利用横向卡西米尔力，提出了一种由1个齿条和N个小齿轮组成的纳米级机械装置。通过扭转弹簧在小齿轮之间的耦合显示通过同步过渡协调它们的运动。对于每个设备，该系统可以在大于横向卡西米尔力的负载下工作。稳定同步状态的存在确保了系统可以完全协调地运行，而无需对所有特性（如弹簧常数、波纹幅度和齿条与小齿轮之间的距离）进行精细的微调。
The lateral Casimir force is employed to propose a nanoscale mechanical device composed of one rack and N pinions. A coupling between the pinions via torsional springs is shown to coordinate their motion through a synchronization transition. The system can work against loads that are greater than the lateral Casimir force for each device. The existence of a stable synchronized state ensures that the system could operate in full coordination without the need of delicate fine tuning of all the characteristics such as the spring constants, the corrugation amplitudes, and the distances between the rack and the pinions.
