Systems and methods for generating smell data and a database thereof

A system comprising a sensor and a database, the database comprising:

• a digital signature of a smell comprising a smell data, wherein the smell data comprises a response signal that is a function of a first data corresponding to a material type (generator) generating the response signal and a second data corresponding to a predetermined stimulus operable to generating the response signal;
• a smell condition data associated with the smell data, wherein the smell condition data comprises a condition under which the smell data was generated;
• and
• an index for the smell data;
• wherein the smell data is stored in a data structure on a computer readable storage medium that is associated with a computer executable program code;
• wherein the data structure comprises the smell data arranged in a computer-readable matrix or heat-map format;
• and
• wherein the response signal is a measurable response of the generator to the predetermined stimulus that is a function of change in electrical properties of resistance or impedance in the generator.
