Hydrogels that possess both self-healing capabilities in tissue engineering and mechanical properties play a pivotal role in advancing flexible sensing and wearable bioelectronic devices technologies. The primary challenge in practical applications revolves around the delicate equilibrium between mechanical properties and self-regeneration capabilities. Herein, the utilization of conjugated carbonyl compound PI-COF (Polyimide-Covalent organic framework) is proposed as reinforcing phases to interact with iron ions, thereby preparing PAA-based double network hydrogel with high cross-linking density. Through comprehensive component analysis, it has been determined that the existence of metal coordination bonds, hydrogen bonds along with π–π conjugate system imparts (PAA-2DC)-Fe3+/PEDOT: PSS hydrogel excellent self-healing performance (3rd, 196.2%), elongation (1312%) and tensile strength (71 kPa). Additionally, the hydrogel exhibits remarkable conductivity (σ = 0.5 S m−1), strain sensing sensitivity (GF = 9.3), self-adhesive properties and demonstrating its ability to differentiate between materials of various sizes and possesses antibacterial properties. These exceptional attributes highlight the potential of the hydrogel in tissue engineering and flexible sensing, simultaneously providing novel research ideas and theoretical basis.

用于触觉识别的共轭羰基化合物增强水凝胶
兼具组织工程自愈能力和机械性能的水凝胶在推进柔性传感和可穿戴生物电子设备技术方面发挥着关键作用。实际应用中的主要挑战围绕机械性能和自我再生能力之间的微妙平衡。在此，提出利用共轭羰基化合物PI-COF（聚酰亚胺共价有机骨架）作为增强相与铁离子相互作用，从而制备具有高交联密度的PAA基双网络水凝胶。通过综合成分分析，确定金属配位键、氢键以及π-π共轭体系的存在赋予(PAA-2DC)-Fe 3+ /PEDOT: PSS水凝胶优异的自修复性能(3rd, 196.2) %)、伸长率 (1312%) 和拉伸强度 (71 kPa)。此外，该水凝胶还表现出显着的导电性（σ = 0.5 S m -1 ）、应变传感灵敏度（GF = 9.3）、自粘性能，并证明其能够区分不同尺寸的材料并具有抗菌性能。这些特殊的属性凸显了水凝胶在组织工程和柔性传感方面的潜力，同时提供了新颖的研究思路和理论基础。
