Mechanism of suspended animation and potential device applications

The state of suspended animation refers to any living being or person that has been classified by the medical system as showing no signs of life. The body is often dramatically revived after several hours or days. Sometimes, a medically certified individual can be revived, especially in cases of electric shock or heart attack [1]. This article aims to understand how the human body can restart life in a state of suspended animation, focusing on the activation mechanisms before and after regaining consciousness. More importantly, it seeks to prevent premature judgments that could lead to unnecessary death, as in the case of those in suspended animation, and to avoid tragedies at places like Song Jun Crematorium.
