In the last 10 years, shape memory alloys (SMAs) have been implemented in several high-performance applications requiring high competitive stresses, good biocompatibility, high work densities, high recoverable deformations, and high eco-friendly atmosphere. Nowadays shape memory alloys have become excellent candidates towards most general form i.e. MEMS/NEMS The minor application of 0.5mm SMA-based wire as a simple solenoid valve has been discussed in which SMA based conical spring in the helix form was employed. The advantageous purpose of valve to one way operated and can control the supply water, oil, liquid fuel and liquid refrigerant but choked by gravitational force/self weight, so It placed or installed anywhere in vertical position as per its limitations or reduction of cost. This solenoid valve can be called microelectromechicanical system (MEMS) because it is the integration of mechanical elements, sensors, actuators and electronics and fulfilled to small-scale precious requirements with high accuracy and precision. NiTi based thin film Shape Memory Alloys (SMAs) possess many desirable properties, such as high power density, large transformation stress and strain upon heating and cooling, superelasticity and biocompatibility. The actuation parameters included as average strain capacity, average running temperature avg. scale-load capability and wire-current and voltage during actuation were evaluated.
