1. An apparatus for sensing a change in motion proximate to a body part of a person, the apparatus comprising:

  • a flexible substrate to substantially conform to a surface of the body part so as to facilitate comfortable and safe intimate proximity of the apparatus to the body part;

    at least one sensing element disposed on the flexible substrate to sense the change in motion proximate to the body part and provide at least one output signal representing the sensed change in motion;

    a power source to provide power to the at least one sensing element; and

    switching circuitry, coupled to the power source and the at least one sensing element, to detect the proximity of the apparatus to the body part and to electrically couple and/or decouple the power source and the at least one sensing element based at least in part on the detected proximity of the apparatus to the body part.
