Challenges that impede the broad utilization of natural polymers in soft electronics, including limited durability, compromises between conductivity and deformability, and limited exploration in controllable degradation, etc. Here, the natural‐polymer polymorphs and their compatibilization with a variety of inorganic/organic conductors through interfacial bonding/intermixing and surface functionalization for applications in various device modalities are delineated. In the research field of soft electronics, regenerated natural polymers are promising building blocks for passive dielectric substrates, active dielectric layers, and matrices in soft conductors. Natural polymers, which can degrade in nature, provide opportunities to replace petroleum‐based polymers, meanwhile driving technological advances and sustainable practices. Pollution caused by nondegradable plastics has been a serious threat to environmental sustainability. Our work demonstrates that the sustainable, flexible, and transparent FG films are a promising alternative for green and degradable substrates in the field of flexible electronics, including foldable displays, wearable devices, and health monitoring. The device could be dissolved in water within 3 min. The fabricated ACEL device based on the Ag NWs-FG film exhibited high flexibility and luminance up to 56.0 cd m-2. After forming a composite with silver nanowires (Ag NWs), the Ag NWs-FG film showed a transmittance up to 82.3% and a sheet resistance down to 22.4 Ω sq-1. The transmittance of these FG films was up to 91.1% in the visible spectrum, comparable to that of polyethylene terephthalate (PET) (90.4%). ![]() These films could dissolve in water within seconds at 60 ☌ and degrade completely within 24 days in soil. The FG films were made from fish scales, which are sustainable, cost-efficient, and eco-friendly. Herein, we have developed a flexible transient ACEL device based on transparent fish gelatin (FG) films. Transparent plastics are usually used as substrates in ACEL devices however, they are undegradable and may cause serious environmental pollution. “We stopped to marvel at Macropinna microstoma before it swam away,” the researchers said.In the past decades, various alternating current electroluminescent (ACEL) devices, especially the flexible ones, have been developed and used in flat panel display, large-scale decorating, logo display lighting, optical signaling, etc. Tommy Knowles and his team from the Monterey Bay Aquarium were aboard MBARI’s R/V Rachel Carson with ROV Ventana to collect jellies and comb jellies for the Aquarium’s upcoming Into the Deep exhibition when they spotted this fascinating fish. Macropinna microstoma normally hangs nearly motionless in the water using its large fins for stability.ĭr. “In 2019, our researchers learned the barreleye can rotate its eyes beneath that dome of transparent tissue.” “But how does this fish eat when its eyes point upward and its mouth points forward?” ![]() “Its eyes look upwards to spot its favorite prey - usually small crustaceans trapped in the tentacles of siphonophores - from the shadows they cast in the faint shimmer of sunlight from above.” “The barreleye lives in the ocean’s twilight zone, at depths of 600 to 800 m (2,000 to 2,600 feet),” MBARI scientists said. This protects its sensitive eyes from the nematocysts (stinging cells) of the siphonophores, one of the apparent sources of its food. It also has a highly unusual transparent, fluid-filled shield on its head. It has a tiny mouth, most of its body is covered with large scales, and its eyes are capped with bright green lenses. Macropinna microstoma measures around 15 cm (6 inches) in length. It occurs at lower mesopelagic depths beneath temperate and subarctic waters of the North Pacific from the Bering Sea to Japan and Baja California, Mexico. The species was discovered and described in 1939 by the U.S. Macropinna microstoma is a deep-sea ray-finned fish in the barreleye family Opisthoproctidae.
