液态电子器件利用限制在软模板中的功能液体作为传感和致动组件，为弯曲和软表面上的电子系统的保形覆盖提供了理想的平台。然而，到目前为止，基于功能液体材料的光电器件，如光电探测器和光存储器，仍然没有提出;这一进步是至关重要的，以扩大目前的液态设备的系统水平。提出了基于液态金属和光开关离子液体的液液异质结技术的光电器件。所提出的感测和存储器方案对于不同的液态设备是通用的，并且使得能够将不同的功能添加到液态电子器件。作为概念的证明，演示了由离子液体组成的光传感器和使用离子液体和聚丙二醇的复合物的光存储器。这些器件是实现液态电子系统的重要进展。
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. Optoelectronic devices based on liquid metal and photo-switchable ionic liquid with liquid-liquid heterojunction technology are proposed. The sensing and memory schemes presented are generic for different liquid-state devices and that enables different functionality to be added to the liquid-state electronics. As a proof of concept, demonstrations are made of 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 toward the realization of liquid-state electronic systems.
