A four-diode full-wave ionic current rectifier based on bipolar membranes: overcoming the limit of electrode capacity

Adv Mater. 2014 Aug 13;26(30):5143-7. doi: 10.1002/adma.201401258. Epub 2014 May 26.


Full-wave rectification of ionic currents is obtained by constructing the typical four-diode bridge out of ion conducting bipolar membranes. Together with conjugated polymer electrodes addressed with alternating current, the bridge allows for generation of a controlled ionic direct current for extended periods of time without the production of toxic species or gas typically arising from electrode side-reactions.

Keywords: bioelectronics; bipolar membranes; conjugated polymer electrodes; ion transport; ionics.
