About

Lijie Sun is a researcher specializing in the mechanics and modeling of soft smart materials, with a particular focus on dielectric elastomers (DEs) and their application in soft robotics and actuator systems. Their work centers on understanding the complex electromechanical behavior of these polymer-based materials, which can generate large displacements under electrical stimulation — a property that makes them highly attractive for next-generation robotic and engineering systems. Sun's most significant contribution lies in developing sophisticated constitutive models to capture the viscoelastic behavior of dielectric elastomers. Their 2021 paper introducing the Kelvin Voigt-Generalized Maxwell framework has garnered 32 citations, establishing a rigorous theoretical foundation for predicting the time-dependent mechanical response of DEs. Subsequent work has extended this modeling approach to examine dissipative dynamic performance and energy efficiency in DE actuators, as well as creep behavior in cylindrical actuator geometries — both critical challenges for translating these materials into practical devices. Collectively, Sun's research addresses a fundamental gap between theoretical material science and real-world actuator engineering, providing tools that enable more accurate design and optimization of soft robotic components. Their growing citation record reflects an emerging influence in the rapidly evolving field of soft active materials.
