摘要： A crosslinked elastomer body is composed of an electrically conductive composition comprising an electrically conductive filler and an insulative elastomer (matrix). The electrically conductive filler is in a spherical particulate form and has an average particle diameter of 0.05 to 100 μm. The electrically conductive filler has a critical volume fraction (φc) of not less than 30 vol % as determined at a first inflection point of a percolation curve at which an insulator-conductor transition occurs with an electrical resistance steeply reduced when the electrically conductive filler is gradually added to the elastomer. A resistance observed under compressive strain or bending strain increases according to the strain over a resistance observed under no strain when the electrically conductive filler is present in a volume fraction not less than the critical volume fraction (φc) in the composition.

摘要： A deformable sensor system that can be used for pressure-distribution sensors. The deformable sensor system makes it possible to obtain a pressure distribution with a much higher accuracy, while reducing the number of electrodes. The system utilizes a deformable sensor which can detect deformation as the electric resistivity of the surface increases monotonically as an elastic deformation variation in each of the elastic deformations increases. Based on a voltage being detected by means of a detecting unit, the deformable sensor electric-resistivity variation computing unit computes the variation of the electric resistivity based on the method of least squares with a restriction condition imposed thereon. The system uses such a technology as “EIT” that is based on an inverse-problem theory. At an external-force position computing unit, a position in a pressure-receiving surface, position which receives an external force, is computed based on the computed electric-resistivity variation.

摘要： To provide a deformable sensor system, which makes it possible to obtain a pressure distribution with a much higher accuracy, while reducing the number of electrodes.A deformable sensor 12 comprises an elastic material whose electric resistivity, when all types of elastic deformations are caused therein respectively, increases monotonically as an elastic deformation variation in each of the elastic deformations increases. Based on a voltage being detected by means of a detecting unit 22, the deformable sensor 12's electric-resistivity variation δρ(x, y), which minimizes an evaluation Function J of Equation (1) while satisfying a condition of Equation (2), is computed at an electric-resistivity variation computing unit 25 using such a technology as “EIT” that is based on an inverse-problem theory. At an external-force position computing unit 26, a position in a pressure-receiving surface 12a, position which receives an external force, is computed based on the computed electric-resistivity variation δρ(x, y). J=∥δV(m,n)−Sm,n,x,y·δρ(x,y)∥2 (1) However, δρ(x,y)≧0 (2)
