Claim:
1. A sensor device, comprising: a magnetic viscoelastic elastomer containing electroconductive magnetic particles dispersed therein so as to demonstrate an elastic modulus that varies depending on a magnetic field applied thereto and an electric resistance in a prescribed direction that varies depending on a deformation thereof; a magnetic field application unit for applying a magnetic field that can be varied to the magnetic viscoelastic elastomer; a resistance detection unit for detecting the electric resistance of the magnetic viscoelastic elastomer; and a computation unit for computing a load applied to the magnetic viscoelastic elastomer according to a detection value of the resistance detection unit and a magnitude of the magnetic field applied by the magnetic field application unit, the computation unit being configured such that the greater the magnitude of the magnetic field applied by the magnetic field application unit is, the greater the value of the load computed for a given detection value of the resistance detection unit is.
