Could RFID Track the Positions of Mice?

Posted By RFID Journal, 02.02.2016

Our lab is trying to establish an experimental setup for a mouse that is basically a large area measuring 30 centimeters by 30 centimeters (11.8 inches by 11.8 inches). We would like to track mouse's movements and positions via injected passive tags. Would it be possible to obtain an accurate position for the mouse to the centimeter level?




It is possible. You would need to find or create passive low-frequency (LF) antennas measuring 1 centimeter by 1 centimeter (0.4 inch by 0.4 inch). As the mouse moves around, its tag would be picked up by the antenna underneath it. By mapping the antenna ID to the grid, you would be able to plot the mouse's movements.

In 2011, we wrote about a University of Wurzburg Ph.D. candidate named Mario Pahl, who was tracking bees (see RFID Helps Scientists Study Honeybees' Homing Behavior). He glued a mic3-TAG passive 13.56 MHz tag, complying with the ISO 15693 and 14443 standards, to the back of each bee. The tags measured 1 millimeter by 1.6 millimeters (0.04 inch to 0.06 inch). Each tag stored a unique 64-bit number. You could use the same tags on mice and create the same type of antenna grid as described above. I raise this option since it might be easier than injecting LF transponders inside ampoules into the mice.

Hi Mark, Thanks a lot for your advice. My original plan is also dividing our cage into grids and track mouse's positions. However, if I have 1cm by 1cm antennas, there would be 30 antennas beneath our area. Since our area might be enlarged in future, these many antennas might be cumbersome. Now I am thinking of using common methods, like triangulation or multilateration. Say I only use three or four readers, is it possible to achieve centimeter level resolution with these methods? Also do you have any recommendations for the frequency range? LF, HF or UHF? Thanks a lot, Chris.
