A system for reading transponders may include a printed circuit board and an electrotextile antenna. The tool collar includes a through bore and is disposed to be operatively coupled with a drill string such that each sample tank may receive a correspondingly preselected formation fluid sample without removing the drill string from a well bore. Propagation paths are computed using a far-field approximation technique for Maxwell’s equations. A first data transfer circuit is connected between the first and third data storage units. The third active material exhibits charging and discharging capacity below a corrosion potential of the current collector of the negative electrode and above a decomposition potential of the first active material.
