MRS Proceedings, 2005
AbstractColor information is commonly captured by silicon sensor arrays covered by a mosaic of color filters. However, the detection of the colors red, green and blue at different spatial positions of the sensor arrays leads to color aliasing or color moiré effects. This effect inherently limits conventional sensor arrays.

ZnO-thin film chemical sensors
Fresenius' Journal of Analytical Chemistry, 1994The properties of reactively sputtered ZnO thin films used as chemical sensors are investigated in N2, synthetic air, 10 ppm of NO2, 30 ppm of CO and in the presence of humidity. The behaviour is correlated to a grain boundary determined conduction model. Using the resistance ratio of twin sensors, one of which is coated with a thin Au catalytic layer,

A thin film temperature sensor
Journal of Vacuum Science and Technology, 1975Using vacuum−deposition techniques, a thin film thermistor has been developed. The device consists of a tin selenide sensing material, platinum leads, and quartz encapsulation deposited on a 1/4 mil kapton substrate. The resistance of a typical sensor shows increases of 2 1/2 orders of magnitude for a corresponding temperature decrease from 30 to −130 ...

Thin Film Diamond Sensor Technology
Physica Status Solidi (a), 1996Modern thin film sensor technology imposes stringent demands upon material quality, highly qualified downstream process technologies, device performance and integrity. Since the earliest stages of its development, crystalline thin film diamond has been promoted as a semiconductor material for high power, high frequency or high temperature electronics ...

Polypyrrole thin films gas sensors
Synthetic Metals, 2001Thin films of polypyrrole doped with different counter-ions, prepared by in situ polymerization on conducting glass electrodes, are used for the development of gas sensors with fast response time. On exposure to a given vapor, each individual film exhibits a fast change in the fractional difference of its electrical resistivity and with the adopted ...

Semiconductor MoO3–TiO2 thin film gas sensors
Sensors and Actuators B: Chemical, 2001Abstract The O 2 , CO and NO 2 gas sensing properties of MoO 3 –TiO 2 thin films have been studied. The sol–gel process was employed to fabricate MoO 3 –TiO 2 thin films onto sapphire and alumina transducers for gas sensing measurements. It was found the MoO 3 dominated sensors have a lower optimal operating temperature of 370°C than the TiO 2 ...

Thin film transducers and sensors
Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 1986The transducers discussed are those which make use of the unique features of thin films. These include metal and semiconductor film strain gauges and manganin high pressure gauges for use in lubricated bearings. Optical transducers include photoresistors, vidicon screens, solar cells, and IR detectors with special reference to the use of hydrogenated ...
