An Ion Discharge-Driven Thruster Based on a Lithium Niobate Piezoelectric Transformer.

ABSTRACT: Microrobots, characterized by their small size, flexibility, and portability, have a diverse range of potential applications. However, microrobots' actuation (piezoelectric ceramics, dielectric elastomers, ion winds, etc.) often requires a high voltage, typically hundreds of volts. The lithium niobate transformer (LNT), a piezoelectric voltage transformer, presents a promising solution for miniaturizing high-voltage power supplies due to its compact size, low weight, and high step-up ratio. This study explores the effects of structural parameters and external circuits on the resonant frequency and step-up ratio of the LNT through numerical simulations and experiments. The results indicate the following: (1) the second-order longitudinal vibration frequency of the lithium niobate (LN) plate
