In minimally invasive surgery, tactile feedback is lacking. A tactile display, consisting of a matrix of microactuators, represents tactile sensations on the ﬁngertip. Miniaturising powerful, dynamic and accurate actuators with a sufficient stroke is a considerable challenge.
This paper presents a proof of concept of a tactile display, based on microhydraulic actuators. A prototype with ﬁve taxels is designed, built and evaluated. The result is a light and compact display. It is mobile, has a stroke of 2mm, a spatial resolution of 2mm and can exert a maximal force of 0.5N. The actuation principle is innovative in the field of tactile displays and has a great potential.
