“…In fact, photo-responsive, chemical-responsive, and mechanical-responsive patterns have been developed for anticounterfeiting technology. Compared with the current anticounterfeiting technologies, the multiple stimuli responsiveness of our FAC device would show much more advantages in terms of reliability, practicality, identifiability, and convenience of stimulus (see Table 1 and Movie S9 ) 44 .…”

As a primary anticounterfeiting technology, most paper anticounterfeiting devices take advantage of photoresponsive behaviors of certain security materials or structures, thus featuring low-security threshold, which has been a critical global issue. To incorporate optoelectronic devices into existing anticounterfeiting technology suggests a feasible avenue to address this challenge. Here we report a high-performance organic light-emitting paper-based flexible anticounterfeiting (FAC) device with multiple stimuli-responsiveness, including light, electricity, and their combination. Without sacrificing the preexisted security information on the paper, we fabricate FAC device in a facile, low-cost yet high-fidelity fashion by integrating patterned electro-responsive and photo-responsive organic emitters onto paper substrates. By introducing optical microcavities, the FAC device shows considerable color shift upon different viewing angle and applied voltage, which is easily discernible by naked eyes. Notably, the FAC device is bendable, unclonable, and durable (a half-lifetime over 4000 hours at 100 cd m−2).

“…In a recent paper in the literature, a type of flexible X-ray detector based on an active material filled porous nylon membrane presents high sensitivity and flexibility. 10 In contrast, a cellulose fiber paper (CFP), an environmentally friendly material, with high resistance, porous microstructure, a low price, and natural hygroscopicity has recently attracted growing interest as a platform for building flexible electronics, 22,23 such as radio frequency identification (RFID), 24,25 film field-effect transistors, [26][27][28] display devices, 29,30 photovoltaic devices, 31,32 batteries, 33,34 sensors, and photodetectors. 15,[35][36][37][38] The porous microstructure, interlacing fibers, and high surface roughness of the cellulose fiber provide high adhesion, allowing various materials to be coated on it.…”

“…Being flexible, eco-friendly, low cost, and easy to fabricate, the paper has gained significant interest as a substrate in various electronic devices such as thin-film transistors, sensors, photodiodes, and so forth. − The micro-channels of paper have an attractive characteristic that the fluid can flow within a microfluidic device using the capillary action without any external pumping, making it suitable for various applications. , Here, we have used two-legged paper-based microfluidic channels to conduct water from the reservoir to the evaporator surface in a cone-shaped 3D solar steam generator (SSG) made of an aluminum sheet coated with a selective solar absorber (SSA) on the inner side and a hydrophilic polyvinylidene fluoride (PVDF) membrane filter wrapped on the outer side. Furthermore, we have generated electricity throughout the day by running wastewater of different ionic concentrations through two legs.…”

Synergistic generation of freshwater and electricity using solar light would be an ideal solution for global freshwater challenges and energy demands. Recently, interface solar steam generation has been considered one of the promising cost-effective alternatives for freshwater generation. Here, we have systematically maintained the salinity gradient within two-legged paper-based microfluidic channels to transport wastewater from the reservoir to the evaporator surface and generate electricity all-day-long. Flowing seawater (3.5 wt % NaCl) on one leg and tap water on the other of the water-conducting channels connected to a conical evaporator, we achieved an average open-circuit voltage (V OC) of 150 mV and a short-circuit current of 6.5 μA across each channel along with a water evaporation efficiency of 88%. As the V OC depends only on the ion concentration gradient within the channel in the direction perpendicular to the water flow, the electricity generation persists throughout the day and can be tuned by varying the salinity. Increasing the salt concentration of the seawater to 20 wt %, the V OC increased to 250 mV in a single channel. In an evaporator connected with four such channels, we achieved a maximum output power density of 9.9 mW m–2 in a series combination without sacrificing the evaporation rate. Furthermore, removing agglomerated salt from the evaporator surface, we harvested salt at a rate of 0.33 kg m–2 h–1. Therefore, our approach provides an alternative way of freshwater generation, salt harvesting, and all-day-long electricity production simultaneously.
