We introduce a new mechanism and control system for wireless assistive finger training. The proposed mechanism and control system can provide natural finger flexion and extension via magnetic force and torque between a driving coil and a multi-link magnetic assist device placed on the fingers. The proposed mechanism is designed to allow normal movement while maintaining a natural finger shape, even when multiple magnets are applied to the fingers. Anatomical features were considered in the design to accommodate the angular changes between the fingers during hand extension and flexion. The magnetic force between the control system and the device on the hand allows extension and flexion of the fingers without the use of wires and electrical motors. The performance of the driving system and the magnetic device were verified through various simulations and experiments. A control program with motion tracking is also developed using LabView software. Hence, a wireless assistive finger training system is successfully realized.

具有电磁操纵系统的多链路磁铁装置，用于通过无线操作辅助手指运动

我们为无线辅助手指训练引入了一种新的机制和控制系统。所提出的机构和控制系统可以通过驱动线圈和放置在手指上的多连杆磁辅助装置之间的磁力和扭矩提供自然的手指屈曲和伸展。所提出的机制旨在允许正常移动，同时保持自然的手指形状，即使在手指上施加多个磁铁时也是如此。在设计中考虑了解剖特征，以适应手伸和屈曲过程中手指之间的角度变化。控制系统和手上设备之间的磁力允许手指伸展和弯曲，而无需使用电线和电动机。通过各种模拟和实验验证了驱动系统和磁性装置的性能。还使用 LabView 软件开发了带有运动跟踪的控制程序。因此，成功实现了无线辅助手指训练系统。
