About

Jarod C. Gagnon is a leading researcher in soft robotics and smart materials, with a focus on liquid crystal elastomers (LCEs) for untethered actuation. His major contribution is the development of an untethered soft robot powered by LCE actuators, which are thermally triggered via Joule heating and controlled wirelessly through Bluetooth. This work, published in 2021 and cited 57 times, demonstrated a remarkable ∼5 N force pull capacity per LCE and a >20% repeatable strain over more than 100 cycles, showcasing the durability and practicality of LCE-based systems. Gagnon’s innovations address a critical challenge in soft robotics: achieving autonomous, wireless operation without bulky external power sources. By integrating onboard power and control, his research paves the way for applications in search-and-rescue, medical devices, and adaptive structures. His work stands out for its combination of high-force output, repeatability, and untethered functionality, making it a foundational reference in the field. Gagnon’s achievements highlight his ability to bridge materials science and robotics, offering a compelling vision for next-generation soft machines that are both powerful and autonomous.
