Abstract: The present disclosure is directed to a selective multi-gas sensor device that detects when a high concentration level of a particular gas, such as methane, carbon monoxide, and/or ethanol, is present. The selective multi-gas sensor device detects and identifies a particular gas based on a ratio between a sensitivity of a gas sensitive material at a first temperature and a sensitivity of the gas sensitive material at a second temperature.

Abstract: The present disclosure is directed to a gas sensor that includes an active sensor area that is exposed to an environment for detection of elements. The gas sensor may be an air quality sensor that can be fixed in position or carried by a user. The gas sensor includes a heater formed above chamber. The gas sensor includes an active sensor layer above the heater that forms the active sensor area. The gas sensor can include a passive conductive layer, such as a hotplate that further conducts and distributes heat from the heater to the active sensor area. The heater can include a plurality of extensions. The heater can also include a first conductive layer and a second conductive layer on the first conductive layer where the second conductive layer includes a plurality of openings to increase an amount of heat and to more evenly distribute heat from the heater to the active sensor area.

Abstract: A universal electrochemical micro-sensor can be used either as a biosensor or an environmental sensor. Because of its small size and flexibility, the micro-sensor is suitable for continuous use to monitor fluids within a live subject, or as an environmental monitor. The micro-sensor can be formed on a reusable glass carrier substrate. A flexible polymer backing, together with a set of electrodes, forms a reservoir that contains an electrolytic fluid chemical reagent. During fabrication, the glass carrier substrate protects the fluid chemical reagent from degradation. A conductive micromesh further contains the reagent while allowing partial exposure to the ambient biological or atmospheric environment. The micromesh density can be altered to accommodate fluid reagents having different viscosities. Flexibility is achieved by attaching a thick polymer tape and peeling away the micro-sensor from the glass carrier substrate. The final structure is thereby transferred to the polymer tape, providing a flexible product.

Abstract: The present disclosure is directed to a gas sensor device that detects gases with large molecules (e.g., a gas with a molecular weight between 150 g/mol and 450 g/mol), such as siloxanes. The gas sensor device includes a thin film gas sensor and a bulk film gas sensor. The thin film gas sensor and the bulk film gas sensor each include a semiconductor metal oxide (SMO) film, a heater, and a temperature sensor. The SMO film of the thin film gas sensor is an thin film (e.g., between 90 nanometers and 110 nanometers thick), and the SMO film of the bulk film gas sensor is an thick film (e.g., between 5 micrometers and 20 micrometers thick). The gas sensor device detects gases with large molecules based on a variation between resistances of the SMO thin film and the SMO thick film.

Abstract: A semiconductor-based multi-sensor module integrates miniature temperature, pressure, and humidity sensors onto a single substrate. Pressure and humidity sensors can be implemented as capacitive thin film sensors, while the temperature sensor is implemented as a precision miniature Wheatstone bridge. Such multi-sensor modules can be used as building blocks in application-specific integrated circuits (ASICs). Furthermore, the multi-sensor module can be built on top of existing circuitry that can be used to process signals from the sensors. An integrated multi-sensor module that uses differential sensors can measure a variety of localized ambient environmental conditions substantially simultaneously, and with a high level of precision. The multi-sensor module also features an integrated heater that can be used to calibrate or to adjust the sensors, either automatically or as needed. Such a miniature integrated multi-sensor module that features low power consumption can be used in medical monitoring and mobile computing, including smart phone applications.

Abstract: An electronic device is formed by depositing polyimide on a glass substrate. A conductive material is deposited on the polyimide and patterned to form electrodes and signal traces. Remaining portions of the electronic device are formed on the polyimide. A second polyimide layer is then formed on the first polyimide layer. The glass substrate is then removed, exposing the electrodes and the top surface of the electronic device.
