Abstract 

This paper presents the theory and key experimental findings for an investigation into the generation of bimodal resonance

(frequency splitting) phenomena in mutually over-coupled inductive sensors, and its exploitation to evaluate relative separation and

angular displacement between coils. This innovative measurement technique explores the bimodal resonant phenomena observed

between two coil designs - solenoid and planar coil geometries. The proposed sensors are evaluated against first-order analytical

functions and finite element models, before experimentally validating the predicted phenomenon for the different sensor configurations.

The simulated and experimental results show excellent agreement and first-order best-fit functions are employed to predict

displacement variables experimentally. Co-planar separation and angular displacement are shown to be experimentally predictable

to within ±1mm and ±1o using this approach. This study validates the first-order physics-based models employed, and demonstrates

the first proof-of-principle for using resonant phenomena in inductive array sensors for evaluating relative displacement between

array elements.

Instructions: 

The data is the displacement linear and angular for solenoid and PCB coils, the data contains the resonance bimodal frequency for both designs, the resonance is measured in voltage.

The paper displacement sensing using bi-modal resonance in over-coupled inductors explains the process and the methodology
