耐受极端环境水凝胶传感器“编织”成功

Core Insights - The research teams from Fudan University have developed a new strategy for enhancing the performance of hydrogels, inspired by the weaving process of bamboo baskets, which could lead to broader applications in monitoring and human-machine interaction [1][2] Group 1: Research Findings - The proposed strategy involves a stepwise hydrogen bond modulation mechanism that enhances the sensor performance, environmental tolerance, and biocompatibility of hydrogels [1][2] - The hydrogel is composed of polyvinyl alcohol, sodium carboxymethyl cellulose, and gelatin, with each micro-region treated as a "bamboo strip" during the preparation process [2] - The research demonstrated that the hydrogels maintained excellent biocompatibility even after being implanted in biological systems for four weeks [2] Group 2: Application Potential - The enhanced hydrogels are expected to meet the demands of extreme environments, expanding the boundaries of human perception and serving as a "technological shield" for safety [1] - The study's findings have been published in the latest issue of Advanced Functional Materials, indicating a significant contribution to the field of flexible sensors [1]
