Hand-Held Electronic Nose to Detect Biomarkers of Diseases Through Breath

In this communication, we present a home-developed portable electronic nose used in discrimination of biomarkers of different diseases through the breath. We have used samples corresponding with different levels of gravity of illnesses. The electronic nose is equipped with embedded control, instrumentation electronics, rechargeable batteries, pump and electrovalve to control the way of the sampling gas, touch screen and IEEE 802.11 transceiver for wireless communication. Several measurements were made to check the discrimination capability of the prototype in the discrimination of different biomarkers of diseases.
