Hand motion detection device and control method, rehabilitation device and autonomous control system

A hand motion detection device comprising:

• a motion detection portion adapted to be arranged on a finger joint of a first hand and configured for generating detection information for feedback of finger joint movement during a stretching movement and a flexion movement of a finger of the first hand, the motion detection portion being connected to a control portion, the motion detection portion configured for transmitting the detection information to the control portion, and the control portion adapted to generate an execution instruction according to the detection information,
• wherein the motion detection portion comprises a first detection unit and a second detection unit adapted to be arranged separately;
• wherein the first detection unit comprises a first conductive adhesive layer, the second detection unit comprises a second conductive adhesive layer, the first conductive adhesive layer and the second conductive adhesive layer are respectively arranged on opposite inner side walls of an elastic housing and spaced apart from each other so as to define a void space where no element is accommodated therein at a non-flexion state, and when the finger joint of the first hand is in a flexion state, a bottom face of the first conductive adhesive layer is configured to abut against an upper face of the second conductive adhesive layer to generate the detection information.
