The instrumented test system and the analysis for a novel tactile sensor are proposed to examine the material characteristic parameters on the basis of the indentation contact mechanics. A twin-strain-gage attached to the inner surface of a spherical glass-bowl-indenter senses in a differential manner the contact stress distribution beneath the indenter, and then allows to characterize the mechanical properties of the material indented. The indentation contact tests are conducted for more than thirty different materials including brittle ceramics, ductile metals, elastoplastic woods and papers, and viscoelastic foods. The test results suggest the potential applications of this tactile sensor to the mechanical characterizations of time-independent elastic/elastoplastic materials as well as time-dependent viscoelastic materials.
