Selective chemosensors based on the ferroelectric materials, mixed oxides, or temperature modulation of oxide polymorph stability

摘要

The present invention relates to gas sensors using doped ferroelectric materials. The sensors can be fabricated as an array where different portions of the array can operate at different independently controlled temperatures to detect different gas phase components of a gas sample. Preferred embodiments can be used for the diagnosis of conditions, such as, diabetes.
