Abstract: Minimally invasive Surgery (MIS) is being rapidly applied into many procedures in order to reduce patients' pain, minimize the trauma especially in large incisions and promote faster recovery time. Visual and tactile sensory feedbacks are both necessary for surgeon's perception. Surgeons need the haptic feedback to guarantee the firm and adequate force between grasper-tissue interfaces. Research is active in the area of tactile sensor development for medical applications in order to secure a safe grasping and handling of tissues, as well as for diagnostic purposes. The Biomechatronics research group at RRC, NTU has developed a flexural mechanical macro-model whereby an array of strain gauges is fabricated by using MEMS technology. The strain gauges are installed on the flexing tip of this macro model to act together as sensing element. The transduced signal due to deflection of the sensing elements caused by exerted forces is acquired for signal conditioning and analysis.
