The sensor response of six different polymer-carbon-black composite sensors to three different analytes has been investigated as a function of temperature where the temperature range is 28-36°C (ΔT is 4-8°C). We tested the response of these polymer-carbon-black sensors to water, methanol and methane from 28-36°C. All of the sensors showed a decrease in response to an analyte with increasing temperature; however, each sensor's response changes differently with temperature. This variation of response to temperature change creates distinct temperature-dependent fingerprints and will be useful in extending the range of data available for analyte identification and quantification.
