Abstract

Electrical Impedance Tomography (EIT) is a method used to display, through an image, the conductivity
distribution inside a domain by using measurements taken from electrodes placed at its periphery. This
paper presents our prototype of a stretchable touch sensor, which is based on the EIT method. We then test
its performance by comparing voltage data acquired from testing with two different materials, using the
performance parameters Signal-to-Noise Ratio (SNR), Boundary Voltage Changes (BVC) and Singular
Value Decomposition (SVD). The paper contributes to the literature by demonstrating that, depending on
the present stimuli position over the conductive domain, the selection of electrodes on which current
injection and voltage reading are performed, can be chosen dynamically resulting in an improved quality of
the reconstructed image and system performance.
