Researchers will be helping to search e-dogs because of the sharp scent of identifying objects.

Especially in the aftermath of the earthquake-relief rescue, the intense scent of the dog became very helpful to understand the presence of people stuck under the debris. But sometimes the post-disaster situation is such that it is difficult to take a blood-meat dog on the spot. In this situation, scientists have presented electronic dogs for rescue workers. This e-dog is nothing but a sensor capable of identifying smell. Researchers say the use of small and low-cost sensors in the form of this sensor can now be done very easily.
