An ear-worn eddy current measurement device includes a sensor and a control module. The sensor includes a coil and a setting structure combined with the coil. The setting structure is configured to arrange the coil on an ear of a subject and place an emission surface of the coil towards an ear measurement area of the subject. The control module is coupled to the coil, and is configured to drive the coil to perform eddy current induction measurement on the measurement area and obtain at least one physiological information of the subject. |
