We’re one step closer to biodegradable gadgets. These computer chips are made almost entirely out of wood. Scientists at the University of Wisconsin, Madison teamed up with the U.S. Department of Agriculture’s Forest Products Laboratory to fashion the new semiconductor chip. The paper was published today in Nature Communications.

See, most of a computer chip is composed of a “support” layer that cradles the actual chip. The research team replaced that support layer’s non-biodegradable material with something called cellulose nanofibril (CNF), which is flexible, wood-based, biodegradable—all things that can make a device way less hazardous.
