<p>Liquid-state electronics utilizing functional liquids confined in soft templates as the sensing and actuating component present the ideal platform for enabling conformal coverage of electronic systems on curved and soft surfaces. However, to date, optoelectronic devices based on functional liquid materials as represented by photodetectors and optical memories still have not been proposed; this advancement is crucial to scaling up current liquid-state devices to a system level. Here, this study proposes optoelectronic devices based on liquid metal and photo-switchable ionic liquid with liquid-liquid heterojunction technology. The sensing and memory schemes we present are generic for different liquid-state devices, enabling different functionality to be added to the liquid-state electronics. As a proof of concept, we demonstrate a light sensor composed of the ionic liquid, and an optical memory using a composite of the ionic liquid and polypropylene glycol. These devices are important advancements towards the realization of liquid-state electronic systems.</p>
