　　Landsdowne Labs develops new material to make swallowing button batteries no longer scary

　　A material developed by startup Landsdowne Labs could make eating batteries less dangerous. This material takes advantage of the quantum tunnel penetration effect, and its main component is semiconductor silicon. When the battery is coated with this material, it will become a conductor only when it is subjected to greater pressure, and it can be energized, such as when it is installed in the battery box and pressed by the contacts; Pressure, this button battery is no different from a button.

　　An 8-month-old Minhou baby girl Xiaoyun (pseudonym) accidentally swallowed a button battery, which remained in her stomach for 5 hours. The doctor helped her take it out overnight, but the lye in the battery had leaked and burned the gastric mucosa much place. Lin Weidong, director of the Department of Gastroenterology at Fuzhou Children's Hospital, said that recently, the hospital often receives cases of young children swallowing foreign objects. Parents should strengthen supervision, keep children away from dangerous objects, and seek medical treatment in time after an accident.

　　A 4-year-old boy swallowed a battery and his life was hanging by a thread. Fortunately, the doctor took out the corroding battery in time. A 4-year-old boy in Torch Development Zone, Zhongshan City, Guangdong Province almost died after eating a button battery by mistake. The button battery was only the size of a fingernail. Why is it life-threatening if swallowed? According to Liu Zhishang, deputy chief physician of the Department of Gastroenterology at Zhongshan People's Hospital, the swallowed battery will change its position as the body changes...

　　It is a common parenting problem for children to eat something that cannot be eaten by mistake. It is even more dangerous if they eat a small button battery. A new material that is being prepared for commercial use may change this situation.

　　A material developed by startup Landsdowne Labs could make eating batteries less dangerous. This material takes advantage of the quantum tunnel penetration effect, and its main component is semiconductor silicon.

　　Button batteries are generally smaller in size and are commonly used in children's products. When this kind of metal battery is eaten into the human body, because the wet mucous membrane in the digestive tract is in contact with the battery electrode, a current discharge will occur, and the button battery will have a certain electrolysis effect on the body fluid, and the pH value near the negative electrode of the battery will change to alkaline, resulting in acute mucous membrane damage. It is more dangerous for children.

　　Studies have found that solid substances swallowed by humans generally enter the digestive tract quickly and are excreted within a few hours, such as coins. However, if it happens to be stuck in the esophagus, the coin or button will not bring any real danger, and it will still be discharged after waiting for a while, but the button battery will be attached to the digestive tract, which will cause damage to the mucous membrane or even perforation within a few hours, endangering the digestive tract.
