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.

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.

Abstract: A compact microelectronic gas sensor module includes electrical contacts formed in such a way that they do not consume real estate on an integrated circuit chip. Using such a design, the package can be miniaturized further. The gas sensor is packaged together with a custom-designed Application Specific Integrated Circuit (ASIC) that provides circuitry for processing sensor signals to identify gas species within a sample under test. In one example, the output signal strength of the sensor is enhanced by providing an additional metal surface area in the form of pillars exposed to an electrolytic gas sensing compound, while reducing the overall package size. In some examples, bottom side contacts are formed on the underside of the substrate on which the gas sensor is formed. Sensor electrodes may be electrically coupled to the ASIC directly, or indirectly by vias.
