In minimal invasive surgery high sensory palpation of the organs is largely lost. It is the purpose of this work to recover tactile sensing for the surgeon. To achieve this goal, a new tactile optical pressure sensor has been developed which allows to display 64 measuring points on a 0.64 cm2 surface area with a digital resolution of 12 bits. The sensor has been conceived for application in laparoscopic grasping forceps and can also be integrated into a sensing rod, both 15 mm in outside diameter. This optical sensor allows us to display graphically indurations spread in the tissue. Furthermore, the measured values serve to activate a vibrotactile display unit for tactile feedback onto the surgeon's fingertip. In order to obtain further information about the requirements for an analog tactile display, an actuatorarray with 144 pins on a 4 cm2 surface area was built. The array allows various test objects to be recognized in a true scale presentation by exploratory movements of the fingers.
