Abstract: A dielectric for a capacitive-based tactile sensor of the type having a pair of spaced apart conductive plates with the dielectric conductively therebetween, comprises a body of a non-rigid dielectric polymeric material. The body is shaped into a microstructure defined by a plurality of members adapted to extend from one of the conductive plates to the other. Some of the members comprises a first feature shaped to have a first end surface and a second end surface. Second features are integral with the first feature and project from the second end surface. A cross-section area of each of the second features is substantially smaller than a cross-section area of the first feature at the second end surface. A height of the first feature in a distance between the conductive plates is substantially greater than a height of the second features. A capacitive-based tactile sensor with the dielectric is also provided.
