1. A haptic feedback device for providing haptic feedback to an arm of a user comprising:
a modular section, the modular section comprising:
an anchor component having a first impedance coupled to the skin of the arm at a first location;
a low mass component having a second impedance coupled to the skin of the arm at a second location;
an inertial mass component having a third impedance mechanically coupled to said anchor component and to said low mass component via one or more couplings; and
configured to provide actuation thereto; and
wherein said first impedance is larger than said second and third impedances, so that upon said actuation said low mass component is displaced by a larger amount than said anchor portion, said displacement of the low mass component moving a portion of the skin proximate said second location thereby creating a haptic feedback.
