A hierarchical ZnO nanostructure gas sensor was fabricated to evaluate the concentration of acetone in exhaled human breath. Such information can be used for the diagnosis of diabetes since acetone levels in exhaled breath in excess of 1.8ppm are typically associated with diabetes sufferers. When exposed to acetone, the fabricated sensor exhibits a unique U-shaped response curve as a function of temperature...
Analyzing the concentration of acetone in human breath constitutes a promising non-invasive means to diagnose the onset of diabetes, with acetone levels of at least 1.8ppm typically associated to individuals suffering from diabetes. In this paper, we report the performance of a hierarchical ZnO nanostructure gas sensor for acetone detection. The fabricated gas sensor can detect concentrations as low...
