The engineering principles behind electronic books that replicate the “ink on paper” aesthetic have existed for centuries. The idea is simple: clay particles suspended in water disperse when a constant electric field is applied to the fluid.
In the 1990s, engineers at MIT discovered a way to keep the particles from clumping together. Using small capsules or balloons filled with viscous liquid and particles allows the particles to move within a very specific amount of space.
In 2004, Royal Philips Electronics released the first eBook reader with an electronic display: the Sony Librie. The new device looked like newsprint and was perfect for everyday use – even in direct sunlight. Even better, the device was also bi-stable; if you didn’t change the image, the device didn’t use any power.
