NEW PRODUCTS! Synkera has launched three new sensor products: Planar Interdigitated Electrodes, as well as Low-Power H2 and Low-Power VOC microsensors. Follow the links for further info.


Sensors: Chemiresistors

MOS Sensor Operating Principles:

• Gas adsorption on surface of the metal oxide changes electrical resistance.
• Reducing gas donates electrons and oxidizing gas "grabs" electrons.
• Change in resistance is a surface reaction and dependent upon the amount of surface area.
• Surface interactions occur at elevated temperatures.

Synkera NanoMOS™ sensors features/benefits

• Three unique sensor architectures:
     • Planar sensors prepared via a thick film
       screen printing process
     • Multilayer sensors
     • MEMS sensors for low power and
       advanced operating modes
• Small size
• Improved sensitivity
• Low cost
• Fast Response

Operation of Planar and Multilayer MOS Sensors

• Sensor Resistance is a function of analyte concentration
• Log (resistance) is proportional to Log (concentration)
• Power required for heater operation of 100 mW to 1W.
