Abstract
A single volume soft sensor capable of sensing real-time continuous contact and stretching. An electrical impedance tomography (EIT) technique with support vector machine (SVM) learning is employed to estimate changes of resistance distribution on the sensor caused by fingertip contact even during sensor deformation events. A deformation switch is incorporated to maintain the localization during deformation events.
