Two-dimensional (2D) materials are highlighted for their exceptional mechanical, electrical, optical, and chemical properties, making them ideal for fabricating high-performance wearable biodevices.

The review categorizes cutting-edge wearable biodevices by their interactions with physical, electrophysiological, and biochemical signals, showcasing how 2D materials enhance these devices' functionality, mainly including self-powering and human-machine interaction.

2D materials enable multifunctional, high-performance biodevices, integrating self-powered systems, treatment platforms, and human-machine interactions, though challenges remain in practical applications.

By anchoring the perovskite sites with the functional groups of CzBP (P = O···Pb, N–H···I and P = O···N–H), the bulk nonradiative recombination is suppressed and ion migration is inhibited. Doping perovskite films with CzBP led to enhanced intercrystallite interactions in the bulk and improved photoluminescence quantum yield.

Using a typical electron-rich moiety as the π-linker to replace the classic alkyl spacer in CzBP facilitated the charge-carrier transport processes and the passivation effect of carbazole further contributed to high V_OC. The optimized 2,7-CzBP-treated device achieves the highest power conversion efficiency (PCE) of 25.88%, with V_OC of 1.189 V for 0.090 cm² and the perovskite solar cell module with a PCE of 21.04% for 14 cm².

For 2,7-CzBP, the more extended conjugation and the more linear molecular geometry result in a more effective improvement in the performance.

This review provides a detailed account of engineered plant cell wall (CW)-mimetic soft materials, which are designed to replicate the intricate composition, structure, and mechanical properties of natural plant CWs.

Experimental methods to create CW-like materials are reviewed, and relevant characterization techniques, including mechanical, chemical, structural, and morphological analyses, are discussed.

 The applications of CW-like materials in several fields, including food packaging, edible films, drug delivery, construction materials, and biocatalysis are highlighted.

Methods for creating the local deformation in two-dimensional transition metal dichalcogenides (2D TMDCs) are introduced.

Modulations of local strain on their optical properties and excitonic behaviors are discussed.

Quantum emitters based on strained 2D TMDCs and other applications are presented.

The design of composite membrane with biomimetic micro-nanostructured superhydrophobic surface and (V_1/2Mo_1/2)₂C MXene photothermal nanomaterials.

The double‐transition‐metal (V_1/2Mo_1/2)₂CT_x MXene exhibits enhanced photothermal conversion performance via the elevated joint densities of states.

The (V_1/2Mo_1/2)₂CT_x MXene-200 composite membrane achieves an evaporation rate of 2.23 kg m⁻² h⁻¹ under one sun, directed salt harvesting, and excellent multifunctionality of anti-/de-icing, anti-fouling, and antibacterial.

Emphasized the innovation in both the material design and methodology between the sensing performance and mechanical properties.

The composite aerogel pressure sensors exhibited low hysteresis (13.69%), wide detection range (6.25 Pa-1200 kPa), and cyclic stability to acquire stable and accurate pronunciation signals.

Over 6888 and 4158 pronunciation signals were collected by the pressure sensor and utilized for training the convolutional neural network model, allowing for accurate recognition of six dialects (96.2% accuracy) and seven words (96.6% accuracy).
