VoiceControlled Flexible Exotendon (FLEXotendon) Glove For Hand Rehabilitation In this work, we propose a voicecontrolled hand rehabilitation device driven by exotendons. A smartphonebased voice recognition system interprets user intention and is utilized for various grasping tasks. A bioinspired tendon routing mechanism provides fourdegreesoffreedom (DoFs) across the thumb, index finger, and middle finger. A novel thumb sleeve design is presented for stable thumb movement. The exoskeleton is fabricated from polyurethane rubber and rigid 3Dprinted parts to provide formfitting properties while constraining tendon motion. Twisted string actuators and spring units provide active flexion and passive extension, respectively. The compact nature of the actuation unit allows for placement on the forearm, improving the portability of the system. The voice control system allows for easy user manipulation and accessibility and may improve rehabilitation efficiency. The performance of the tendon routing and thumb sleeve design were experimentally evaluated and voice control system was evaluated with various grasping tests.

A Design of Hand Rehabilitation Exoskeleton Mechanism Adapted to Different Finger Lengths Stroke can cause the neurological function of the brain hemisphere or brain stem to be blocked, which in turn causes partial loss of function of the hands and feet. This paper presents a hand rehabilitation exoskeleton mechanism with an adjusted locking device to adapt to different finger lengths. The biological characteristics of the finger are analyzed to obtain the motion parameters of the finger. The presented mechanism is optimized for its rod length by the fgoalattain function optimization method. This is done for the exoskeleton mechanism could drive the finger to reach the ideal bending angle. A proofofconcept plastic prototype was fabricated, and the experimental results demonstrates the potential of this mechanism.
