The use of shape memory alloys (SMAs) in construction and housing

Abstract: This chapter presents applications of shape memory alloys (SMAs) in various environmentally conscious technologies and products such as recycling, reducing noise and energy conservation. The underfloor ventilation hole with a thermal actuator composed of the SMA and bias springs can automatically open and shut depending on air temperature. SMAs have been utilized as noiseless rock breakers. The easy-release screw using a shape memory washer is effective in improving recycling efficiency in the consumer electronics industry.
