Title:
SIGNAL MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/055212
Kind Code:
A1
Abstract:
A signal measurement device (100), comprising: an electrode (110), the electrode (110) being attached to a human body and used for acquiring an electromyographic signal of the human body within a target frequency range; an alternating current excitation source (120) electrically connected to the electrode (110) and used for providing an excitation signal of a first frequency so as to generate a detection signal reflecting the contact impedance between the electrode (110) and the human body; and a gain circuit (130) used for providing a gain for the electromyographic signal and the detection signal. According to the signal measurement device (100), by means of providing the gain circuit (130), the gain is provided for the acquired electromyographic signal and detection signal, thereby improving the strength and quality of the electromyographic signal and the detection signal, and enabling the signal measurement device (100) to accurately perform monitoring.
