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)
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)
This paper focuses on the development of novel actuators for a portable force feedback glove for, but not limited to, the simulation of open surgeries. A conceptual design of a chain-like actuator based on electroactive polymers is introduced. One actuator element of this chain was built in order to explore and optimize the actuator manufacturing process.(More)
We introduce the SmartMesh, a novel type of active structure capable of deforming actively its shape and thus being able to form objects. It is a new approach to find a solution to the difficulties that are encountered in the field of haptic interaction in virtual environments. The SmartMesh creates in real time the virtual objects as seen through head(More)
Compared with the double-difference relative positioning method, the precise point positioning (PPP) algorithm can avoid the selection of a static reference station and directly measure the three-dimensional position changes at the observation site and exhibit superiority in a variety of deformation monitoring applications. However, because of the influence(More)
