Design and Experimental Analysis of Gripper for Shape Memory Alloy Actuation

In the developing technological scenario, the researchers are looking for a material that is highly reliable and having unique property to retaining its shape in certain high and low temperature. The shape memory alloy is having prescribed qualities and one of its unique property is to recover shape upon heating can be effectively packaged into compact, light, powerful silent actuators to replace DC motors and electrical motors. The objective of the paper is to design, fabricate and analysis of gripper on the principle of slide crank mechanism, which is actuate with Shape Memory Alloy spring. The characteristics targeted in this experiment are of ensuring mechanical actions if stimulated with electrical current allows the development of simple, more compact and reliable actuators.
