Summary on Grant Application Form |
|
The primary project objective is the construction of a pre-production, prototype, highly-portable, hand-held, artificial electronic nose. The entire electronics, sensor-array, and odour sampling system which compromise the device will be housed in an enclosure typically the size of a personal organizer. Integrated analogue and digital electronics will be developed with the objective of reducing component count and power consumption, The system will compromise an analogue ASIC front end, a digital back-end based on a lower power RISC microprocessor for pattern recognition and integrated glue logic. The user interface will consist of a keypad and liquid crystal display unit.The sensors themselves are sensitive to temperature and humidity. The sensing array is, therefore, operated several degrees above ambient temperature. A combination of planar-processing and bulk-micromachining technologies will be used to produce low-power silicon substrates. The sensing array will be thermally isolated from the substrate on a low heat capacity polymide membrane which will also support a platinum heater/thermometer. New measuring techniques will also be developed, utilising appropriate bridge techniques, to achieve humidity compensation. In order to detect the chemicals associated with fungal infestation of wood, suitable chemical sensors will also be developed, or optimised, from existing sensor materials.
