2011	Ahmad Atieh (2011) FEM Analysis of the Interaction Between a Piezoresistive Tactile Sensor and Biological Tissues In: International Conference on Bioinformatics, Computational Biology and Biomedical Engineering 106-110 Amsterdam, Netherlands,: Abstract: The present paper presents a finite element model and analysis for the interaction between a piezoresistive tactile sensor and biological tissues. The tactile sensor is proposed for use in minimally invasive surgery to deliver tactile information of biological tissues to surgeons. The proposed sensor measures the relative hardness of soft contact objects as well as the contact force. Silicone rubbers were used as the phantom of biological tissues. Finite element analysis of the silicone rubbers and the mechanical structure of the sensor were performed using COMSOL Multiphysics (v3.4) environment. The simulation results verify the capability of the sensor to be used to differentiate between different kinds of silicone rubber materials. Notes:

The sensing element of the sensor relies on a piezoresistive material. The proposed sensor measures contact force as well as the relative hardness of soft contact objects. A prototype of the sensor has been built, calibrated, and tested. Experimental test results confirm the ability of the sensor to dis-tinguish between two different elastomeric materials. Such mate-rials resemble two different biological tissues. Notes:
