Abstract: A physiological signal measurement device is disclosed. In some implementations, the physiological signal measurement device includes a fixing element, a rack, a first sensor, and a second sensor. The fixing element is configured to be fixed on a limb of a user. The rack is configured to engage the fixing element and includes a first end and a second end distal to the first end. The first sensor is disposed on the first end of the rack. The sensor is disposed on the second end of the rack. The first end of the rack has a first stiffness, the second end of the rack has a second stiffness, and the first stiffness is higher than the second stiffness.
