Surface Acoustic Wave Microbalance Development Kit - SAW-MDK1
| Surface Acoustic Wave (SAW) technology promises break-through advances for gas and liquid, chemical and biological analysis.
SENSeOR, the world-leading provider of acoustic-wave based sensor systems, is now proposing a development kit to allow the efficient development of respective chemical and biological sensors. The kit is a universal and adaptable platform to speed the development of highly sensitive coatings which react with very high sensitivity and selectivity to the presence of the media to be detected. Our electronic unit allows hand-held, autonomous monitoring in hostile environments with data being stored on-board or transmitted in real-time via a wireless or network channel.

Surface Acoustic Wave Microbalances offer largely improved performance for several key parameters when compared to the widely used QCM systems.
SENSeOR has developed the SAW-MDK1 with the objective to offer an optimal development tool for laboratory use. SENSeOR is in the process of adding additional novel capabilities – and is configured to develop custom optimizations and custom products. SENSeOR is your partner with unique expertise in SAW design and related microelectronics to achieve optimal performances of the sensors and of complete horizontal solutions in partnership with its client partners.

Description of the Development Kit
The SAW Cartridge is composed of a thermistor and two delay lines, one usable as reference and the other to be functionalized by a coating which is sensitive to the media to be measured.
SENSeOR is in the process of adding several types of cartridges, including versions with Microfluidics, various coatings like gold, electrochemistry, changed sensitivity, etc.. Please contact us for other requirements !
The Electronic Module serves the data acquisition, analysis and storage. An Ethernet link connects to the client software (multi-platform) which provides additional analysis and the user interface.
Again, two additional versions will be made available in order to provide a complete and optimal development capability.
| The main advantages of the SAW-MDK1 include:
Very high sensitivity : 400cm2/g
One cartridge with 2 SAW sensors + 1 thermistor
enabling measurements of up to 5 different parameters:
• Temperature
• Mass loading
• Viscosity
• Permittivity
• Conductivity
Coming soon : one cartridge with 5 sensors composed of different technologies
enabling simultaneous cross measurements to validate the results
• SAW sensors (as above)
• Electrochemistry
• Combined SAW/SPR allowing the extraction of coupled parameters: density, refractive index and thickness on the same layer.
• Transmission (UV/Vis)
|
|
Flexible use optimized for laboratory use:
• Very easy and flexible handling
• Microfluidics
• Protected reference sensor
Differential measurements using the integrated reference.
Real-time monitoring and Kinetic control (1s resolution) are features that allow envisioning revolutionary capabilities for medical and pharmaceutical diagnosis.
Direct detection of molecules: there is no need for preliminary marking by fluorescence or radioactive atoms – so no toxic rejections after analysis.
Large dynamic range
Low power requirements
Extremely reliable due to solid state design & fabrication and no moving parts.
Compatible with all QCM sensitive layers

Working Principle
A SAW die is sensitive to any substance contacting its surface : SAW chemical and biosensors take advantage of this property.
SAW sensors developed by SENSeOR are composed of two delay lines and one thermistor A very thin sensitive layer is deposited on the surface of a delay line or on both: the binding reactions on this surface are detected via one of the following methods:
- keeping one delay line as reference and the other to measure chemical or biological interactions between sensitive layer and the environment.
- using the two delay lines to measure different parameters, for instance the sensitive layer is a conductive material measuring mass load and viscosity. At the same time, the other delay line allows measurement of electric parameters like conductivity and permittivity.
