Papercraft-tronics?
As crazy as it may sound, the power needed to supply the millions of IoT wearable devices that seem set to invade our lives could come from sheets of folded material or origami springs. Scientists from universities in the US, Taiwan, Saudi Arabia, and China have been developing a foldable, stretchable, triboelectric generator based solely on paper, aluminum foil and Teflon. The static electricity generated by movement of the paper over the polymer is conducted to the circuit via aluminum and copper wires. The first prototype produced enough power to light 4 LEDs simultaneously. That’s it, easy as pie! Aside from working as a power source, they can also be used as pressure sensors, providing a voltage proportional to the weight applied to the structure.
In electronics, anything low power, low cost, and lightweight is more than welcome. So if you ever enjoyed cut and paste activities at school (no, we don’t mean Ctrl+X and Ctrl+V), you can have a go at building your own generator too.
ДВА! В России создана отраслевая организация для объединения и защиты интересов всех авиамоделистов и пользователей дронов. Организация получила название «Всероссийская Ассоциация Малых Беспилотных Летательных Аппаратов», сокращенно АМБ.
