Impedance tomography is the process of generating an electronic image           from the impedance characteristics of a body of matter.  This                   technique has been used successfully as a tactile sensor.  This                 reserach project is concerned with the creation of a high resolution,           two dimensional impedance imaging array capable of taking an                    electronic picture of a wall growing cell culture.  Fundamental to              this system is the two dimensional cross bow array.  While some                 progress has been made on this array, several significant problems              remain.  One such problem with the two dimensional cross bar array is           the determination of the localized impedance measurements at the                intersection points of the two grids which comprise the array.                  Initial efforts have indicated variations of impedance of only 5% to            10% change leading to poor localization.                                                                                                                        Research will be conducted to improve the measuring cell impedances             and to develop techniques to monitor the growth of cell colonies with           impedance measurements; electronics to scan an area of the cross bar            array; galvanostats needed in shielding the principal wires from                extraneous currents; fabrication of the cross bar arrays.
