During this student’s 16-week internship at NASA’s Jet Propulsion Laboratory in Pasadena, California, research on piezoelectric technologies was conducted through two different projects. Concepts for Ocean worlds Life Detection Technology (COLDTech) is an effort to create an under-ice acoustic communication network using piezoelectric transducers. Heaters for the transducers were designed and tested so the transducers could be quickly retrieved after having been frozen in ice for acoustics testing. Seven units were assembled and used during a field test at Matanuska Glacier in Alaska. All heaters worked without fail and the field test was a success. The second project, Image Retrieval in Segments (IRIS), focused on surface parallel mirror actuation using piezoelectric stacks bonded into flexures. To characterize the performance of the actuators, several tests were performed. First, an open circuit thermal strain analysis was conducted on the stacks/flexures when taken down to 100K using liquid nitrogen and an environmental chamber. Using LABview scripts, creep and crosstalk were then tested on 42 actuators bonded to the back of an aluminum mirror segment. Finally, a parametric flexure was modelled in SolidWorks for frequency simulation. The results of the IRIS tests were presented at the International Society for Optics and Photonics (SPIE) Smart Structures Conference in March 2024 by Dr. Stewart Sherrit and George Lamb.
