Paper is an essential part of our daily life in many different ways. It is made by compressing cellulose fibers sourced from wood into thin sheets. Paper is an inherently flexible material which can transport liquids through its medium by capillary action without the need of external force. The mesh network of cellulose in paper gives it a unique set of mechanical properties. Owing to its exclusive and advantageous properties, paper is being used as an active material and a substrate in electronics. Paper as an active material means that paper is utilized in its intrinsic form without modifications. Activated (or functionalized) paper has been widely exploited in many applications, but in order to take true advantage of all the beneficial properties of paper, it needs to be used in its natural produced form. Notably, paper is employed in humidity sensors, pressure sensors, and MEMS devices in its natural form. Additionally, paper is used as a substrate in additively manufactured and origami-inspired electronic devices. Here, we present an overview of how paper is used to make fully flexible and low-cost devices. Furthermore, the emergence of paper-based point-of-care devices is briefly discussed.

Paper has become one of the most promising substrates for building low‐cost and powerful sensing platforms due to its self‐pumping ability and compatibility with multiple patterning methods. Paper‐based sensors have been greatly developed in the field of environmental monitoring. In this review, we introduced the research and application of paper‐based sensors in environmental monitoring, focusing on the deposition and patterning methods of building paper‐based sensors, and summarized the applications of detecting environmental pollutants, including metal ions, anions, explosives, neurotoxins, volatile organic compounds, and small molecules. In addition, the development prospects and challenges of promoting paper‐based sensors are also discussed. The current review will provide references for the construction of portable paper‐based sensors, and has implications for the field of on‐site real‐time detection of the environment.

“…The PdMoY NS were drop‐cast onto a paper substrate or an interdigitated electrode (IDE) and the H 2 sensing performance of the resulting devices was studied. Although there are a few reports on paper‐based chemiresistive H 2 sensors using 0D Pd nanoparticles, [ 43–45 ] we believe this to be the first study of such a sensor using colloidal 2D Pd alloy nanosheets. Moreover, this is also a first report on inkjet printable H 2 sensors, which we believe could enable mass production of cost‐effective sensitive H 2 sensors for a future hydrogen‐based economy.…”

chemical, [5] gas, humidity, [6] and strain sensing applications. [7,8] Various types of paper-based sensors have been reported, and these can be broadly categorized as optical sensors and electrochemical sensors. Optical sensors include colorimetric, surface-enhanced Raman spectroscopy, and fluorescence sensors, whereas electrochemical sensors include voltammetrybased, potentiometric, and chemiresistive sensors. [9] Chemiresistive sensors are preferred for gas sensing applications due to their low-cost fabrication, portability, and easy-to-read output. [10] In contrast to paper-based chemical sensors and biosensors that are typically disposable, [11] gas sensors, especially chemiresistive sensors, can be used to reversibly detect gases over extended periods of time. Hence, paper-based chemiresistive sensors are promising as ultra-low-cost chemiresistive sensors for gases such as NO 2 , [12] NH 3 , [13] H 2 S, [14] and H 2 . [15] Such paper-based chemiresistive gas sensors often outperform sensors using other (nonporous) substrates such as silicon or polymers, due to synergistic effects of the flexible porous paper coupled with simplicity of fabrication and use. [16] Hydrogen is a highly explosive gas with a lower explosion limit of 4% in air. It also has high diffusivity through many materials due to its small size, creating challenges in safely storing and transporting it. [17] These limitations are a key factor influencing future development of a H 2 -based energy economy. Hence, even with its obvious advantages such as high energy density, compatibility with efficient fuel cells, and carbon-free combustion products, the role of H 2 as a next generation fuel remains uncertain. [18] The cost of H 2 sensors is a significant factor in widespread adoption of H 2 as a fuel, as such sensors will be required at H 2 production units, distribution units, and in H 2 fuel cell-powered vehicles. The US Department of Energy (DOE) has set cost targets for such H 2 sensors, with an ambitious goal of <$15 per sensor for fuel cellpowered vehicles. [19] This goal for low-cost H 2 sensors could be achieved using paper-based Pd chemiresistive H 2 sensors. Pd can selectively absorb a large amount of H 2 at room temperature and form palladium hydride, PdH x , changing both the volume and resistivity of the Pd. [18] Although the material cost of Pd is higher than most conventional metals, low operating cost and selective room-temperature H 2 detection make 2D palladium nanostructures enable sensitive room-temperature detection of H 2 . However, they can be limited by stability and fabrication costs. Stability may be improved by alloying Pd with other metals, while cost could be reduced by using paper as a substrate. An ultra-low-cost sensor using Pd alloy (PdMoY) nanosheets (NS) on paper is reported. The 2D Pd alloy nanosheets are prepared by a solution-phase route, drop cast onto paper (≈1 × 1 cm) with silver contacts drawn on it, and dried. The same material is deposited on an interdigitated electrode (IDE). Both sensors are teste...
