Gas Sensitivity Amplification of Interdigitated Chemocapacitors Through Etching

“…Agreement between the simulation and experimental data is demonstrated for all layouts. For the capacitance measurement, a miniaturized module based on the commercial 24-Bit Capacitance-to-Digital Converter is used [7], that allows for the measurement of capacitance changes of 1fF. The real resistance of IDEs, with DC excitation signal, was measured to be over 100Mohm.…”

K. Ntetsikas, G. Polymeropoulos and N. Hadjichristidis would like to IDEs have been mainly explored for the detection of analytes in air focusing primarily on the detection of harmful or toxic substances [1][2][3][4][5][6][7][8][9] but research effort has been also directed towards the detection of Volatile Organic Compounds (VOCs) in soil and liquids [10][11][12][13]. In the applications related to the detection of analytes in air, IDEs are usually coated with polymeric materials with selective absorbance of particular analytes.…”

Ultra miniaturized InterDigitated electrodes platform for sensing applications

“…One very promising sensing concept is the chemocapacitor [1][2][3][4] where the change in the dielectric permittivity of the layer between the capacitor's electrodes results in change in the capacitance value. The chemocapacitor is fabricated with mature and easy microelectronic processes and has a sensing layer between the two electrodes.…”

Development of a Colorimetric Sensor for Autonomous, Networked, Real-Time Application

“…Finally, detection may occur sooner as threats do not have to diffuse to a centralized detector but will instead encounter devices at the perimeter and throughout the area. Various detection methods have been tested in sensor networks [ 31 , 32 , 33 , 34 , 35 ]. There are several topics that remain active areas of focus, such as controlling power use [ 31 , 36 , 37 , 38 ] and determining the best way to deploy the sensors [ 39 , 40 , 41 , 42 ].…”
