摘要：
A magnetic tracking tag for animals may detect the occurrence of a predation event. The tag may include a pH sensitive material that degrades in the environment of a predators gut. The degradation of the pH sensitive material causes a change in a detectable magnetic field of the tag, which allows the tag to detect the predation event and adjust its operation accordingly.
