A double network structure with metal ions was created to enhance the mechanical stability of hydrogels and increase their low conductivity. For this purpose, P(AM_AcOr_Gelatin) hydrogel synthesized by combining gelatin, a biocompatible polymer, N-δ-acryloyl-ornithine (AcOr), an amino acid derivative, acrylamide (AM). Because acid-based monomer added charged groups network, exhibited improved conductivity motion sensitivity properties compared polyacrylamide (PAM) hydrogels. Furthermore, we altered introducing Fe3+ Cu2+ ions, resulting in formation P(AM_AcOr_Gelatin)-Fe3+ P(AM_AcOr_Gelatin)-Cu2+ The containing had coordination bonds between AcOr. Additionally, there were other noncovalent present, further increased (approximately 95% improvement) stretchability (more than double). resistance changed, depending on bending position strain applied layer. results demonstrated that layer good sensitivity, enhanced gauge factor (GF) approximately 1.7 (at 250% strain) ranging from 3355 4387 μS·cm–1.

Hydrogel-based sensors have been widely studied for perceiving the environment. However, simplest type of resistive still lacks sensitivity to localized strain and other extractable data. Enhancing their expanding functionality perceive multiple stimuli simultaneously are highly beneficial yet require optimal material design proper testing methods. Herein, we report a elastic, sponge-like hydrogel its derived multimodal iontronic sensor. By unidirectional freeze casting poly(vinyl alcohol) (PVA) with electrospun cellulose nanofibers (CNF), hierarchical structure aligned PVA channels supported by interlaced CNF tangles is created. The ensures both efficient mass transport good elasticity, enhancing reversible compressibility ionic conductivity. Combining this sponge impedance-based measurement methods allows development capable detecting local strain, position, object-in-contact. Integrating these sensing capabilities, two-dimensional small motion monitor, 3D input interface, identification gripper demonstrated. This study provides simple approach versatile sensors.

The development of wearable electronic devices requires stretchable, highly conductive, self-recovery, and ideally environmentally resistant sensors. Hydrogels are ideal candidates for fabricating flexible sensors due to their stretchability unique ionic conduction pathways. However, the intrinsic incompatibility conductive elastic networks in hydrogels high hydrophilicity hydrogel network led difficulties obtaining with strong mechanical properties, conductivity, rapid self-recovery ability, antiswelling properties. Based on single-core multidentate coordination strategy, coordinated chitosan/poly(acrylic acid)/Al3+ (CPAL) were prepared Al3+ as a metal center amino group chitosan (CS) carboxyl poly(acrylic acid) (PAA) atoms. obtained exhibit excellent tensile stress/strain: 1.11 ± 0.04 MPa/2472.79 99.27%, capability (mechanical properties fully recovered 10 min), antifatigue property, good conductivity (1.09 0.02 S/m), property. Furthermore, based CPAL demonstrated multiplex mode sensing. It was worth noting that could not only use Morse code table realize mechanical-information visualization but also detect human condition multiple dimensions, including temperature, electromyographic (EMG), electrocardiogram (ECG). In this work, we reported strategy provided pathway hydrogel-based sensors, showing great potential devices.
