An ideal hand prosthesis should provide satisfying functionality based on reliable decoding of the user's intentions and deliver tactile feedback in a natural manner. The absence of tactile feedback impedes the functionality and efficiency of dexterous hand prostheses, which leads to a high rejection rate from prostheses users. Thus, it is expected that integration of tactile feedback with hand prostheses will improve the manipulation performance and enhance perceptual embodiment for users. This paper reviews the state-of-the-art of non-invasive stimulationbased tactile sensation for upper-extremity prostheses, from the physiology of the human skin, to tactile sensing techniques, noninvasive tactile stimulation, and an emphasis on electrotactile feedback. The paper concludes with a detailed discussion of recent applications, challenging issues, and future developments.

“…One aim of this paper is to use the penalty method to analyze the interaction between the heart tissue and a tactile sensor for minimally invasive surgery applications [Kalantari et al, 2010[Kalantari et al, , 2011a[Kalantari et al, , 2011b. Furthermore, since the frictional force exists in all contact processes, it is important to consider friction effect to get more realistic result.…”

This paper discusses the effect of friction in tool-tissue interaction of surgical simulation. The focus of this research is on mitral valve repair by robot-assisted surgery (RAS) method with tactile feedback. Heart tissue is considered to be touched by a tactile sensor with considering the friction effect. A regularized Coulomb law analogous to elastoplastic theory is used to represent the friction. Since the heart tissue is subjected to repeated loading condition, a generalized standard solid chain is chosen for modeling the heart tissue. To implement the generalized standard solid chain in finite element analysis (FEA), a new splitting strategy is presented. The splitting strategy avoids the complicated conversion procedure from creep function to relaxation function by dividing the total problem into several subproblems. The penalty method is used in the derivation of continuum model for the interaction between the tactile sensor and the tissue. By performing linearization for the continuum model, the discrete model for the FEA is obtained. Numerical results are obtained by using the constitutive parameters of tissue and friction coefficient, which were found experimentally.

“…Integration of the novel sensors such as thin film tactile sensors to the surgical tools and creating training platforms equipped with these tools can benefit novice surgeons to enhance their skills and senses [1][2][3]. Thin film tactile sensors can be used for measuring contact force and pressure in real-time for minimally invasive surgery [4][5][6][7][8]. Integration of a thin layer to tool alters contact characteristics in despite of its advantages.…”

This study investigates coefficient of friction of flat-tipped laparoscopic surgery tool (bowel grasper) in an ex vivo experiment in order to identify the approximate coefficient of friction between laparoscopic tool and the organic sample. The estimation of friction force is essential for ensuring safe grasping. The friction tribometer and the laparoscopic grasper setup were the two experimental setups to conclude the friction of the tool in the absence tactile sensor. The measurement of the pinch force and estimation of the friction force from the measured pinch force and the coefficient of friction is suitable for novice surgeon training.
