    • An apparatus for harvesting electrical power from hydrodynamic energy, the apparatus including a buoy or other water flotation device connected to an anchor by a tether and a magnetostrictive component having an internal pre-stressed magnetostrictive core that experiences at least a part of load changes experienced by the tether. The magnetic property of the magnetostrictive core is configured to change with changes in stress within the magnetostrictive core along at least one direction within the magnetostrictive component. The hydrodynamic energy acting on the buoy or other water flotation device results in changes in force within the tether, which in turn changes the stress within the magnetostrictive core and consequently changes a magnetic property. The magnetostrictive component is also configured such that the change in the magnetic property will result in a change in magnetic flux, which change can be used to generate electrical power.
    • 一种用于从流体动力能量收集电力的装置,该装置包括通过系绳连接到锚固件的浮标或其它水浮选装置,以及具有内部预应力磁致伸缩芯的磁致伸缩部件,其经受至少部分负载变化 系绳 磁致伸缩芯的磁特性被配置为沿着磁致伸缩部件内的至少一个方向随磁致伸缩芯内的应力变化而变化。 作用在浮标或其他水浮选装置上的流体动力能导致系链内的力的变化,这又改变了磁致伸缩芯内的应力并因此改变了磁性。 磁致伸缩部件也被配置为使得磁特性的变化将导致磁通量的变化,该变化可用于产生电力。
