Resistive gas sensors have received a bad reputation of being largely non-selective.
Our work has produced a crystallo-chemical model for selective gas sensing by polymorphic
metal oxides. The reaction-based and ferro-electric poling sensing mechanisms are discussed
in detail. Novel processing methods to produce the respective nano sensors are presented along
with the device fabrication for the non-invasive diagnosis of gaseous biomarkers in human
and animal breath or skin. This sensor technology is expected to revolutionize medical diagnostics.
