A New Concept for Humidity Sensing Using Curved Micro-beams

Ouakad H.M., Hasan M.H., Alsaleem F.M., University of Nebraska Lincoln, US

There are number of common humidity sensing methods in MEMS. They include capacitive, resistive, and thermal methods. Among these methods, capacitive sensing is considered the most common in MEMS. In this method, changes of a [...]

A New Pressure Threshold Sensor Based on Nonlinear MEMS Oscillator

Alsaleem F., Hasan M.H., University of Nebraska Lincoln, US

Pressure sensing is one of the earliest applications of Micro-Electro-Mechanical-Systems MEMS. Changing the pressure sensing element (such as capacitive and optical) size to the microscale has created opportunities to reduce power consumption and production costs [...]

A new humidity sensor based on the effect of water content on a capacitive MEMS oscillator’s thermo-electrical characteristics

Alsaleem F., University of Nebraska Lincoln, US

Accurate humidity measurement is essential in commercial and industrial applications such as HVAC systems and microelectronics manufacturing. Typical humidity sensors suffer from degradation over time, consume a relatively high amount of power, and have limited [...]

Capturing and Using CO2 as Feedstock for Clean Chemical Processes Technologies

Demirel Y., University of Nebraska Lincoln, US

Chemical-looping technology for capturing CO2 are discussed with critical assessments of the circulating fluidized bed systems and the packed bed reactor with periodic switching of the feed streams of fuel and air. Beside, some industrial [...]
