High-Sensitivity Multidirectional Strain Sensor Based on Laser-Induced Graphene for Human Activity Monitoring

This article proposes a high-resolution multidirectional sensor that operates under low strain. Using a laser direct writing method, a porous graphene electrode is prepared on a PI/PDMS composite film, successfully creating a cross-shaped sensitive layer. The sensor exhibits excellent sensing performance, linear response, and repeatability. The unique sensing characteristics of the cross-shaped structure enable the … Read more
