CSRR Based Sensors for Relative Permittivity Measurement With Improved and Uniform Sensitivity Throughout [0.9–10.9] GHz Band

IEEE Sensors Journal, 2020
This paper proposes miniaturized, lightweight and high sensitivity planar metamaterial based sensors for relative permittivity measurement within [0.9–10.9] GHz band. Each proposed sensor is designed using a thin-substrate microstrip line loaded with a single complementary split ring resonator (CSRR).

Relative Permittivity Meter Using a Capacitive Sensor and an Oscillating Current Source

IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019
The relative permittivity (also known as dielectric constant) is one of the physical properties that characterize a substance. The measurement of its magnitude can be useful in the analysis of several fluids, playing an important role in many industrial processes.

A Relative Permittivity-Based Air Pressure Sensor Using Standard CMOS Process

IEEE Sensors Journal, 2017
In this paper, a novel pressure-sensing technique based on measuring the relative permittivity of air is introduced. Previous works in this area are mostly centered around mechanical sensors paired with electrical readout circuits. However, the proposed CMOS-based pressure sensor is able to achieve the full sensing process electrically, from the ...

An Error Compensation Algorithm for Indirect Resonant Planar Relative Permittivity Sensor Principles up to 100 GHz

2019 IEEE MTT-S International Microwave Workshop Series on Advanced Materials and Processes for RF and THz Applications (IMWS-AMP), 2019
This paper presents an error compensation algorithm for indirect resonant planar relative permittivity sensor principles up to 100 GHz. Besides the measurement of the material under test (MUT), the algorithm requires additional measurements of at least two reference materials. The proposed algorithm is tested for the three most relevant modeling errors
