Abstract: An electrical tomography measurement device for a solid substrate includes a current or voltage source, electrodes connectable to a solid substrate to be measured and an analogue-to-digital converter comprising two measurement inputs and a reference input. The converter can output a digital signal corresponding to the difference between the voltage of the two measurement inputs proportional to a voltage level provided by the reference input. The current or voltage source can be controllably connected to a pair of electrodes, such that a current from the current or voltage source flows through the substrate to be measured in a chosen excitation sequence. The two measurement inputs of the analogue-to-digital converter can each be connected to a respective electrode of a pair of electrodes from the electrodes chosen according to the excitation sequence. The current or voltage source is connected to the reference input of the analogue-to-digital converter.

Abstract: A textile suitable for detecting movement and/or deformation comprises an electrically conductive fabric (8) which can expand in at least two directions, electrodes (12) arranged substantially regularly along the periphery of the fabric (8), a controller (14) designed to control the excitation of the electrodes (12) two by two according to a pattern such that all the electrodes (12) are successively excited, and to measure each time the voltage in the non-excited electrodes (12), and a computer (22) comprising a neural network inference engine and designed to receive the voltage measurements taken attire non-excited electrodes (12) in a given excitation cycle, in order to supply them to the neural network inference engine and to return a characteristic measurement of a movement having caused a deformation of the textile.
