Functional rehabilitation robot based on flexible cable-driven hand movement

The invention provides a functional rehabilitation robot based on flexible cable-driven hand movement. The functional rehabilitation robot is composed of a driving unit and an execution unit connected with the driving unit; the execution unit comprises a metacarpophalangeal joint unit module for driving the finger root joints to move, a proximal interphalangeal joint unit module for driving the finger middle joints to move and a distal interphalangeal joint unit module for driving the finger end joints to move, and the driving unit comprises three sets of driving modules which work independently, have the completely same structure and correspondingly drive the metacarpophalangeal joint unit module, the proximal interphalangeal joint unit module and the distal interphalangeal joint unit module. According to the functional rehabilitation robot, not only can the three freedom degrees of the fingers except for the thumb and the movement angles of all the joints be met, but also a serial elastic driver is introduced, and therefore precise control over the joint moment is guaranteed; in addition, most parts are made through 3D printing, the weight of the acting fingers is greatly decreased on the premise that the strength is guaranteed; furthermore, the robot adapts to the individual difference of the finger length within a certain range.

Finger grasp rehabilitation training device

ActiveCN105310864AAssess progressEvaluation effectGymnastic exercisingChiropractic devicesHuman bodyStretch exercise
The invention discloses a finger grasp rehabilitation training device. The finger grasp rehabilitation training device is characterized in that a detection device comprises a torque sensor and an encoder, wherein the torque sensor is used for detecting torque positions when fingers are subjected to grasp training, and the encoder is mounted on a motor and used for detecting torque when the fingers are subjected to grasp training. The finger grasp rehabilitation training device has the advantages that the finger grasp rehabilitation training device integrates rehabilitation training with patient movement state detection and is capable of evaluating rehabilitation training progress and rehabilitation training effects effectively; active training and passive training of finger grasp can be achieved; different finger lengths are compensated by different finger sliders to enable the tail end of a finger mechanism to be on the same plane, and accordingly mechanism design is simplified; by moving in sliding grooves with different inclination angles, the fingers can be closed during grasp and can be spread during spreading; the finger grasp rehabilitation training device is capable of simulating normal grasping and spreading movements of a human body most effectively to improve rehabilitation effects, thereby being applicable to hemiplegia patients in the early, intermediate and advanced stages and being high in applicability.

Finger movement function rehabilitation apparatus driven by shape memory alloy wires

The invention discloses finger movement function rehabilitation apparatus driven by shape memory alloy wires, and belongs to the field of finger rehabilitation. The apparatus is composed of the shapememory alloy wires, ropes, an alloy wire connecting terminal, an inner-layer fabric, an outer-layer fabric, range extending mechanism supports, rings, and other parts. When the shape memory alloy wires are powered on, the temperature rises under the current heat effect to generate phase changes, the contraction is generated, then the ropes are pulled, and fingers are driven to bend and stretch. The fabrics on the inner layer and the outer layer have good elasticity, and the tightness degree of the whole fabric can be adjusted in cooperation with Velcro on an arm. In addition, a proper amount of silica gel is placed between each layer of fabric to improve the wearing comfort of the apparatus. A length of the alloy wires extending out of the connecting terminal at the tail end is adjusted toadapt to different finger lengths, so that the requirement of ergonomics is better met. The three Velcro are located on the wrist, the forearm close to the elbow, and the big arm close to the elbow respectively. The three Velcro can enable the rehabilitation apparatus to be better attached to the shape of the arm of the human body, so that range extending mechanisms more efficiently use the phasechange contraction of the SMA wires to drive the fingers to bend and stretch, and thereby the better rehabilitation effect is achieved.

Gallium nitride apparatus and manufacturing method thereof

The invention discloses a manufacturing method for a gallium nitride apparatus. The manufacturing method for the gallium nitride apparatus includes that firstly, defining a source region on a gallium nitride wafer; secondly, preparing an Ohmic contact and a grid metal insert finger on the source region; thirdly, preparing a source metal insert finger and a drain metal insert finger on the Ohmic contact; fourthly, preparing a grid electrode, a source electrode, a drain electrode and a back electrode; and finally, packaging inversely. The manufacturing method for the gallium nitride apparatus introduces the apparatus unit and matrix concepts, the insert finger length and width are effectively reduced, and the parasitic effect is reduced; and meanwhile, all the insert fingers are located in the same direction, and therefore, the source electrode width and drain electrode width can be reduced as far as possible so as to increase the proportion of the active region, and moreover, the grid electrode and the back electrode are embedded in the gap between the source electrode and drain electrode, the influence on the area of the source region of the apparatus can be neglected, and therefore, the effective area proportion is greatly improved, and the apparatus power density is increased. The inverse packaging method is good for agilely arranging the electrode interconnecting metal and improving the apparatus cooling performance.
