The Cover Feature shows a freestanding light‐emitting diode (LED) that is addressed in a wireless manner by means of bipolar electrochemistry. Also, the tips of this electronic device are made out of iron enabling thus a magnetic stirring. The brightness of the LED can be readily used as an optical readout to monitor a chemical composition change in the electrolyte solution in real time. More information can be found in the Article by A. L. Dauphin et al.

封面功能：基于电磁搅拌和无线电化学的发光装置的远程致动（ChemPhysChem 7/2020）

封面功能显示了一个独立的发光二极管（LED），可通过双极电化学方法以无线方式对其进行寻址。而且，该电子设备的尖端由铁制成，因此能够进行磁力搅拌。LED的亮度很容易用作光学读数，以实时监控电解质溶液中的化学成分变化。可以在A. L. Dauphin等人的文章中找到更多信息。
