloy (SMA) wires are embedded within artificial “blood vessels.” Fluid flowing through vessels allows the SMA wires to be rapidly cooled by convection, resulting in greater bandwidth than ordinarily possible. Combinations of electric, fluidic, and thermal inputs can be used to control the contraction/extension of the SMA wires within the...
متن کاملShape memory alloy micro-actuators for medical applications
Most of the current ’applications’ of microelectromechanical systems can be found in the sensor field. The development of micro-actuators is severely hindered by the low power-to-volume ratio of most actuator technologies. Most of the presented micromotors also require reduction gearing and suffer from wear or fatigue problems. Shape Memory Alloy (SMA) actuators offer the advantage of extremely...
متن کاملShape Memory Alloy and Elastomer Composite MEMS Actuators
A process for fabrication of shape memory alloy MEMS actuators on a elastomeric polymer substrate is described. These actuators are designed for use on innovative soft body robots. Patterned shape memory alloy (nitinol) is sputter deposited on a polyimide mesh structure. The mesh substrate acts as a bias spring to de-twin the shape memory alloy in the martensite phase. Significant portions of t...
