FWIW, it's biodegradable but it doesn't dissolve in water. If you've never handled a kombucha scoby, it's very rubbery and tough.

I've held it, but i've also got it wet (after being dry), and i seriously doubt that the printed-on metalic layer would survive, since the surface gets soft and jelloey.

A scoby is just basically a matrix of cellulose. Assuming the circuits are printed into that substrate it could be quite stable
