    Abstract

    We are demonstrating a novel plasma spraying method, i.e. Direct Write Thermal Spray for strain gauge manufacturing. Sprayed and laser finished strain gauges were subjected to cyclic loading and performance was compared to commercial strain gauges. The main differences between demonstrated sprayed gauges and commercial gauges are in sensitivity and zero point drift. It is suggested that these differences can be significantly reduced. Thus, it is suggested that Direct Write Thermal Spray is a potential new method for strain gauges integration within strained structures for monitoring purposes
