Abstract
A physiology signal sensing device includes an elastic pad and a strain sensor element. The elastic pad is used for contact with a human body, and corresponds a blood vessel of the human body. The strain sensor element is disposed in the elastic pad and includes a conductive element. The conductive element deforms according to the vibration of the blood vessel, and the resistance value of the conductive element varies according to the strain of the conductive element.
