NEC与日本东北大学开发出了“自旋热电转换(SpinThermoElectric:STE)元件”。这种元件可通过涂布工艺制作,因此家里的屋顶、汽车和个人电脑等日常生活中所有带有热量的东西,都有可能成为电源。不同于现有的热电转换元件此次NEC等开发的STE元件是将温度梯度转换成电力的热电转换元件的一种。STE元件的特点是采用在基板上层叠膜厚为60～240 nm的超薄磁膜以 NEC and Northeastern University in Japan developed a “spin-thermoelectric conversion (SpinThermoElectric: STE) device.” Such components can be made by a coating process so that everything in your home’s everyday life, like roofs, cars, and personal computers, can become a source of power. Unlike the existing thermoelectric conversion element The STE element developed by NEC et al this time is one type of thermoelectric conversion element that converts a temperature gradient into electric power. The feature of the STE element is the use of an ultra-thin magnetic film having a thickness of 60 to 240 nm laminated on a substrate
