Measurement & Detection
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 ultra-low 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 derivative sensors can be integrated with slow, but accurate, moisture sensors, to achieve both ultra-high speed and accuracy in a single sensor system. Discussion on pPotential areas of applications such as s of these sensors such as monitoring inert, dry gas lines, glove boxes, lab process monitoring, breath monitoring, and speech recognition, etc. which that isthat are not possible with existing, commercial slower responding moisture sensors, will be discussed.
