  • InGaZnO (IGZO) based system for gas detection at room temperature
    Patent number: 11867657
    Abstract: A gas sensor includes a gate electrode; a dielectric layer covering one surface of the gate electrode; an indium (In) gallium (Ga) zinc (Zn) oxide (O) (IGZO) thin-film formed over the dielectric layer, and first and second metallic electrodes formed on a surface of the IGZO thin-film to act as source and drain, respectively. The IGZO thin-film has an In concentration of 11%+/?3%, Ga concentration of 11%+/?3%, Zn concentration of 7%+/?3%, and O concentration of 71%+/?3%, with a sum of the concentrations being 100%, and the gas interacts with the IGZO thin-film and changes a current through the IGZO thin-film.

  • SOIL MOISTURE DETECTION SENSOR HAVING METAL-ORGANIC FRAMEWORK AND METHOD
    Publication number: 20230094121
    Abstract: A moisture sensor is configured to be deployed in soil for measuring a moisture content. The moisture sensor includes a housing; a transistor configured to interact with water from the soil; a power source configured to generate an electrical current; and a processing unit configured to receive a reading from the transistor, and to calculate the moisture content of the soil based on the reading. The transistor includes a metal-organic framework, MOF.

  • METAL-ORGANIC FRAMEWORK COATED ORGANIC FIELD EFFECT TRANSISTOR BASED NO2 SENSOR AND METHOD
    Publication number: 20230060532
    Abstract: An NO2 detection device includes a substrate; a drain formed on the substrate; a source formed on the substrate; a p-type polymer semiconductor layer formed on the substrate, between the drain and the source; and an n-type metal-organic framework layer located over the p-type polymer semiconductor layer. The n-type metal-organic framework layer has apertures having a size larger than a size of the NO2 molecules so that the NO2 molecules pass through the n-type metal-organic framework layer to arrive at the p-type polymer semiconductor layer to increase an electrical current.
