Article Abstract
To date, flexible pressure sensors built on silver nanowires (AgNWs) have attracted tremendous attention, owing to their versatile applications in wearable, human-interactive, health-monitoring devices. Cellulose and its derivatives, which show great promise in serving flexible pressure sensors as the desired substrate due to their natural abundance, biocompatibility, easy processibility, and low costs. Herein, we reported a rational strategy to design a silver nanowires-dual-cellulose conductive paper. Its morphology, chemical and crystal structures, thermal stability, mechanical performances, and electrical properties were carefully studied. The results suggested that good tensile properties (tensile strength ≤8.10 MPa), high electrical conductivity (≤ 1.74 × 10 S·m) with long-term stability, and good adhesion stability (bending cycles over 500) were obtained. Furthermore, the use of such conductive paper as substrate for versatile flexible pressure sensors was demonstrated, which exhibited fast response (~ 0.48 s) and high sensitivity, in response to finger motion, voice recognition, and human pulse, etc.

Objectives: Cervical cancer is a serious threat to women's life and health and has a high mortality rate. Colposcopy is an important method for early clinical cervical cancer screening, but the traditional vaginal dilator has problems such as discomfort in use and cumbersome operation. For this reason, this study aims to design an intelligent vaginal dilatation system to automate colposcopy and enhance patient comfort.

Wearable sensors integrated with deep learning techniques have the potential to revolutionize seamless human-machine interfaces for real-time health monitoring, clinical diagnosis, and robotic applications. Nevertheless, it remains a critical challenge to simultaneously achieve desirable mechanical and electrical performance along with biocompatibility, adhesion, self-healing, and environmental robustness with excellent sensing metrics. Herein, we report a multifunctional, anti-freezing, self-adhesive, and self-healable organogel pressure sensor composed of cobalt nanoparticle encapsulated nitrogen-doped carbon nanotubes (CoN CNT) embedded in a polyvinyl alcohol-gelatin (PVA/GLE) matrix.

The high sensitivity and wide linearity are crucial for flexible tactile sensors in adapting to diverse application scenarios with high accuracy and reliability. However, conventional optimization strategies of constructing microstructures suffer from the mutual restriction between the high sensitivity and wide linearity. Herein, a novel design of localized gradient conductivity (LGC) with partly covered low-conductivity (low-σ) carbon/Polydimethylsiloxane layer on high-conductivity (high-σ) silver nanowires film upon the micro-dome structure is proposed.

Purpose Of Review: This opinion article from the EAU Endourology Section critically summarizes the existing evidence on flexible and navigable suction ureteral access sheaths (FANS) to determine if they represent a paradigm shift in managing kidney and ureteral stones with flexible ureteroscopy (FURS). This scoping review aims to synthesize recent findings on FANS efficacy, safety, and potential to overcome limitations of conventional ureteral access sheath (C-UAS) and other modalities.
Recent Findings: Current evidence demonstrates FANS significantly outperforms C-UAS.

Background: Chronic nonspecific low back pain (CNSLBP) is associated with thoracolumbar fascia (TLF) dysfunction. However, the structural effects of Gua Sha, a Traditional Chinese Medicine technique, remain unclear. This study aimed to explore the acute and short-term effects of Gua Sha therapy on TLF thickness, pain intensity, and related physiological parameters in patients with CNSLBP.
