“…A system of shear sensors for measuring forces applied at the tactile interface is a requirement to replicate the force that is attained in a typical human hand. This goal is accomplished by the introduction of a shear sensor capable to detect incipient slip, the detection of shear forces directly, and the calculation of the necessary normal grip force to maintain control on the given object shown in figure 23 [39,91,152,171]. Nelson et al reported the use of the tactile sensor for robotic applications which is highly sensitive to pressure and also responds to shear force [172].…”

Shear sensors are used for measuring shear stress and shear strain in solid bodies when mechanical forces are applied. For the preparation of these sensors, researchers reported innovative materials either alone or in the form of blends, alloys, and composites. Shear sensors are not easily available for purchase, therefore, this review focuses on the working principles of various kinds of shear sensors being explored by researchers. Several technologies and materials are used, such as piezoelectric materials, piezoresistive materials, fiber Bragg grating, capacitive sensing, and structural colors. This article also looks at fabrication-based challenges that restrict the commercial use of shear sensor. A variety of shear sensors devices are evaluated for measuring shear stress/strain for many different application such as health monitoring and biomedical, robotics, and or fracture in materials.

“…In dielectric elastomer sensors (DES) a change of the electric capacitance can be measured when the elastomer film is mechanically deformed by an external force [14][15][16][17][18]. The capacitance of the compliant capacitor is enhanced by the increase of the electrode area and the simultaneous decrease of the distance between the electrodes upon the deformation, resulting in a very simple load sensor.…”

Influence of design and material properties on the performance of dielectric elastomer compression sensors

New designs of dielectric elastomer sensors (DES) which are capable to detect compression loads on rigid as well as on compliant surfaces are introduced in this paper. Currently, DES films exhibit only very poor sensitivity in terms of the change of electric capacitance upon increasing loads for compression measurements. In the new sensor mats, the compression load is converted to a tensile load which acts on an elastomer film located between two profiled elastomer components. In addition, the deformation of the elastomer profiles can also contribute to the sensor effect. All elastomer components were prepared of silicone. A number of parameters which have an influence on the characteristic dependence of capacitance on compression load are discussed. A main influence results from the shape of the elastomer profiles which stretch the elastomer film inside. Also very important are the number and the locations of electrode layers in the sensor mat between which the capacitance is measured. Finally, the hardness of the elastomer plays also a decisive role for the sensor sensitivity. This broad variability of the sensor design offers a high potential to tune the sensor characteristics. Various examples of compression sensors are described and the impact of structural and material parameters is discussed
