The invention provides a wearable assistance finger based on myoelectric control. The wearable assistance finger comprises an under-actuated simulated human finger, a magnetic
coupling interface, a
rehabilitation assistance connector, a myoelectric collecting array, a
servo motor and a
control system, wherein the under-actuated simulated human finger adopts a mixed
driving mode of connecting rod driving and driving
tendon driving, and the requirement of moving the patient finger joints is sufficiently met. Meanwhile, a control method of the wearable assistance finger based on myoelectric control is provided. The wearable assistance finger has the advantages of simple structure, light weight and good reliability. A
force sensor and a
position sensor are connected onto a driving
tendon, the force and the position for driving the finger to move can be obtained through the telescopic movement of the driving
tendon, and the quantification index can be provided for the
rehabilitation process. The wearable assistance finger has the advantages that the structure is simple, the cost is low, the operation and the wearing are convenient, the man-
machine interaction performance is good, the obstruction caused by
muscle and joint rigidity can be effectively overcome, the patient can obtain effective
rehabilitation treatment, and better application prospects are realized in the fields of finger rehabilitation and the like.
