We propose a straightforward access to a rotating light‐emitting device powered by wireless electrochemistry. A magnetic stirrer is used to rotate a light‐emitting diode (LED) due to the intrinsic magnetic properties of the tips that contain iron. At the same time, the LED is submitted to an electric field and acts as a bipolar electrode. The electrochemical processes that are coupled on both extremities of the LED drive an electron flow across the device, resulting in light emission. The variation of the LED alignment in time enables an alternating light emission that is directly controlled by the rotation rate. The stirring also enables a continuous mixing of the electrolyte that improves the stability of the output signal. Finally, the LED brightness can readily reveal a change of chemical composition in the electrolyte solution.

基于磁力搅拌和无线电化学的发光装置的远程致动。

我们提议直接访问由无线电化学技术驱动的旋转发光设备。由于含铁尖端的固有磁性，磁力搅拌器可用于旋转发光二极管（LED）。同时，LED受到电场作用并充当双极电极。耦合在LED两端的电化学过程驱动电子流过设备，导致发光。LED排列时间的变化使得交替发光可以直接由转速控制。搅拌还能够使电解质连续混合，从而改善了输出信号的稳定性。最后，LED亮度可以很容易地揭示电解质溶液中化学成分的变化。
