About

Zhikai Liu is a researcher at the forefront of bio-inspired robotics and micro-electromechanical systems (MEMS), with a particular focus on the hydrodynamics of miniature aquatic robots. His most cited work, "Hydrodynamics Modeling of a Piezoelectric Micro-Robotic Fish With Double Caudal Fins" (2021), introduces an analytical model that links the displacement of a piezoelectric actuator to the oscillating angle of a dual-caudal fin system. This contribution is pivotal for designing efficient, untethered micro-robots for environmental monitoring and biomedical applications. By deriving the relationship between actuator motion and fin kinematics through a flexible four-bar mechanism, Liu provides a foundational framework for optimizing thrust and maneuverability in sub-centimeter-scale swimmers. With 14 citations, this paper has already influenced subsequent studies in soft robotics and piezoelectric propulsion. Liu’s work bridges theoretical modeling and practical micro-robotic design, offering a scalable approach to autonomous underwater vehicles. His research holds promise for advancing minimally invasive medical devices and aquatic surveillance systems, marking him as an emerging innovator in the intersection of robotics, fluid dynamics, and smart materials.
