by Lori Dorn from Laughing Squid on (#1M43Q)
Japanese studio Kyouei Design has created an absolutely brilliant bookmark made with a special conductive nano-particle ink that lights up embedded LEDs when the ends are pinched together with the simple addition of a coin-sized lithium watch battery.
(translated)'bookmark light' is a bookmark which is printed on a special film using the ink which transmits electricity. It can use as a bookmark, also can be used as illumination to use a lithium coin battery.
