The United States develops a new button battery that will not harm the body if eaten by mistake
The Massachusetts Institute of Technology, Brigham and Women's Hospital, and Massachusetts General Hospital jointly developed a QTC coating that is placed on the surface of the battery and only conducts electricity when the battery is under certain pressure. The research team calculated the pressure on the battery as the esophagus peristalized and pushed food, ultimately ensuring that the coating remained insulating within the esophagus.
Children are naturally curious, and there are often incidents of children eating button batteries by mistake on the Internet, and now the good news is that a new type of button battery has been developed in the United States, even if it is swallowed, it will not hurt the body.
The Massachusetts Institute of Technology, Brigham and Women's Hospital, and Massachusetts General Hospital jointly developed a QTC coating that is placed on the surface of the battery and only conducts electricity when the battery is under certain pressure. The research team calculated the pressure on the battery as the esophagus peristalized and pushed food, ultimately ensuring that the coating remained insulating within the esophagus.
Fortunately, this QTC (quantumtunnelingcomposite) has been widely used in many other products, such as keyboards and touchpads, etc., so adding it to the button battery does not increase much cost.
In addition to improving battery safety, the researchers say that because the material is waterproof, it is better suited for outdoor use than before, and they plan to test it on lithium-ion batteries.
