Implantable Devices [PDF]

Berkeley Scientific Journal, 2009
In science fiction, humans have conjured up numerous possibilities of semi-robotic, semi-humanoid beings: cyborgs, which are fictional beings that are part human, part robot; androids, or robots that look like and behave like human beings; automatons, which are humans who behave like machines; and bionic beings, or humans with organs or functions ...

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

Advanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.
