摘要

In the past two decades, organic electronic materials have enabled and accelerateda large and diverse set of technologies, from energy-harvesting devicesand electromechanical actuators, to flexible and printed (opto)electroniccircuitry. Among organic (semi)conductors, organic mixed ion-electronicconductors (OMIECs) are now at the center of renewed interest in organicelectronics, as they are key drivers of recent developments in the fields of bioelectronics,energy storage, and neuromorphic computing. However, due tothe relatively slow switching dynamics of organic electronics, their applicationin microwave technology, until recently, has been overlooked. Nonetheless,other unique properties of OMIECs, such as their substantial electrochemicaltunability, charge-modulation range, and processability, make this field of useripe with opportunities. In this work, the use of a series of solution-processedintrinsic OMIECs is demonstrated to actively tune the properties of metamaterial-inspired microwave devices, including an untethered bioelectrochemicalsensing platform that requires no external power, and a tunable resonatingstructure with independent amplitude- and frequency-modulation. Thesedevices showcase the considerable potential of OMIEC-based metadevices inautonomous bioelectronics and reconfigurable microwave optics.
