Modeling of a new SMA micro-actuator for active endoscopy applications
Shape Memory Alloys (SMA) are good candidates to actuate endoscope heads but the cooling problem must be solved particularly in confined situations. For these reasons, a new SMA microactuator specially designed for active endoscopy applications has been developed in our laboratory. This work is a new step in the approach of using integrated thermoelectric cooling with SMA actuators. In fact, th...
متن کاملsynthesis of platinum nanostructures in two phase system
چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
Preisach Model Identification of a Two-Wire SMA Actuator
In recent years, the Preisach hysteresis model has emerged as the model of choice for the behaviour of many smart materials, such as shape memory alloys (SMA). This research treats the identiication of Preisach models for a diierential SMA actuator. The traditional identiication technique is applied, and several models are derived for the actuator. It is seen that the classical Preisach model i...
متن کاملA new control system for fast motion control of SMA actuator wires
This paper describes a new motion control system for actuators based on antagonistic-pair arrangements of electrically-heated SMA elements. Two different controllers have been tested, both of them incorporating a new rapid heating strategy that greatly increases the rate at which the elements can be heated without risk of overheating. Essentially, the current applied to the element is the lesse...
