Researchers at Carnegie Mellon University are developing an innovative biocompatible battery that opens the door to future medical devices that can be ingested in the body and potentially revolutionize the treatment of diseases such as cancer. It is understood that this biocompatible, non-toxic, edible battery is being developed using naturally occurring melanin (which can be found in our skin, eyes and hair) and can be Place it in a 3D printed capsule. The project's head, Dr. Christopher Bettinger, recently revealed their research at the 252th National Conference and Expo of the American Chemical Society (ACS).
This innovative, absorbable battery is one of the best examples of the medical field moving towards more effective and targeted treatments. Bettinger explained: "For decades, people have been thinking that one day we will have edible electronic devices to diagnose or treat diseases. But if you want to take a "device" every day, you must consider the toxicity problem. So look for those bio-derived materials to replace these materials in current electronics."
Of course, putting a battery into the human body is a big risk, which is why the battery of the pacemaker must be wrapped in an insulated, isolated environment. With this in mind, the development of biodegradable, non-toxic, absorbable cells is likely to be key to achieving low power, repeatable applications such as micro drug delivery devices.
In order to develop absorbable batteries, the team of scientists at Carnegie Mellon University has been researching natural melanin and other organic compounds. It is well known that melanin can absorb ultraviolet rays to protect us. In fact, what you don't know is that it can also bind and unbind metal ions, which is basically a battery function! This inspired scientists to delve deeper into its possibilities, as Bettinger said: "We thought it was basically a battery."
