Body fat analyzer with integral analog measurement electrodes

A biometric data acquisition assembly, comprising:

• a. a substrate;
• b. at least two conductive-film electrodes, each having an impedance, formed from a conductive material integrated on said substrate and capable of contacting an object having a biometric electrical characteristic to be measured;
• c. a biometric data acquisition circuit electrically connected to said electrodes and configured to measure a biometric electrical characteristic of the object via said conductive-film electrodes;
• d. an internal calibration impedance that corrects for the impedances of the electrodes electrically connected to the biometric data acquisition circuit to enable correcting the biometric electrical characteristic value such that it is independent of the impedance of the electrodes;
• e. a heating element formed by one or more of said electrodes in contact with said substrate;
• and
• f. a current source electrically connected to said heating element such that current may flow through it;
• whereby the current supplied by said current source causes said heating element to warm said substrate.
