Minimally Invasive Surgeries (MIS) are major operations through small incisions often using miniaturized high-tech systems, to minimize the trauma of surgical procedure. However such procedures deprive surgeons one of their most important ability-ability to touch and palpate. It also limits the dexterity, depth of perception and hand - eye coordination. The study focuses on the development of an effective mechanism of relaying the information across the surgical area to the surgeon through a tactile sensing feedback system. The design sensor system should be ergonomically sound, has high reproducibility of results so that it could be fitting for medical use. The project utilizes nine (9) circular tactile sensors formed in a 3x3 matrix to be interfaced data acquisition system through a Zilog Z8 Encore! 6421. The pressure distribution sensed by the feedback system will generate a 3D image to be shown in the constructed Graphical User Interface (GUI).
