Disclosed is a device (100) for generating electricity from wave motion. The device (100) comprises at least one magnetostrictive element (106) and one or more electrically conductive coils or circuits (not shown) within the vicinity of one or more of the magnetostrictive elements (106). When deployed in a body of water (102), the motion of the body of water (102), including wave motion, causes changes in the strain of the one or more magnetostrictive elements (106). A corresponding change in magnetic field around the one or more magnetostrictive elements (106) generates an electric voltage and/or electric current in the one or more electrically conductive coils or circuits. The device (100) is arranged such that there is substantially no relative movement between the one or more magnetostrictive elements (106) and the one or more electrically conductive coils or circuits. |
