 <p><strong>Bacteria batteries!!! I have to look deeper into this and how they have made so many various forms of batteries. Energy is a major crux of our future and the more types of storage and generation we have the better.&nbsp;</strong></p><p>&nbsp;</p><blockquote><p>Papertronics can be particularly useful in remote areas with limited resources because they're powered by bacteria that can inhabit even the most extreme of conditions and break down nearly any material to produce electrons. They don't need a well-established power grid, either. In addition, though paper batteries are designed to be disposable after they're used, their materials are recyclable – and new batteries can be created from recycled paper.</p><p>&nbsp;</p><p>As revolutionary as paper-based bio-batteries are for future electronic devices, they're fairly straightforward to make. The polymers and <a href="https://phys.org/tags/bacteria/">bacteria</a> can be blended with paper in traditional manufacturing processes, including roll-to-roll printing and <a href="https://doi.org/10.1039/C4RA04946B">screen printing</a> – or even be painted or poured right onto paper.</p><p>&nbsp;</p><p>Other materials can also be added to the paper batteries – like metals, semiconductors, insulators and nanoparticles. These and other substances can add more properties and capabilities to paper-based devices, opening new doors for the next generation of electronics.</p></blockquote><p><strong>In one of the article authors other papers they state that they have a Saliva activated battery...</strong></p><blockquote><p>This work creates a low‐cost, disposable, long shelf life and eco‐friendly micropower source that can be easily integrated in paper‐based POC devices and be readily activated by one drop of saliva, which is readily available in any challenging area.</p></blockquote><p><strong>WHAT?!?!?! This is why I need to dig deeper on this subject as the advancements happening are pretty incredible. The potential for essentially living batteries is quite astounding and could turn everything around us into potential power generators or storage.</strong></p>
