Abstract
A system for tracking the laboratory animal position and movement in a walled enclosure or cage for observation and evaluation is disclosed. The system consists of a plate placed on the bottom of the cage whereon multiple electrodes are configured as column-row two-dimensional electrode array, an electronic circuit detecting and measuring the capacitance between said electrodes, and a microprocessor determining the animal's location. The electronic circuit repeatedly measures the capacitance between the electrodes in a sequential manner. The animal's location and movement is determined by detecting the changes in capacitance on said plate.
