Abstract:
1. An actuator/sensor device comprising: a magnetic elastomer obtained by mixing a ferromagnetic material or a highly magnetic permeable material with an elastomer; a coil, further comprisina a continuous wire embedded within the magnetic elastomer in a configuration wherein adiacent portions of the wire are substantially parallel to one another, whereby generated magnetic flux penetrates the magnetic elastomer, and electrical connections to ends of the coil: wherein the coil further comprises a first torus coil and a second torus coil that are formed by bending a spiral coil, in which the lead is spirally wound, into a respective annular shape, wherein the first torus coil and the second torus coil are embedded in the magnetic elastomer in a state where central axes of the annular shapes are orthogonal to each other.
