Towards high precision electrical capacitance tomography multilayer sensor structure using 3D modelling and 3D printing method

3D ECT sensors are responsible for detecting spatial capacitance changes caused by spatial changes in electrical permittivity. In this paper authors propose a novel approach to the 3D ECT sensors fabrication process that use 3D computer modelling and 3D printing to easily get any sensor shape, electrode layout, scale and shielding strategy. The proposed method is much faster, more flexible and accurate than previously used hand-made approach. This paper compares and analysis the measurement abilities of a 3D ECT sensor made with traditional hand-made technique with a device printed using a new approach.
