摘要: Diabetes is one of the most rapidly-growing chronic diseases in world. Acetone, a volatile organic compound exhaled breath, shows positive correlation with blood glucose and has proven to be biomarker for type-1 diabetes. Measuring level acetone breath can provide non-invasive, low risk infection, cost, convenient way monitor health condition diabetics. There been continuous demand improvement this sensitive sensor system fast real-time electronic readout levels. A novel nanostructured K₂W₇O22 recently used test concentration from 0 parts-per-million (ppm) 50 ppm at room temperature. The results revealed that response acetone, but detection limit not ideal due limitations device. In paper, we report an improved sensitivity by using optimized circuit minimize noise increase signal ratio purpose weak while very low.
