In recent years, flexible pressure sensors have played an increasingly important role in human health monitoring. Inspired by traditional papermaking techniques, we developed a highly flexible, low-cost, and ecofriendly sensor using shredded paper fibers as the substrate. By combining properties of laser-induced graphene with structure fibers, improved internal pressure-sensitive designed conical surface microstructure, providing new insights into nanomaterial engineering. It features low resistance (424.44 Ω), energy consumption only 0.367 μW under 1.96 kPa, high sensitivity (1.68 kPa-1), wide monitoring range (98 Pa-111.720 kPa). The microstructure (MFTG) this study has total thickness comparable to A4 paper, is soft bendable, can be cut any shape like fit body, holds great potential for continuous activity status physiological information.

Conductive organohydrogels-based flexible pressure sensors have gained considerable attention in health monitoring, artificial skin, and human-computer interaction due to their excellent biocompatibility, wearability, versatility. However, hydrogels' unsatisfactory mechanical unstable electrical properties hinder comprehensive application. Herein, an elastic, fatigue-resistant, antifreezing poly(vinyl alcohol) (PVA)/lipoic acid (LA) organohydrogel with a double-network structure reversible cross-linking interactions has been designed, MXene as conductive filler is functionalized into further enhance the diverse sensing performance of sensors. The as-fabricated MXene-based PVA/LA organohydrogels (PLBM) exhibit stable fatigue resistance for over 450 cycles under 40% compressive strain, elasticity, (<−20 °C), degradability. Furthermore, based on PLBM show fast response time (62 ms), high sensitivity (S = 0.0402 kPa–1), stability (over 1000 cycles). exceptional enables monitor human movements, such joint flexion throat swallowing. Moreover, integrating one-dimensional convolutional neural networks long–short-term memory deep learning algorithms developed recognize letters 93.75% accuracy, representing enormous potential monitoring motion interaction.
