Abstract
There is provided a system and method for harvesting electrical energy from interaction with papers. The system comprising an electret disposed between a first electrode and a second electrode, and an interactive device connected to one end of the first electrode and one end of the second electrode to provide an electrical potential, the interactive device configured to receive the electrical potential by moving the second electrode relative to the electret for generating electrical energy. Interactive devices that can be activated by the generator can include a light-emitting diode, an electronic paper display, an infrared communication, and a buzzer.
