Abstract
This invention discloses an abnormal cell detecting device having at least a pair of electrodes to be attached to a portion of a body. At least one electrode of the pair of electrodes is constituted by a plurality of independent electrodes cells. One voltage at a frequency is applied between the pair of electrodes, and another voltage of a different frequency is applied between them. As a result, electrostatic capacitances corresponding to the two frequencies are measured between the electrodes as voltages by a capacitance measuring unit. The ratio of the voltages is calculated by a division unit, and the resultant ratio is digitally sent out through an A/D converter to a memory unit. Digital signals corresponding to a plurality of electrode cells are stored as image data in the memory unit. A display unit displays the position and size of abnormal cells, based on the image data of the memory unit.
