Abstract: Printed resistive-based sensors and transducers comprising a thin, electronically “active” sensing layer within a dielectric and/or metallic layered structure are provided. The electronic resistance of the active sensing layer is measured during a change in the sensor environment. By utilizing a multi-layered architecture around the active sensing layer, the electronic signal of the sensing element can be improved. By carefully selecting the architecture and materials that surround the active sensing layer, the sensitivity, stability, and selectivity of the sensor to detect changes in the environment are improved. This design allows for a number of specific application areas for environmental sensing.

Abstract: A carbon nanotube sensor device for detecting CO2 and methods of its production and use. A printable polyethylenimine (PEI)-functionalized carbon nanomaterial paste may be used to form the active sensing layer of the device, which is particularly sensitive to CO2. A separate printed heating layer may be used to maintain the working temperature of the sensor, as well as to remove and/or clear volatile gases from the sensor.
