About

Stefan Begej is a pioneering figure in the field of robotic tactile sensing, whose work has fundamentally shaped how machines can “feel.” His primary research focuses on the development of optical tactile sensors, specifically designed to enhance dexterous robotic manipulation. Begej’s major contribution lies in his innovative application of the principle of frustrated total internal reflection (FTIR), where an opaque elastic membrane pressed against an optical surface creates a greyscale image directly related to contact strain. His seminal 1988 paper, *Planar and finger-shaped optical tactile sensors for robotic applications*, has garnered 151 citations, establishing a foundational framework for the field. This work, alongside his earlier 1985 introduction of an optical tactile array sensor (19 citations) and his later 2003 development of a high-density, fingertip-shaped sensor (16 citations), demonstrates a sustained trajectory of innovation. By moving from planar arrays to biologically-inspired fingertip shapes, Begej directly addressed the critical need for high-resolution, compliant sensing in robotic hands. His research remains a cornerstone for engineers and researchers seeking to bridge the gap between simple touch and true tactile intelligence in robotics.
