Nendo transforms electronic paper to rollable and adjustable flashlight

paper-torch
Flashlights tha t have been designed using the technology of AgIC, that prints electronic circuit boards onto paper, films an d cloth using silver particle ink.

After testing various types of paper, we selected YUPO paper by Takeo that is used in ballot paper for elections. With YUPO paper, ink sits evenly and the smooth surface ensures the ink and paper can be rounded with minimal force, and are less likely to curl.

The paper is also hard-wearing, water resistant and therefore also suitable for industrial applications.

The circuits on both sides of the paper were printed with a checker pattern, and two button cells and seven LEDs were glued on with conductive adhesive. The resistance was changed by varying the path length of each #led by adjusting how tight you roll the paper, enabling the lighting to be co ntrolled. The longer the path the higher the resistance, conversely the shorter the path the lower the resistance.
