1. Apparatus comprising:
- an article of clothing configured to overlie first and second relatively moveable portions of a human body so as to move in conformance with relative movement of said first and second relatively moveable body portions;
a piezoelectric transducer coupled to said article of clothing so as to undergo a deflection in response to said relative movement of said body portions and to generate a voltage signal proportional to the magnitude of said deflection; and
an electrical component configured to apply a resistance to said voltage signal such that said transducer, having said resistance applied to said voltage signal, dissipates the kinetic energy of said relative movement and thus restrains said relative body movement of said body portions.

Abstract
An article of clothing including a piezoelectric transducer and an electrical component restrains movement of a first body portion relative to a second body portion. The article of clothing can be a sports bra that controls the wearer'"'"'s breast movement relative to the wearer'"'"'s torso. As the breast moves, the piezoelectric transducer deforms and induces a voltage that is passed to the electrical component. The electrical component provides either a resistance or a control signal to the transducer. The transducer stiffens in response to the electrical component and reduces the movement of the breast by placing an external force on the breast.
