International audience. This paper describes design improvements of a friction reduc-tion based tactile device, which yields to reduction of the supply power. We first evaluated the power consumption of four different plates. We found that a convenient design could cut the power losses down by 90%. To explain these changes we propose a modelling of the dielectric losses in the piezoelectric actuators and of the vibration amplitude.
