Description

Technical Field

[0001] This invention belongs to the technical field of bioelectric signal detection, and specifically relates to a flexible circuit board electromyography (EMG) wristband. Background Technology

[0002] An electromyography (EMG) wristband is a wearable device based on bioelectrical signal (EMG) detection technology. EMG signals are electrical activities generated when the nervous system sends commands during muscle contraction and relaxation. These signals are detected on the skin surface via electrode sensors. By collecting and analyzing these signals, the EMG wristband can reflect the user's muscle activity state, which can then be used in applications such as gesture recognition, controlling electronic devices, motion monitoring, and rehabilitation training.

[0003] Traditional electromyography (EMG) signal detection devices are typically large and complex, commonly found in medical settings for disease diagnosis and rehabilitation. With advancements in electronic technology, sensor technology, microprocessors, and wireless communication technology, EMG signal detection devices are increasingly moving towards miniaturization, portability, and low power consumption. EMG wristbands, as innovative wearable devices, offer convenient everyday use, overcoming the limitations of traditional devices.

[0004] Existing electromyography (EMG) wristbands use a wristband structure with attached electrode pads that fit snugly against the body to collect bioelectrical signals. During assembly, the electrode pads for collecting EMG signals and the flexible circuitry for transmitting signals are typically encapsulated together in rubber before being manufactured into a wristband worn on the body. This traditional design is prone to causing the wires to break during bending, coiling, and folding of the EMG wristband, and it also has poor heat dissipation, which can easily lead to localized overheating. Summary of the Invention

[0005] To address the aforementioned issues, this invention proposes a flexible circuit board electromyography (EMG) bracelet. The design concept involves connecting the built-in electrode plates of the bracelet in series with a flexible circuit board as a whole, replacing the wire connections inside conventional EMG bracelets, thus avoiding the risk of wire breakage, while improving the heat dissipation and solderability of the circuit.

[0006] A flexible circuit board electromyography (EMG) bracelet includes a flexible circuit board 8, with the extension direction of the flexible circuit board 8 defined as left-right. A first electrode plate 81, a second electrode plate 82, a third electrode plate 83, and a fourth electrode plate 84 are sequentially arranged on the flexible circuit board 8 from left to right. The bottom of the first electrode plate 81, the second electrode plate 82, the third electrode plate 83, and the fourth electrode plate 84 are all provided with protruding electrode pieces 6, which can receive human EMG signals. The surface of the flexible circuit board 8 connected to the second electrode plate 82 is covered with a plastic upper shell 2, and the flexible circuit board 8 is connected to a large circuit board 7 built into the plastic upper shell 2 through a flexible circuit board interface 9. The large circuit board 7 carries a battery 10.

[0007] The flexible circuit board 8, the first electrode plate 81, the third electrode plate 83 and the fourth electrode plate 84 outside the plastic upper shell 2 are covered with a rubber-coated module 1; the electrode sheet 6 is exposed outside the rubber-coated module 1; the left end of the rubber-coated module 1 outside the first electrode plate 81 is provided with a fixing buckle 4, and the right end of the rubber-coated module 1 outside the fourth electrode plate 84 is provided with an integral fixing buckle 5.

[0008] More specifically, the plastic upper shell 2 is equipped with a magnetic female connector 3 that can be connected to an external power source.

[0009] The beneficial effects of this invention are as follows: replacing the wire connections inside a conventional myoelectric bracelet with a flexible circuit board avoids the risk of the internal circuit breaking due to bending, winding, and folding of the myoelectric bracelet, while improving the heat dissipation and solderability of the circuit.
