SENSOR DEVICE AND METHODS

WIPO Patent Application WO/2018/208355

A3

Device and method for detecting presence of a hazardous material in an environment or through a testing material, such as for example, a protective material. The device may include a sensor for detecting presence of the hazardous material. In particular, the hazardous material may have a vapor pressure of less than 0.5 mmHg. The sensor comprises a conductive polymer, a semi-conductive polymer or an electroactive polymer, the sensor being chemically reactive with the hazardous material to generate a change in electrical resistance in the sensor. The device may include one or more conductive electrodes attached to the sensor configured to detect change in resistance in the sensor, and a resistance measuring device electronically connected to the one or more electrodes for receiving data from the electrodes and generating an output based on the data corresponding to an amount of hazardous material detected by the sensor in real-time.
