摘要： A monolithic gas-sensing chip assembly for sensing a gas analyte includes a sensing material to detect the gas analyte, a sensing system including a resistor-capacitor electrical circuit, and a heating element. A sensing circuit measures an electrical response of the sensing system to an alternating electrical current applied to the sensing system at (a) one or more different frequencies, or (b) one or more different resistor-capacitor configurations of the system. One or more processors control a low detection range of the system to the gas, a high detection range of the system to the gas, a linearity of a response of the system to the gas, a dynamic range of measurements of the gas by the system, a rejection of interfering gas analytes by the system, a correction for aging or poisoning of the system, or a rejection of ambient interferences that may affect the electrical response of the system.

摘要： The sensor device comprises a hotplate on a membrane. The hotplate is heated by a N-fold rotationally symmetric heater structure having N>1 heater elements of identical design. Each heater element comprises an inner section, an intermediate section and an outer section arranged in series, with the inner section having a larger electrical cross section than the outer section. This design allows to heat the hotplate to a homogeneous temperature at moderate supply voltages.

摘要： Miniature resistive gas detectors incorporate thin films that can selectively identify specific gases when heated to certain characteristic temperatures. A solid state gas sensor module is disclosed that includes a gas sensor, a heater, and a temperature sensor, stacked over an insulating recess. The insulating recess is partially filled with a support material that provides structural integrity. The solid state gas sensor module can be integrated on top of an ASIC on a common substrate. With sufficient thermal insulation, such a gas detector can be provided as a low-power component of mobile electronic devices such as smart phones. A method of operating a multi-sensor array allows detection of relative concentrations of different gas species by either using dedicated sensors, or by thermally tuning the sensors to monitor different gas species.

摘要： A multifunctional fluid level and quality sensing device including a fluid level sensor and a capacitive sensor for detecting fluid level, fluid quality, errors in the sensing device, and issues in a fluid delivery system. In detecting fluid level, impedance of the capacitive sensor is used in improving sensing performance of the fluid level sensor, while in detecting fluid quality and errors in the sensing device, an expected impedance range with an upper boundary value and a lower boundary value is calculated, and a fault is generated when the measured impedance value is out of the expected impedance range. The fluid level and quality sensing device can also be used in a fluid delivery system for detecting system issues, and the results can be used for further isolating errors in the system. Operating status of higher level system provides more information for this purpose.

摘要： A gas sensor comprises a metal oxide sensing patch, a heater for heating the sensing patch, electrodes for measuring the conductivity of the sensing patch and an evaluation unit for generating a resulting parameter indicative of at least one analyte. Further, a temperature sensor is provided for measuring the temperature at the location of the sensing patch. The evaluation unit is adapted to derive a first parameter indicative of the conductivity of the sensing patch and a second parameter indicative of the heating power required to maintain a desired temperature of the sensing patch or indicative of the deviation of the temperature at the sensing patch from the desired temperature. The evaluation unit further combines the first and second parameters for evaluating the resulting parameter, thereby using the sensing patch not only as a chemiresistor but also as a pellistor-type measurement device.
