When the watchband structure is worn by a wearer, the first elastic layer 1 may be located on a side (inner side) close to (or attached to) the skin of the user (wearer), and the second elastic layer 3 may be located on a side (outer side) away from the skin of the user (wearer), that is, the first elastic layer 1 and the second elastic layer 3 are located on opposite sides of the elastic circuit 2, so that the first elastic layer 1 and the second elastic layer 3 can form protection to the elastic circuit 2 from the opposite sides, and prevent accidental injury to the elastic circuit 2 during use, thereby ensuring normal operation of the detection electrode 23 in the elastic circuit 2. The thickness of the second elastic layer 3 is generally set to be greater than that of the first elastic layer 1, for example, the thickness of the first elastic layer 1 may range from 0.3 mm to 0.5 mm, and the thickness of the second elastic layer 3 may range from 1.0 mm to 1.5 mm, so as to ensure the stretchability of the watchband structure and also enhance the protection capability of the second elastic layer 3 to the elastic circuit 2.

For example, the first elastic layer 1 and the second elastic layer 3 may be made of elastic materials such as elastic nylon, elastic rubber, and elastic silica gel, and the elastic circuit 2 may be made of TPU polyurethane (thermoplastic polyurethane elastomer).
In addition, set up first elastic layer 1, second elastic layer 3 and elastic circuit 2 all have elastic deformation volume for the watchband structure that forms by first elastic layer 1, second elastic layer 3 and elastic circuit 2 can be stretched under the exogenic action, also makes this watchband structure under wearing the state, and the inside detection electrode 23 can comparatively accurately detect user's hand muscle crowd signal, has also reduced EMG (electromyography) signal detection's complexity.

As shown in fig. 1, the circuit layer 22 is located on the side of the elastic carrier film layer 21 near the first elastic layer 1, that is, the circuit layer 22 is located near the user, for example, the circuit layer 22 may be implemented by a nano conductive paste, which is made of a material having a predetermined elasticity (typically, weak elasticity). In this embodiment, one or more of silver-based nano conductive paste, carbon-based nano conductive paste, and copper-based nano conductive paste may be used, and the nano conductive paste is attached to the elastic carrier film layer 21 through printing, 3D printing, or spraying, so as to form the elastic circuit 2. Wherein, the thickness range of the elastic film-carrying layer 21 can be 0.1 mm to 0.2 mm, and the thickness range of the circuit layer 22 can be 0.01 mm to 0.05 mm, so as to ensure the tensile property of the watchband structure and facilitate the light and thin development of the watchband structure.

Optionally, the circuit layer 22 is formed by attaching nano conductive paste to the elastic carrier film layer 21. Wherein the nano-conductive paste is composed of a material having a predetermined elasticity (generally weak elasticity). In this embodiment, one or more of silver-based nano conductive paste, carbon-based nano conductive paste and copper-based nano conductive paste may be used, and the nano conductive paste is attached to the elastic carrier film layer 21 by printing, 3D printing or spraying to form the elastic circuit 2, so that the elastic circuit 2 also has an elastic deformation amount, and the elastic circuit 2 is convenient to adapt to the stretching of the first elastic layer 1 and the second elastic layer 3.

The circuit layer 22 may be disposed on the elastic carrier film layer 21 in a partial area near the detection electrode 23, so as to reduce the production cost of the watchband structure while facilitating the electrical connection between the circuit layer 22 and the detection electrode 23.
In addition, when the circuit layer 22 is disposed on the elastic film-carrying layer 21, a planar flat layout is generally adopted to avoid superposition in the thickness direction, so that radio frequency interference between signals collected by each electrode of EMG (electromyogram) can be reduced.
