In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a transmission medium such as air or water. In physiology and psychology, sound is the reception of such waves and their perception by the brain. Humans can hear sound waves with frequencies between about 20 Hz and 20 kHz. Sound above 20 kHz is ultrasound and below 20 Hz is infrasound.

Sharing an introduction on papermaking with paper, fabric rags and plants, we propose to develop “eCotton-paper” by integrating conductive and light emitting elements in between the paper sheet, during the making process. Once your “eCotton-Paper” will be up and running you will be able to program it through Arduino to make beautiful patterns and lighting effects!
