A New Anti-Rotational Bio-Inspired Structure in Bicycle Helmet

This study investigated innovative bicycle helmet designs inspired by the unique structural features of horsetail plants and the human spine, aiming to reduce rotational acceleration, a key factor in severe brain injuries. Simulation results demonstrated that the developed bio-inspired lattice structure reduced rotational acceleration by 44% compared to traditional liners. Experimental tests further validated the effectiveness of this design, showcasing its potential for enhancing head protection. Future research will focus on refining these findings to improve helmet performance in real-world scenarios.
