1. A resistance device, comprising:

  • a variable viscosity material capable of undergoing a change in flow characteristics in response to an applied field;

    a moving member having at least one surface in contact with the-variable viscosity material so that the change in flow characteristics of the variable viscosity material variably resists movement of the moving member depending on the applied field;

    applying means for applying the applied field to the variable viscosity material;

    an opposing member disposed in opposing facing relationship with the moving member;

    a spacer member disposed for maintaining a gap between the moving member and the opposing member, the spacer member having a variable thickness for selectively varying the gap between the moving member and the opposing member.
