Abstract: PURPOSE: Provided is an apparatus for measuring the friction force in the biomaterial and an artifact which measures the friction force between the biomaterial constituting the animal organ and the various materials being operated in contact with the biomaterial exactly in an environment simulating in vivo environment. CONSTITUTION: The apparatus(10) for measuring the friction force in the biomaterial and an artifact comprises a stage(20), a sensing part for measuring the friction force(30), a specimen guide unit(40), a temperature control unit(50), a spray unit(60) and an amp(70). The specimen(80) is installed in the stage(20) so as to be inserted into and in contact with any biomaterial and artifact. The sensing part for measuring the friction force(30) responses to the strain and senses and signalizes the friction force according to the response. The temperature control unit(50) measures the temperature of the stage and specimen guide unit and keeps the temperature constant. The spray unit(60) makes pH of any biomaterial and artifact same and sprays the solution having the osmotic pressure same as the osmotic pressure of the biomaterial. The amp(70) amplifies a signal input from the sensing part for measuring the friction force and applies the signal to an external computer.
