All-Gel-Based Triboelectric Noncontact Sensor for Human Motion Perception

ACS Applied Materials & Interfaces, Год журнала: 2025, Номер unknown

Опубликована: Апрель 1, 2025

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.
