nendo's paper torch is an electronic paper that rolls itself up into a lamp

japanese designer nendo just unveiled his latest creation: an electronic paper that rolls itself up into a working torch. developed using AgIC’s flexible circuits in collaboration with TAKEO — a japanese paper distributor — ‘paper torch’ works by printing its electronic circuit boards onto paper, films and cloth using silver particle ink. the result is a minimalist lighting piece that can be used as a torch, and as pendant and desk lamps.

the paper torch by nendo has circuits on both sides of the paper that were printed with a checker pattern. two button cells and seven LEDs were glued on with conductive adhesive while the resistance was changed by varying the path length of each LED. this detail allows the user to control the lighting by how tight the paper is rolled. the longer the path, the higher the resistance; conversely, the shorter the earth the lower the resistance. this means that light becomes dimmer when you roll the lamp loosely, and brighter when it has been tightly rolled.

‘after testis various types of paper, we selected YUPO paper by TAKEO that is used in ballot paper for elections,’ says nendo. ‘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.’

users can also experience two different types of color temperature: warm and cold. this is possible thanks to the LEDs characteristics that change color while touching the paper. when the paper is wrapped with the surface adhered to the LED facing upwards, the light turns into a warm orange color. when the paper is rolled inside out, the light turns into a white color. furthermore, when pushed through a stand with rings attached to the end, it can also be used as a simple desk lamp. many different applications are possible in the near future such as emergency use and disaster prevention.
