My first question was "but why?" and apparently it has more applications than one would think at first, as it says in the article: edible batteries in toys for kids would eliminate toxicity risk and supporting electronics that go inside our body (they are working in edible transistors).

I also wanted to highlight this hilarious phrase in the article:

> While all of these components are nontoxic and edible, the researchers clarify that a user is not supposed to eat the battery on purpose, which would obviate the whole point of making it rechargeable.

Now we need edible electronics and webcams, so you can eat a webcam - make photos inside, send them out of body - and... digest it...

We have edible, but not digestible wireless cameras already. Prepare for a slightly different noise when using the bathroom in the next few days/hours though.

That’s genius. Now I want to get one just out of curiosity. Looking at the cost though, I think I’m going to have to pass this one

... just to clarify, when you say pass ...

Kind of already a thing although you have to pass this:

Another high value use might be long term surgical instruments that are meant to be left in the body for several weeks before degrading harmlessly. Imagine something like dissolving stitches.
Re:Researchers craft a fully edible battery by LoganDark on Thursday May 11, 2023 @04:36PM (#35908043)
Don't dissolving stitches already exist[0]?

Yes. Now imagine e.g. dissolving pace makers or whatnot.
Re:Researchers craft a fully edible battery by LoganDark on Friday May 12, 2023 @06:30AM (#35914301)
I wonder what use that would have—maybe healing after heart surgery? Using a pacemaker as a crutch until your heart can beat on its own again?
Re:Researchers craft a fully edible battery by Doxin on Friday May 12, 2023 @09:49AM (#35916248)
a pacemaker is admittedly a poor example, but it's also just that: an example. I'm sure there's hosts of medical devices that would benefit from dissolving. Perhaps even devices that are infeasible currently because they don't dissolve.

Here and I was going to suggest they add a graham cracker crust.

So much potential, which will be left unused...

Potential as in electric potential? :)

I associate this style with soulless marketing campaigns. Thanks, marketing, for destroying language for me.

That was my intention - glad it worked!
Re:Researchers craft a fully edible battery by xutopia on Thursday May 11, 2023 @10:55AM (#35903092)
Or just coat the batteries in disgusting taste so kids don't put them in their mouth repeatedly.

This is a good idea, much like the usage of Bitrex in certain household items, mainly cleaning solutions.
