Piezo induced deformations are proposed as a means of achieving a higher degree of on-orbit surface accuracy of inflatable antennas. A series of tests were performed on an inflated circular membrane and an inflated tube, both made of off-theshelf piezo film. The same configurations were also analyzed to validate the tests. The concept was demonstrated qualitatively in spite of a discrepancy between the analysis and test results, most likely due to inaccurate knowledge of the piezoelectric coefficients of the film.
