Non-Equilibrium Dynamic Systems: Mechanisms of Active Pressure Rectification for Static Lift Generation

This position paper explores the theoretical possibility of generating a net upward force (lift) through the rectification of active pressure in non-equilibrium systems. By focusing on the interaction between active matter and asymmetric "ratchet" surfaces, the work proposes a mechanism to convert internal kinetic energy and stochastic fluctuations into directed mechanical work. The analysis bridges concepts from gyroscopic stability and molecular roto-vibrational dynamics to the "swim pressure" framework of active particles. Potential applications are discussed with a specific emphasis on micro-scale robotics (MEMS) and autonomous synthetic swimmers where viscous forces dominate. This study serves as a conceptual foundation for future experimental investigations into entropic-driven levitation.
