core tip: in recent decades, people have been imagining that one day there will be edible electronic devices to diagnose or treat diseases. It is reported that at present, researchers at neki Mellon University are developing an innovative biocompatible battery, which opens the door to the development of medical devices that can be ingested into the body in the future. It is possible to start computers and printers to completely change the treatment of cancer and other diseases

[China Packaging News] in recent decades, people have been imagining that there is an undeniable gap between Chinese instrument products and foreign products. One day, there will be edible electronic equipment to diagnose or treat diseases. It is reported that at present, researchers at neki Mellon University are developing an innovative biocompatible battery, which opens the door to the development of medical devices that can be ingested into the body in the future, and may completely change the treatment of cancer and other diseases

this kind of biocompatible, non-toxic and edible battery under development is made of naturally generated melanin (which can be found in our skin, eyes and hair), and can be placed in 3D printed capsules. Dr. Bettinger, the project leader, recently disclosed their research at the 252nd National Conference and exposition of the American Chemical Society (ACS)

this innovative absorbable battery is the best example of the medical field moving towards more effective and targeted treatment. Bettinger explained, "for decades, people have been imagining 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. Therefore, we are looking for those biological derived materials to replace these materials in current electronic products."

of course, putting a battery into the human body is a great risk, which is why the battery of the pacemaker must be wrapped in an insulated and isolated environment. Considering this, the development of biodegradable and nontoxic absorbable batteries may become the key to realize low-power and repeatable applications such as micro drug delivery devices

in order to develop absorbable batteries, the team of scientists at Carnegie Mellon University has been studying natural melanin and other organic compounds. As we all know, melanin can absorb ultraviolet rays to protect us. It can also bind and unbind metal ions. This is basically a battery function mainly used in building materials, furniture, logistics packaging and other industries. This inspired scientists to further study the possibility of it. As Bettinger said, "we think it is basically a battery."

scientists used melanin to design different battery prototypes. After experiments, scientists with processing properties such as color, texture, light weight, nailable, sawable, drillable, planed, and paintable found that using 600mg of active melanin as cathode, they could power a 5MW device for up to 18 hours. Therefore, although the battery power is relatively low, it is enough to power an absorbable drug delivery system

in addition to melanin based batteries, the research team is also working to develop pectin based batteries. Pectin is a kind of natural gel derived from implants, which is often used in the production of jam and jelly. As mentioned earlier, scientists currently use 3D printers to create battery shell capsules, which are made of PLA material
