Solutions and Sensor Modules for Customized Applications
The range of applications using the Pt thin-film technology extends well beyond the manufacture of classicPt temperature sensors.
The multi-functionality concept utilizing platinum thin-film technology has been applied to create sensor modules.
The designs range from straightforward single-chip sensor/heater combinations, to complex multiple feature chips containing sensors, heaters, electrodes, and other components.
For our customers, there is also an option to apply sensitive layers on the electrode: Through the use of metal oxides, for example, multi-sensor platforms become gas sensors capable of measuring concentrations of oxygen, carbon monoxide, nitrogen or methane, down to the ppm range.
In addition to applications in gas and humidity measurement, platform chips customized for aqueous media analysis in biomedical technology applications, and other similar applications, are possible.
Heraeus Nexensos, a specialist and leader in platinum thin-film technology, is your first contact and development partner in the area of multi-sensor platforms with custom designed Pt structures for sensors, heaters or electrodes in mono- or multi-layer design.
