A three-dimensional (3D) wearable electrode set for a human body is provided. The 3D wearable electrode set comprises an integrative first ring electrode and an integrative second ring electrode. The integrative first ring electrode has a conductive layer and a ring basis, and the integrative second ring electrode also has a conductive layer and a ring basis. The conductive layers of the integrative first and second ring electrodes are adopted to cover around the first and second portions of the human body, respectively. The conductive layers are formed with conductive material. The ring bases are formed with insulating fabric.
