Abstract: A colorimetric sensor film is disclosed. The colorimetric sensor film comprises a substrate and a sensing layer formed on the substrate, of which the sensing layer is able to change a visual color thereof after adsorbing a specific chemical substance contained in a target gas through physisorption or chemisorption. Moreover, a modular sensor device is also disclosed. The modular sensor device comprises a component housing containing a detection chamber and a reference chamber, a light source, said colorimetric sensor film, a detection optical sensor, a reference sensor film, a reference optical sensor, and a processor, in which the reference sensor film is able to exhibit a very low visual color change under different temperatures and humidity conditions. Therefore, the modular sensor device can detect at least one kind of gas and/or suspended matter in air with high selectivity, sensitivity and accuracy.

Abstract: A multi-use monitoring system is disclosed, which comprises an electronic device, multiple sensor devices, multiple cameras, at least one wireless interface, and a remote electronic device. According to the present invention, the sensor devices are adopted for detecting multiple environmental parameters such as gas level, humidity and temperature, and the multiple cameras are controlled to acquire images from the poultry bred in a breeding environment. Therefore, after receiving the images and the environmental parameters from the electronic device, the remote electronic device can extract at least one poultry characteristic from the images, and then correlate the environmental parameters to the poultry characteristic(s). As a result, the remote electronic device can subsequently calculate an evaluation score according to the growth and/or health state of the poultry, such that the breeder can plan how to distribute the breeding resources for the poultry.

Abstract: An area on a sensor chip (700) has a coating that contains fiber bundles (622) including a phage and is bioengineered to interact with a target analyte. A quartz crystal microbalance (QCM) or surface acoustic wave (SAW) sensing circuit, which may be connected to or integrated into the sensor chip (700), measures effects that result from interaction of the coating with the target analyte. Spin coating or spray coating may produce a coating suitable for QCM or SAM sensing techniques.

Abstract: A sensor system (100) or a sensing method minimizes the loss of aroma chemicals or other analytes in a sample gas while controlling the temperature and humidity of the sample gas. The system (100) may employ a humidifier (120) that adds water vapor to sample gas to provide a known water content, e.g., a saturated humidity at a known temperature. A sensing unit (130) may accurately measure the composition of the sample gas having a known water content, e.g., at a higher known temperature.
