Electromechanical Boundary Impedance Tomography


"We propose a novel tactile sensing method for imaging pressure distribution on an object based on electromechanical boundary impedance tomography (EmBIT). The sensor consists of driving and probing layers which are electromechanically coupled according to the pressure and the system solves an optimization problem to find the electromechanical boundary impedance related to contact pressure. The potential at each electrode is used to find the electrical boundary condition between the layers. The proposed method can be customized for an object of arbitrary shape."
