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)

摘要： Provided are a bending sensor that is less dependent on an input speed of a strain and in which a response delay is unlikely to occur, and a deformed shape measurement method using the bending sensor. The bending sensor is configured to include a base material; a sensor body arranged on a surface of the base material and containing a matrix resin and conductive filler particles filled in the matrix resin at a filling rate of 30% by volume or more, and in which three-dimensional conductive paths are formed by contact among the conductive filler particles, and electrical resistance increases as an deformation amount increases; an elastically deformable cover film arranged so as to cover the sensor body; and a plurality of electrodes connected to the sensor body and capable of outputting electrical resistances. In the sensor body, cracks are formed in advance in such a direction that the conductive paths are cut off during a bending deformation.
