Wearable body-fat sensor

An apparatus for detecting a body-fat composition of a person, comprising:

• a pair of shoes having a weight sensor;
• a wearable body structure, of flexible material, having an inner surface;
• a flexible electrical conductor affixed to said inner surface, said conductor having a first-end portion and a second-end portion;
• an impedance-measuring circuit having at least one pair of electrodes, said pairs of electrodes being electrically coupled to said first end of said electrical conductor and said second end of said electrical conductor;
• a memory for storing data, which includes height, age, and sex of said person;
• and, a controller for processing data received from said weight sensor, said impedance-measuring circuit, and said memory to determine the body-fat composition of said person.

A method for measuring the body-fat composition of a person, the method comprising the steps of:

• (a) inputting height, sex, and age of said person to a controller;
• (b) standing on a pair of shoes having a weight-measuring sensor to measure the weight of said person and to contact a right sole and a left sole on a pair of electrodes;
• (c) providing an electrical path between said pairs of electrodes;
• (d) detecting a voltage difference between said pair of electrodes to measure an impedance by means of an impedance-measuring circuit;
• and,
• (e) calculating a body-fat percentage by means of said controller.
