Pressure pulse wave sensor

The utility model discloses a pressure pulse wave sensor which comprises a first pressure sensing unit and a second pressure sensing unit. The first pressure sensing unit comprises a first pressure sensing plane, and the second pressure sensing unit comprises a second pressure sensing plane; the first pressure sensing plane and the second pressure sensing plane are located in different planes and cannot be completely overlapped through plane transformation. The two pressure sensing planes perform pressure sensing measurement at the same time, when pressure pulse wave data, measured by the first pressure sensing plane and the second pressure sensing plane, of one pulse period are the same, it means that the pressure pulse wave sensor extrudes the artery blood vessel in place, and the contact face of the artery blood vessel and the first pressure sensing unit is equal to or larger than the first pressure sensing plane; the contact surface of the artery blood vessel and the second pressure sensing unit is equal
