Development of Electronic-Nose Technologies for Biomedical Applications.

In this paper the development of an electronic nose for biomedical applications is reported. The key concept guiding the development of the analyzer has been the portability, its easy use, and interface with the patient and hospital facilities. With this in mind, a small analyzer with an e-nose, comprising commercial gas sensors and a breath sampling device, was assembled and tested. After the calibration tests carried out in laboratory, the real-time breath monitoring of patients under hemodialysis treatment has been performed to validate the developed analyzer. © 2014 Springer International Publishing Switzerland.
