About
Nicholas Kellaris is a pioneering soft robotics researcher whose work has fundamentally advanced the field of electrohydraulic artificial muscles. He is best known as a primary architect of HASEL (Hydraulically Amplified Self-Healing Electrostatic) actuator technology — a breakthrough class of soft actuators that mimic biological muscle with remarkable fidelity. His landmark 2018 paper introducing Peano-HASEL actuators, which linearly contract upon electrical activation, has garnered over 530 citations and established a new paradigm for muscle-like robotic motion. Kellaris has consistently pushed this technology forward, developing accessible fabrication toolkits, analytical design models, and bioinspired variants such as spider-inspired electrohydraulic joints capable of fast, forceful movement. His research spans mechanical modeling, multifunctional sensing, and shape-display systems, reflecting a comprehensive engineering vision. Notably, his 2023 work on biodegradable electrohydraulic actuators demonstrates a forward-thinking commitment to sustainable robotics. With over 1,200 cumulative citations across his body of work, Kellaris has positioned himself as a defining voice in next-generation soft robotics, bridging fundamental materials science with real-world applications in prosthetics, human-robot interaction, and autonomous systems.
