Wearable real-time electrical signal acquisition device

The invention relates to a wearable real-time electrical signal acquisition device. The wearable real-time electrical signal acquisition device is characterized by comprising a wearable vest, and a plurality of bandages are horizontally arranged on the inner side of the vest at intervals; an embedded controller is fixed on any one of the bandages, a micro-motor used for adjusting tightness of the bandages is arranged at the joint of the bandages, more than one electrocardiograph collection electrode is movably arranged on the bandages, buzzers are fixedly arranged on the bandages, pressure sensors are arranged on the electrocardiograph collection electrodes, and the micro-motor, the pressure sensors and the buzzers are connected with the embedded controller through leads; contact pressure between the electrocardiograph collection electrodes and skin of a subject is detected through the pressure sensors transmitting detected pressure signals to the embedded controller, and the embedded controller controls the micro-motor to adjust tightness of the bandages; when contact problems arise between the electrocardiograph collection electrodes and the skin of the subject, the buzzers alarm to prompt the subject to have the corresponding electrocardiograph collection electrodes examined. The wearable real-time electrical signal acquisition device can be widely applied to acquisition of human electrocardiograph signals.
