In the present work we attempt to demonstrate the potential advantages of inserting an electrically tunable q-plate as phase mask in the design of a vector vortex coronagraph. The possibility of electrically adjusting the operation wavelength of the phase mask, joined with highly accuracy patterning capabilities, allow to push imaging contrast as high as possible. Azimuthally selective masks can be also envisaged, based on geometric phase, allowing to enhance contrast only where this is actually needed.
