Smart Cable Air

SCA is a multi-sensor microsystem (MSM) to monitor for the presence of toxic chemicals (TICs), pollutants, volatile organic compounds (VOCs) and flammable gases in air.

At the core of SCA there is SENSIPLUS, the Sensichips microsensor platform that can interrogate on-chip and off-chip sensors with its versatile and accurate Electrical Impedance Spectrometer (EIS). Analytics  performed with EIS allow to exploit chemisorption or ReDox dynamics of the sensitive film to aid gas discrimination. Alternate Current (AC) readout is less sensitive to drifts plus EIS allows to derive an R/C equivalent circuit of the sensor to decouple components that drift from the ones that represent the response to the gas, in support of drift mitigation algorithms. Thanks to its versatile analytical instruments and availability of on-board Interdigitated Electrodes, SCA is also an excellent experimental board for new sensitive materials. Several SCAs can be installed onto long cables for large area continuous monitoring.
