“…In contrast to the printing technique, neither conductive inks nor external precursors are needed during the device fabrication in LDW, since cardboard is made from cellulose bers, 32 which provides the carbon sources for various type of sensors. 33,34 LDW of carbonaceous sensors, including pressure, temperature, and humidity sensors was investigated. LDW-pressure sensor arrays have a layered porous structure.…”

electronics that withstand mechanical stress. Successful applications of such devices are spread in areas of health, environment, and energy. [1-3] For instance, electronic skin, [4] human-robot interfaces, [5] stretchable electrodes, [6] supercapacitors, [7] transistors, [8] and electrochemical wearable devices [9] have been extensively studied in this direction. In particular, electrochemical devices often permeate into different areas bringing a plethora of high-performance applications. Most of the fabrication methods used to fabricate stretchable electrochemical devices consist of combining elastomers, such as polydimethylsiloxane (PDMS), Ecoflex, Silbione, or polyurethane, with conductive structures. The reported methods are divided into two main routes: i) mixing the elastomer with conductive structures in a single step [6] or ii) preparing the elastomeric substrate in a first step followed by transfer [9-13] or printing [14-17] the conductive materials in a second step. Among the different conductive materials (conductive polymers, Au, and Ag), carbonbased materials are well-known due to their high sensitivity, stability, remarkable electrical properties, and the possibility of functionalization by several routes. [10,11,14-16] Carbon nanotubes and graphene have shown interesting properties for several applications in the field of flexible and stretchable devices. Their high aspect-ratio plays an important role in maintaining their electrochemical performance under mechanical stress (bend, twist, crumple, stretch). [2] However, their high preparation cost, low production yields, and the sophisticated equipment needed for their synthesis, in addition to their environmentally harmful preparation processes, are some drawbacks that need to be circumvented. Therefore, there is an increasing interest in preparing conductive carbon-based materials from low-cost, abundant, and sustainable sources. Due to the environmentally friendly characteristic and large-scale production, raw materials as biopolymers and some synthetic polymers have been used in the process of carbonization, such as natural and synthetic silk, [18-21] sponges, [22] and various types of cellulose-based substrates Pyrolyzed cellulose-based materials are extensively used in many fields for many different applications due to their excellent electrical properties. However, pyrolyzed materials are extremely fragile and prone to crack. To address this issue, a new fabrication method is reported to delay the capillary flow of elastomeric materials into the porous structure of the paper. By changing the surface chemistry and porosity of the material, the capillary flow of the elastomer through the porous structure is delayed. Delayed capillary flow of elastomers (DCFE method) ensures both extremely high mechanical stability and electrochemical performance to the devices. Impressively, the electrochemical devices can be bent, folded, twisted, and stretched at 75% of their original length without hindering their electrochemical response. Moreover, cooper...
