Abstract
To provide a distribution measuring sensor system and the like having a high spatial resolution and can greatly reduce a wiring region even if many sensor units for the measurement of a contact pressure and a shear stress acting on an interface between a living body and an object are integrated. A distribution measuring sensorhas a configuration in which sensor units Uij which measure a shear stress in a direction of a plane and a contact pressure in a direction perpendicular to the plane are arranged at each element of a matrix M. The sensor units Uij are constituted of an upper electrode UijH common to measurement of the shear stress and the contact pressure, and a lower electrode UijL arranged below the upper electrode UijH through a pressure sensitive material. Each sensor unit Uij in the x axis direction arranged in the same column j of the matrix M has each upper electrode UijH connected in the column j direction in common through the connecting line Cj. Each sensor unit Uij in the y axis direction arranged in the same row i of the matrix M has each lower electrode UijL connected in the row i direction in common through the connecting line Ri.
