Flexible noncontact sensors are of great significance in contemporary applications. Nevertheless, conventional that rely on metal electrodes have limited flexibility, and their multilayer architectures likely to experience interfacial delamination during extended use. To tackle these problems, we introduce an all-gel-based flexible triboelectric sensor, which consists two parts, i.e., the gelatin/poly(vinyl alcohol) (PVA)/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS)/graphene (G) electrode hydrogel PVA/cellulose/carbon nanotubes (CNT) aerogel. The not only features outstanding biocompatibility but also exhibits high conductivity. aerogel demonstrates excellent mechanical properties, such as good elasticity durability. This sensor can stably output a current 1.18 μA, charge 18.4 nC/cm2, voltage 3.7 V at stable state. It accurately reliably detect wide range human motions, elbow bending, knee movement, running, providing reliable approach for motion perception facilitating progress relevant fields.

Abstract Wound healing is a dynamic and overlapping bio‐process with varied cellular molecular characteristics involved. Traditional wound dressings have made significant achievements in accelerating healing; however, they lack the ability to monitor changes of wounds, which limits effectiveness management. Currently, development flexible electronics‐based intelligent that can real‐time manner make positive impact on clinical practice. MXenes, also known as type 2D inorganic compound, are generally considered ideal precursors for fabricating electronics. MXenes‐based electronics not only biomarkers wounds (e.g., temperature, pH, lactic acid) but promote by combining other bio‐activities. This review begins brief introduction challenges associated early diagnosis wounds. It then provides comprehensive summary discussion fabrication applications monitoring treatment. Finally, it explores current future directions this cutting‐edge field.
