Ionic gel-based electronic devices are essential in future healthcare/biomedical applications, such as advanced diagnostics, therapeutics, physiotherapy, etc. However, considerable efforts have been devoted to integrating ultrahigh stretchability, transparency, self-adhesion, and a low-cost manufacturing process in one material for dealing with a variety of application scenarios in the real world. Here, we describe an ionically conductive hydrogel-based electronic technology by introducing charge-rich polyzwitterions into a natural polysaccharide network. The proposed hydrogel possesses ultrahigh stretchability (975%), unique optical transmittance (96.2%), and universal conformal adhesion. The bionic hydrogel electronic devices possess superior dual force/temperature sensation with high sensitivity. Moreover, we develop dedicated sensor arrays via an additive manufacturing route and demonstrate the feasibility of monitoring physical activity or analyzing the mental state of a human body based on the multichannel signal acquisition of joint bending, pulse, vocal-cord vibration, electroencephalogram, eye movement, body temperature, etc. This all-in-one strategy based on a versatile ionic hydrogel electronic platform is anticipated to open up new tactical sensing applications in smart robotics, human–machine interfaces, and wearable monitoring systems.

用于多模式战术传感的超拉伸、高度透明、自粘和 3D 可打印离子水凝胶

基于离子凝胶的电子设备在未来的医疗保健/生物医学应用中至关重要，例如高级诊断、治疗、物理治疗等. 然而，大量的努力致力于将超高拉伸性、透明度、自粘性和低成本制造工艺集成到一种材料中，以应对现实世界中的各种应用场景。在这里，我们通过将富含电荷的多两性离子引入天然多糖网络来描述一种基于离子导电水凝胶的电子技术。所提出的水凝胶具有超高的拉伸性 (975%)、独特的光学透射率 (96.2%) 和通用的保形粘附。仿生水凝胶电子器件具有优异的双力/温感和高灵敏度。而且，等。这种基于多功能离子水凝胶电子平台的一体化策略有望在智能机器人、人机界面和可穿戴监控系统中开辟新的战术传感应用。
