About

Hatem ElBidweihy is a leading researcher in microrobotics and diamagnetic levitation, whose work bridges the gap between optical control and autonomous manipulation at the milli- and microscale. His core contributions lie in developing novel actuation and control methods for untethered robots, particularly through the photothermal manipulation of pyrolytic graphite (PyG). ElBidweihy’s research has fundamentally advanced the understanding of how optically-induced temperature changes can generate asymmetric diamagnetic forces, enabling precise translation of levitated objects. His 2019 paper on optical control of diamagnetically levitated PyG (9 citations) and his 2021 revision of photothermal actuation (8 citations) have become foundational references in the field, clarifying the underlying physics of this frictionless actuation mechanism. ElBidweihy’s most cited work, a 2020 study on autonomous microrobotic manipulation using visual servo control (13 citations), demonstrates his ability to integrate control theory with physical systems, achieving precise positioning of polymer beads. His 2023 paper on an optically powered milli-scale robot for nanoliter fluid delivery (4 citations) showcases a practical application with significant potential for biomedical and lab-on-a-chip technologies. Through his innovative use of optically absorbent coatings and projector-based control, ElBidweihy continues to push the boundaries of contactless, low-power robotic systems.
