Researchers at the Virginia Commonwleth University have come up with . . . a circuit that requires such little power all it needs is the ambient energy in an environment to run. In other words, it can run without need of a power lead or battery, relying instead on some energy constant in the environment in which it functions e.g. the human body. In order to create something that can run on such low, ambient energy, you need to use electronics that require next to no power to function. So instead of the typical charge-based electronic switches used today, the researchers turned to spin transport electronics, more commonly known as spintronics.

维吉尼亚大学的调查者们开发出了一种电路，它需要的电能如此之少，以至于来自环境中的微弱能量即可使它运行。换句话说，它的运行可以不需要电源线或电能，仅仅依赖周围环境中恒有的些许能量，如人体体温。为了使电路能运行在如此低的环境能（ambient energy）之下，你需要设计几乎不消耗电能的电子。因此，取代日常使用的传统的基于电荷的电子开关，调查者们转向使用旋转传输电子，即通常所说的“自旋电子”。
