After a wrap-up in the human physiology and an overview on physical principles, this paper introduces four novel types of actuators for haptic feedback devices based on electroactive polymers, which were developed and evaluated for their suitability for haptic feedback devices. The electroactive polymers show many promising properties, such as big(More)
In this paper, we present a new portable force feedback device for surgery simulations. Dielectric elastomer spring roll linear actua-tors for this device were manufactured, and characterized via passive tensile tests and active isometric tests. The actuators exhibited a maximum force of 7.2 N, and a maximum elongation of 31%. Due to the high driving(More)
