Flextensional Transducers with Shape Memory Caps for Tunable Devices
Source abstract
Abstract
Shape memory alloys were used as caps for the “cymbal” flextensional transducer. The active caps provide a tunable resonance frequency and a damage recovery mechanism associated with the alloy’s martensitic phase transformation. These two concepts were investigated and a 25% change in resonance frequency was observed for Ni-Ti alloy caps. It was also demonstrated that complete shape recovery could be achieved after hydrostatic pressures buckled the transducer caps. Cap deformation and recovery were demonstrated with profilometer and d h measurements.
