Conventional cold and warm gas thrusters with low specific impulses and thrust greatly limit the capability of nanosatellites to conduct meaningful plane and attitude changes in space. This work shows that a novel flexible microplasma thruster (FPT)

The atmospheric pressure plasma jet (APPJ) has a merit to treat curved or 3D surface without using a ground electrode but nonetheless limits applications for expanding treatment area due to the localized ionization energy induced by the propagation a
