The RH sensing is measured by using a change in resistance of the material in different RH environments. Rhombohedral phase Ni3S2 nanostructure based flower-like structures were synthesized via a low cost microwave assisted hydrothermal method. The flowers were mounted on a device and analyzed for RH sensing. A sensing response of up to 116 times was achieved for the device at 63 % RH, which is higher than the response that has been reported for ZnS nanowires for 75 % RH. The evaluation of exhaled breath components by use of a gas sensor in order to improve the diagnosis and monitoring of respiratory and systematic diseases is growing very fast. The response measurement of the Ni3S2 device when exposed to human breath measured at different time intervals was investigated and preliminary results are presentedenBiomedical transducersDiseasesGas sensorsHumidity measurementHumidity sensorsMicrowave detectorsMicrowave measurementNanosensorsNickel compoundsPatient monitoringPneumodynamicsTemperature measurementTemperature sensorsNovel Ni3S2 based room temperature humidity sensor and potential breath analyzerArticleLinganiso, E., Coville, N., Mwakikunga, B.
