Efficient detection of aqueous copper ions is of high significance for environmental and human health, since copper is involved in potent redox activity in physiological and pathological processes. Covalent organic frameworks (COFs) have shown advantages in efficient capturing and detecting of copper ions due to their large surface area, robust chemical stability, and high sensitivity, but most of...
High‐Resolution Sensing
In article number 2104706, Jingbin Zeng, Zifeng Yan, Yadong Yin, and co‐workers fabricate a hybrid pressure aerogel/hydrogel sensor by integrating a polypyrrole nanotube‐structured aerogel into a polyacrylamide hydrogel. With high stretchability and self‐healing property, the hybrid polymer sensor exhibits stable performance in high‐resolution sensing of a wide range of pressure...
Achieving high sensitivity over a broad pressure range remains a great challenge in designing piezoresistive pressure sensors due to the irreconcilable requirements in structural deformability against extremely high pressures and piezoresistive sensitivity to very low pressures. This work proposes a hybrid aerogel/hydrogel sensor by integrating a nanotube structured polypyrrole aerogel with a polyacrylamide...
