Based on the results of studies on acetone excretion in diabetic patients, a one - chip sensors array was fabricated by combining ace- tone-selective sensor materials and volatile-organic-compound sensitive sensor materials. An electonic-nose was implemented using asensor array and confirmed selectivity for five gases. In this system, the excretion of diabetic patients and controls was sampled withsolid phase microextraction fiber and transferred to the sensor array. Although the control and diabetic patients were distinct, several samples failed. In the control group, the results of blood tests were normal, but patients were highly obese. In addition, the gas chro- matography mass spectrometry results for the subjects revealed chemicals that are external factors
