Conductive hydrogels possessing conductivity, flexibility, and biocompatibility have garnered considerable attention in recent years for their applications in flexible wearable devices. However, most reported conductive hydrogels are mainly elastic hydrogel substrates with chemically cross-linked networks, poor shape adaptability, and irreversible electromechanical properties after molding, thereby limiting their prospective utility in flexible electronics. In this study, we fabricate multifunctional lignin-gelatin-polypyrrole (LGP) hydrogels with plasticity, recyclability, strong adhesion, and biocompatibility via a straightforward methodology employing gelatin, polypyrrole, and sodium lignosulfonate. The resultant LGP hydrogel is interlinked by dynamic noncovalent bonds, yielding remarkable plasticity and recyclability, and could be manipulated by hand to fashion diverse shapes. Additionally, the LGP hydrogel displays substantial adhesion (23.88 kPa to pig skin) and maintains strong adhesion to wide substrates. The LGP hydrogel strain sensor demonstrates high sensitivity (GF = 6.08) and rapid response (107 ms), providing a stable resistive signal output for both large (25−200%) and small (1−5%) strains across diverse operating conditions. Moreover, the LGP hydrogel can be seamlessly integrated as a flexible, wearable strain sensor to facilitate real-time monitoring of human physiological activities.

The fabrication of flexible electronics has gained extensive attention due to the growing demand of flexible devices. Among various methods, laser direct writing technology has emerged as a promising approach due to its advantages of high processing accuracy and simplicity. This research focuses on the preparation of copper microelectrodes using laser‐induced reduction of CuO nanoparticles (Cu NPs) on polyethylene terephthalate films. First, the influence of various parameters on the conductivity of the copper microelectrodes is investigated. Second, flexible copper microelectrodes with a minimum resistivity of 62.29 μΩ cm and an adhesion grade of 4B level are successfully fabricated. Building upon these results, a capacitive pressure sensor is developed with optimal sensitivity of 3.99 Pa−1, good hysteresis of 3.99%, and response and recovery times of 1.2 and 1.3 s, respectively. Repeatability tests confirm the sensor's stability and fatigue resistance. This research provides valuable insights for the production of flexible sensors.
