Self-deployable current sources fabricated from edible materials

Self-deployable current sources fabricated from edible materials – Journal of Materials Chemistry B (RSC Publishing).

He browsed the books like a giant looking for something to read. Some were small enough to fit into a fold of his hand. Many of the books were illegibly small, and he didn’t know what they were all about. But reading them was never the point.

Neale Albert, 75, is a collector of miniature books, and he may be the most serious collector living in New York. By definition, miniature books are properly printed and bound, and for the most part no larger than three inches. Mr. Albert has over 4,000 of them, some the size of matchboxes and others smaller than a tab of chewing gum. Some of the books are worth many thousands of dollars.

  1. the quote for this entry didn’t come from the cited article but something else.

  2. Wrong quote, guys! :-P

    Flexible biodegradable electronics have the potential to serve as the centerpiece for temporary electronically active medical implants. Biodegradable electronics may exhibit many advantages over traditional chronic implants. Two important long-term goals for biodegradable electronics are (1) supplying sufficient power and (2) reducing the invasiveness of device deployment. Edible electronic devices are capable of addressing both challenges. Here, we introduce electrochemical electronic power sources that are compatible with non-invasive deployment strategies and are composed entirely of edible materials and naturally occurring precursors that are consumed in common diets. The current sources developed herein are powered by onboard sodium ion electrochemical cells. Potentials up to 0.6 V and currents in the range of 5–20 μA can be generated routinely. These devices could serve as an enabling platform technology for edible electronics used in non-invasive sensing and stimulation of tissues within the human body.
