A physiological signal sensing device includes a power supply control circuit, a voltage stabilizing circuit, a control circuit, an isolating circuit, and a signal processing circuit; the power supply control circuit is connected to a power supply; the voltage stabilizing circuit is connected to the power supply control circuit; the control circuit is connected to the voltage stabilizing circuit and the signal processing circuit; and the isolating circuit is connected to the power supply control circuit, the control circuit and the signal processing circuit, and has at least two detection ends. In use, a physiological impedance is connected between the two detection ends; when an impedance value of the physiological impedance is in an impedance range, the power supply control circuit triggers the voltage stabilizing circuit via a trigger path and supplies power to the voltage stabilizing circuit via a power supplying path, and the voltage stabilizing circuit supplies power to the control circuit; and the trigger path is connected to the power supplying path in parallel.
Description
technical field [0001] The present invention relates to a physiological signal sensing device, in particular to a physiological signal sensing device and an operation method for starting and shutting it down. Background technique [0002] Generally, when physiological signal detection devices such as EMG or ECG are in use, it is usually necessary to turn on the physiological signal detection device before attaching a plurality of electrode sheets to the human skin, or first attach the electrode sheets to the human skin, and then Turn on the power switch of the physiological signal detection device. But when not in use, not only the patch needs to be removed from the human skin, but also the switch of the physiological signal detection device needs to be turned off. [0003] At present, whether the electrode pads are attached to the human skin is used as the basis for starting and shutting down, but the physiological signal detection device using this method needs a standby ...
