Dependency of properties of a tactile sensor on the electrode design and conductive ink layer

The paper presents electrical characteristics of conductive ink of type Graphit 33, acting as a converter between applied pressure and output electrical signal. It mentions basic properties of the ink, including the explanation of the principle of function. Further it describes the measurement process on tactile sensors with circular electrodes of various types and dimensions. It studies the dependency of electrical resistance of the ink on the applied pressure. Various setups with different ink layer thicknesses are compared and their suitability to act as pressure converter is finally discussed.
