Does a dead person's fingerprint work? Can a person's fingerprint activate the phone's fingerprint sensor even after his death?

Have you ever had this question in your mind that if we use the fingerprint of a dead person to activate the phone's fingerprint sensor, then what would happen, will it work or not? So obviously for this, you just have to understand the working of the mobile, when this new generation advanced mobile was first launched in the mobile market, it started becoming famous as screen touch mobile or touch screen mobile in India. Actually this screen touch mobile and what we now call as smartphone, generally works with electrical charge present in our hand. 

The fact is that all this is possible because of the presence of electricity in our body, due to which we are alive, that is, energy is present everywhere in the human body like skin, hand or finger, by which the mobile is able to work by reading its electric charge. It reads your fingerprint, and when you scroll the mobile screen with your hand, the screen receives electrical signals from the body and helps the mobile run smoothly. The electrical impulse occurs in the body only as long as the person is alive, then what kind of conclusion do we get from this entire explanation.

So yes, in reality, the fingerprint won't work if a person dies, but then the question is, will it work if someone faints. So with the same logic, you should understand that if someone is unconscious or faint, there is still an electrical impulse in his body because the person is not dead yet. When a person becomes unconscious his consciousness is gone only, all other activities like blood flow, the heart are still functioning properly. So in this case fingerprint will work but now another question arises whether fingerprint will work in a Coma or not.

So the answer is yes, as long as a person is alive, his heart is working and blood is running in his body, even though he is in a coma, his fingerprints will still work as the electrical charge is still present in his body. When someone dies, only then that electrical charge becomes absolutely zero, making it impossible to unlock the phone's fingerprint sensor.
