It is placed on the front surface of the phone case to allow the index finger or middle finger that is used to the right hand to touch the ECG right hand electrode. It is worth noting that the PPG sensor, ground/right foot drive electrode, ECG right-hand electrode and ECG left-hand electrode can be adjacent to the long side of the phone case to conform to the holding habit of the straight-hand phone; and, PPG sensor, ground /The right foot drive electrode, the ECG right hand electrode and the ECG left hand electrode can also be adjacent to the short side of the mobile phone case to conform to the holding habit of the horizontal operation of the mobile phone.

When the carrier is a steering wheel, the PPG sensor, the ground/right foot driving electrode, the ECG right-hand electrode and the ECG left-hand electrode can be disposed on the same side of the steering wheel facing the user, wherein the ECG right-hand electrode and the PPG sensor and the ground/right foot driving electrode One of them can be located on the right side of the steering wheel, and the ECG left hand electrode and the other of the PPG sensor and the ground/right foot drive electrode can be located on the left side of the steering wheel to match the finger. Master the gripping habits of the entire steering wheel; alternatively, one of the ECG right-hand electrodes and one of the PPG sensor and the ground/right-hand drive electrode can be located on opposite sides of the right side of the steering wheel, while the ECG left-hand electrode and PPG sensor are grounded/right The other of the foot drive electrodes can be respectively located on opposite sides of the left side of the steering wheel to conform to the holding habits of the plurality of fingers respectively contacting the opposite sides of the steering wheel.

In conclusion, the present invention has been disclosed in the above preferred embodiments, and is not intended to limit the present invention. A person skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention.
