Non-contact electron gun control of piezoelectric polymer thin film structures
Abstract
This paper summarizes research into the interaction of piezoelectric polyvinylidene fluoride (PVDF) structures with electron gun control. The experimental apparatus specific to the electron gun control of this structure is explained in detail. Equipment developed for the remote examination of the bimorph surface profile is also outlined. Experiments performed to determine the optimum electron beam characteristics for control are summarized. Clearer boundaries on the control output capabilities of the bimorph are resolved as well as the closed loop response. Further controllability analysis of the bimorph is outlined. In this research the bimorph response is tested through a matrix of control inputs of varying current, frequency, and amplitude. The results of these analyses are then examined. Research has shown that electron gun control can be used to make macro and nano control adjustments for PVDF structures. The control response and hysteresis are more linear for a small range of energy levels. Current levels needed for optimum control are established. The generalized controllability of a PVDF bimorph structure is shown.
