Abstract
This paper presents a concept of a tactile sensor based on multiple planar coils with overlapping regions and a magnetosensitive elastomer layer. The sensor setup is simplified to a two-dimensional problem. Experimental investigations are compared with an electro-mechanical model. This model is able to simulate inductance changes of less than 0.1% caused by a deformation. The trend of the modeled curves fits the experimental data in a way to draw conclusions about the range and dependency of the inductance change on the depth of indentation.
