    Abstract: Various embodiments of the present technology generally relate to robotics and prosthetics. More specifically, some embodiments of the present technology relate to multi-modal fingertip sensors with proximity, contact, and for localization capabilities. Various embodiments of the present technology provide for a novel multi-modal tactile sensor which comprises an infrared proximity sensor and a barometric pressure sensor embedded in an elastomer layer. Signals from both of these sensors can be fused to measure proximity (0-10 mm), contact (0N), force (0-50N) and localize impact at five spatial locations and three angles of incidence. Gaussian processes in a regression setting can be used to obtain calibrated force measurements with an R-squared value of 0.99. Supervised machine learning approaches can be used to localize the position and direction of probing with classification accuracies of 96% and 89% respectively.
