Ultrafast, Highly Sensitive Printed Moisture Sensors for High-Speed Sensing Applications

Dr. Vijaya Kayastha's 2017 Sensors Expo & Conference Presentation

2017 Sensors Expo PresentationUltrafast, Highly Sensitive Printed Moisture Sensors for High-Speed Sensing Applications

An ultra-fast printed moisture sensor with high moisture sensitivity will be presented. These carbon-based, resistive-type sensors have almost instantaneous response to humidity fluctuation, with a response time of less than 10 milliseconds. The sensors are very sensitive to moisture, and are able to detect a moisture at a trace level of < 100 ppm. The sensors can operate at ultralow power (<30 pW), have a flexible form factor, can be printed on any surface, and can be integrated with many existing devices. In addition, these sensors can be integrated with slow, but accurate, moisture sensors, to achieve both ultrahigh speed and accuracy in a single sensor system. Discussion on potential applications such as monitoring inert dry gas lines, glove boxes, lab process monitoring, breath monitoring, and speech recognition, that are not possible with existing, commercial moisture sensors, will be discussed.
