Wristband device and system with gesture recognition function and continuous blood pressure monitoring function

A wristband device with a gesture recognition function and a continuous blood pressure monitoring function, comprising:

• a wearable wristband, comprising at least two wristband assemblies, wherein each said wristband assembly comprises an assembly body and at least two contact sensing electrodes inlaid in an inner wall of the assembly body, the at least two contact sensing electrodes inlaid in the same assembly body are arranged vertically, and each said contact sensing electrode is configured to be in an excitation mode or an acquisition mode;
• a PCB, used for realizing switching between a gesture recognition functional mode and a continuous blood pressure monitoring functional mode, applying an excitation current to an excitation current transmitter formed by two electrodes respectively selected from two adjacent said wristband assemblies and acquiring response voltage signals fed back by response voltage receivers formed by electrodes respectively selected from other adjacent said wristband assemblies in the gesture recognition functional mode, modulating the response voltage signals acquired in the gesture recognition functional mode into wrist impedance distribution data, applying the excitation current to an electrode pair on one said wristband assembly in a vicinity of a radial artery and acquiring response voltage signals fed back by electrode pairs on other said wristband assemblies in the continuous blood pressure monitoring functional mode, modulating an optimal response voltage acquired in the continuous blood pressure monitoring functional mode into pulse impedance waveform data of the radial artery in each cardiac cycle, transmitting the wrist impedance distribution data or the pulse impedance waveform data of the radial artery in each cardiac cycle to an upper computer, and receiving a gesture recognition and classification result or a predicted blood pressure fed back by the upper computer, and
• a display screen, used for visualizing a heat rate of a user, the pulse impedance waveform data of the radial artery in each cardiac cycle and the gesture recognition and classification result or the predicted blood pressure received by the PCB.
