Abstract
The invention discloses an electric power generating device applied on a wearable object. The electric power generating device comprises a transmission unit, a magnetic permeable member, a magnetic member, a core, and a coil. The transmission unit transfers an external force received by the wearable object to a driving force. The core is configured in the wearable object and has a first end. The coil is coupled to the core. The magnetic permeable member is configured in the wearable object to receive the driving force and move by the driving force. The magnetic member is configured on the magnetic permeable member and near the first end. When the magnetic permeable member pushes the magnetic member to move relatively to the first end through the driving force, the magnetic flux in the core varies to lead the coil to induce an induced electromotive force.
