Battery with added human blood

Argentine scientists have created the first battery prototype using human blood hemoglobin as a catalyst for an electrochemical reaction.

Hemoglobin is a protein found in red blood cells. It is responsible for transporting oxygen from the lungs to various tissues of the body and transporting carbon dioxide in the opposite direction.

The research team has developed a harmless zinc-air battery that uses a blood substance to speed up the oxygen reduction reaction. During the reaction, oxygen turns into water and releases electrons.

In the experiment, a prototype device with 0.165 milligrams of hemoglobin worked for 20-30 days. These batteries are more resistant to harsh environmental conditions and are biocompatible, allowing them to be safely used in pacemakers and other body-worn devices.

Scientists say that in the future hemoglobin for batteries can be obtained from the blood of any mammal. So far, the main disadvantage of the invention is the inability to charge such batteries.
