3. The massage chair as claimed in claim 2, wherein: the pulse sensor is a piezoelectric vibration sensor.

4. The massage chair as claimed in claim 3, wherein: the number of the pulse sensors is two, and the pulse sensors are respectively arranged on the seat part and correspond to the positions of the middle positions of thighs of a left leg and a right leg of a human body after the human body sits on the seat.

5. The massage chair as claimed in claim 1, wherein: the massage chair further comprises an electrocardiosignal acquisition device, a controller, a server, a first control device and a second control device, wherein the controller is in data connection with the server and the first control device, the second control device is in data connection with the server, the electrocardiosignal acquisition device acquires electrocardio information in the massage process of a user, converts the electrocardio information into electrocardio data which can be identified by the controller and sends the electrocardio data to the controller, the controller generates control signals and respectively sends the control signals to the first control device and the second control device, and the first control device comprises a switch and is used for controlling the start and stop of the massage chair and the massage control; the second control device comprises a mobile phone and/or a tablet, and electrocardio data transmitted by the server are received and displayed.

6. The massage chair as claimed in claim 5, wherein: the electrocardiosignal acquisition device is connected with an amplifying and filtering device and a signal processing device, the electrocardiosignal is filtered and amplified by the amplifying and filtering device and then is converted into the electrocardio numerical value through the analysis of the signal processing device, and the controller extracts the effective electrocardio numerical value for further processing or outputting.

7. The massage chair as claimed in claim 6, wherein: the controller is composed of at least one single chip microcomputer, and compares effective electrocardiogram data with electrocardiogram characteristic information stored in a server database to identify abnormal characteristic information.

8. The massage chair as claimed in claim 6, wherein: the server comprises a cloud storage, the cloud storage is connected with the controller through the internet of things device, the controller transmits effective electrocardiogram data to the cloud storage for storage, statistics and management, and the controller sends a control command to the cloud storage in the massage process and transmits the effective electrocardiogram data and/or abnormal characteristic information to the second control device.

9. The massage chair as claimed in claim 5, wherein: the electrocardiosignal acquisition device comprises four leg sensors which are respectively arranged on the seat part and close to the artery position of the human body, wherein the thigh part of the left leg and the thigh part of the right leg are formed after the human body is seated.

10. A method for sensing a massage chair with a novel seat sensing device according to any one of claims 5-9, comprising the steps of:

judging a human body: when an object is placed in the seat detection area, the pulse sensor receives a fluctuation signal of the object on the seat, the main control board judges the fluctuation signal, and when the fluctuation signal of the object is within a threshold range, the object is judged to be a human body, and the next round of electrocardio judgment is carried out; if the object fluctuation signal is not within the threshold range, continuing to return to execute the human body judging process;

11. The sensing method according to claim 8, wherein the electrocardiographic range includes a lower threshold value and an upper threshold value of the peak value stored in the memory;

12. The sensing method according to claim 10, wherein when the electrocardiogram judgment result is that abnormal characteristic information is identified, the center board of the massage armchair controls an audio driving board to perform voice broadcasting, and/or the center board of the massage armchair controls a driving board core to stop running.
