Abstract Electrode interfaces functionalized with various signal‐responsive materials have been designed to allow switchable properties of the modified electrodes. External signals of different nature (electrical potential, magnetic field, light, chemical/biochemical inputs) were applied to reversibly activate–deactivate the electrode interfaces upon demand. Multifunctional properties of the modified interfaces have allowed their responses to complex combinations of external signals. Further increase of their complexity has been achieved by integrating the signal‐responsive interfaces with unconventional biomolecular computing systems logically processing multiple biochemical signals. This approach has resulted in electrochemical systems controlled by complex variations of biomarkers corresponding to different physiological conditions, thus allowing biological control over electronic systems. The switchable electrodes have been integrated with various “smart” biosensing and signal‐processing systems and have been used to assemble biofuel cells producing power on demand.
