Transilient Response to Acetone Gas Using the Interlocking p+n Field-Effect Transistor Circuit
2018
Sensors
Low concentration acetone gas detection is significantly important for diabetes diagnosis as 1.8-10 ppm of acetone exists in exhaled breath from diabetes patients. A new interlocking p+n field-effect transistor (FET) circuit has been proposed for Mn-doped ZnO nanoparticles (MZO) to detect the acetone gas at low concentration, especially close to 1.8 ppm. It is noteworthy that MZO in this interlocking amplification circuit shows a low voltage signal of <0.3 V to the acetone <2 ppm while it
