- The AWM40000 Series Airflow Sensors are based on proven microbridge technology and include both unamplified sensor-only devices and amplified signal conditioned devices.
- The microbridge mass airflow sensor operates on the theory of heat transfer.
- Mass airflow is directed across the surface of the sensing elements.
- Output voltage varies in proportion to the mass air or other gas flow through the inlet and outlet ports of the package.
- This sensor has a unique silicon chip based on advanced microstructure technology.
- It consists of a thin film, thermally-isolated bridge structure containing heater, and temperature sensing elements.
- The bridge structure provides a sensitive and fast response to the flow of air or other gas over the chip.
- Dual sensing elements positioned on both sides of a central heating element indicate flow direction as well as flow rate.
- The specially-designed housing precisely directs and controls the airflow across the microstructure sensing element.
- Mechanical design of the package allows it to be easily mounted to printed circuit boards. Laser-trimmed, thick film and thin film resistors provide consistent interchangeability from one device to the next.
- The microbridge mass airflow sensor uses temperature sensitive resistors deposited within a thin film of silicon nitride.
- They are suspended in the form of two bridges over an etched cavity in the silicon.
- The chip is located in a precisely dimensioned airflow channel to provide a repeatable flow response.
- Highly effective, thermal isolation for the heater and sensing resistors is attained by etching the cavity space beneath the flow sensor bridges.

Flow sensors are devices used for measuring the flow rate or quantity of a moving liquid or gas (22). New materials have been introduced into flow sensors to improve their performance. Among them, CNTs were introduced into flow sensors by Ghosh et al. in (130). It was found that current/voltage in a bundle of SWCNTs will be generated along the direction of the flow when SWCNTs were used in the flow sensor. The authors suggested that the dominant mechanism responsible for this highly nonlinear response involves a direct forcing of the free charge carriers in the nanotubes by the fluctuating coulombic field of the liquid flowing past the nanotubes. However, pristine SWCNTs contain carbonaceous and metallic impurities that influence their electrochemical performance. Later, Escarpa et al. used the high near-infrared purity index SWCNTs to design microfluidic chips (131). In this work, a set of 0.1 mg/mL SWCNT dispersions with different degrees of purity and different dispersants was carefully characterized by near-infrared spectroscopy (Fig. 5.5). These dispersions were utilized to modify microfluidic chip electrodes for electrochemical measurement of dopamine and catechol. In comparison with a non-SWCNT-based electrode, the sample with the highest purity exhibited the best analytical performance in terms of improved sensitivity, very good signal-to-noise ratio, high resistance to fouling, and enhanced resolution.
Such work is the first demonstration of the sensitivity–purity relationship in SWCNT microfluidic chips.
