“…[ 214 ] However, during fabrication, an increase in mass loading leads to higher consumption of binder, which subsequently results in a decrease in electrode conductivity. [ 215 ] An electrode with high mass loading (ultrathick CDI electrode) is required for the high volumetric density. Recently, binder‐free wood‐derived carbon has reported with an excellent salt adsorption capacity(SAC) of 12.45 mg g −1 .…”

Wood‐based flexible and porous architectures are currently receiving extensive attention in the development of flexible devices. The unique water adsorption properties of natural wood enable rapid and spontaneous water uptake, leading to concentration differences that facilitate the diffusion of ions with opposite charges. This article gives a summary of the differences between flexible and porous architectures made from natural wood. It also gives a detailed look at the porous architecture, which is made up of nanochannels, low‐tortuosity channels, and single‐atom sites to improve the electrochemical performance of supercapacitors, metal‐air batteries, lithium‐sulfur batteries, and lithium‐oxide batteries. Moreover, the processing approaches that utilize cell wall engineering to transform flat wood sheets into adaptable 3D structures such as flexible films and foams are described. Finally, some existing challenges and future perspectives faced by wood‐based flexible and spongy architectures for electrochemical energy conversion and storage are described.

The demand for noninvasive wearable sensors for on-site monitoring has surged, particularly in the realm of personalized healthcare. This study introduces a pioneering approach employing a MXene-integrated single-stranded carbon yarn-based sensor patch utilizing a minimalist three-thread electrode setup for real-time monitoring of dopamine levels from artificial human sweat. The ability to immediately sew, weave, or stitch sensor platforms onto any type of clothing makes wearable thread-based sensor patches extremely promising, and it can be positioned in close proximity to the skin. Flexible conductive carbon yarn (CCY) was modified by Ti 3 C 2 T x MXene by a facile dip-coating method which was used as sensing electrodes. Leveraging MXene's high surface area and exceptional conductivity, the sensor's architecture achieved heightened sensitivity and selectivity in dopamine detection and reproducibility in a broad linear range of 1 nM−1 μM with a detection limit of 316 pM, along with real sample tests showing the promise of this platform for real-time physiological monitoring of human performance/fitness under stress as well as diagnostic monitoring through sweat analysis. The three-thread electrode configuration, strategically embedded within the patch, ensures ease of use and comfortable, noninvasive on-body application, offering a promising avenue for continuous, real-time monitoring of dopamine levels in individuals with neurological disorders or relevant medical conditions. This study highlights the potential of MXene-integrated wearable sensor patches with a minimalist electrode setup, advancing the field of wearable sensing technologies for personalized healthcare and point-of-care diagnostics.
