The study on coupling between magnetism and mechanical rotation has a long history [1,2]. The phenomena due to the coupling are caused by the angular momentum conservation between electron spin and mechanical rotation, which has been proved in the general relativistic quantum mechanics . We introduce mechanical effects in spintronics and propose a variety of novel spintronics phenomena . We have observed the generation of spin current by the flow of liquid metals . Combining this effect with the spin Hall effect, the spin-hydrodynamic generation of electricity is obtained . We also show the spin current generation by surface acoustic waves in normal metals . The mechanical generation of spin current opens a door from “Spintronics” to "Spin-Mechatronics".
