Development of a self-sufficient Ad Hoc Sensor to Perform Electrical impedance tomography measurements from within imaged space

Electrical Impedance Tomography (EIT) is an ill-posed problem whereby there are insufficient measured data to solve for a large amount of unknowns (finite elements). Conventionally, EIT measurements are performed on the boundary of an object or a process vessel. This results in a lower spatial resol...
