Apparatuses and associated methods for converting wave energy into electrical energy are disclosed herein. In some embodiments, a surface-based buoy can be connected to a magnetostrictive element that changes its output voltage when subjected to the in tension. To keep the heave plate under tension, a tether with a heave plate can be attached to the magnetostrictive element.
