We integrate grating-structured PTENGs into a book as a self-powered anti-theft sensor, which can effectively convert mechanical triggering agitated during handling the book pages into an electric output to either drive a commercial electronic device or trigger a warning buzzer. Furthermore, different grating-structures on each page produce different number of output peaks which can accurately position the turned pages and record the pages flipped over.

Now a sensor network is technology towards miniaturization, portability and usually integrated by several different functional functionality in the recent years [1-3], sensor sensors and many small electronic devices. A network has been a powerful driving force for the practical challenge for portable sensor network is next phase of information technology. More and the huge number of batteries used in the system, more types of sensors have been widely used in Address correspondence to [email protected] 2 Nano Res. which needs to be recharged, replaced, monitored trigger a warning buzzer. Furthermore, different and maintained. This will cause not only a grating-structures on each page produce different horrendous task but also environmental and health number of output peaks, which can accurately concerns. A self-powered system aiming at position the turned pages and record the pages harvesting energy from the environment [8-11] to flipped over. This work provides a potential power sensor networks is proposed to offset or even method to develop the self-powered, durable, cost replace the reliance of small portable electronics on effective anti-theft system for books, paintings and batteries [2, 12, 13], which will make great any other flexible materials in the future. contribution to the whole environment in the next few decades. So far, portable and renewable human 2 Experimental section motion-driven self-powered systems have been scavenged with diverse approaches based on 2.1 Fabrication of the PTENG piezoelectrics [14-17], electrostatics [18, 19], and electromagnetics [20, 21].

In this paper, we demonstrate a new anti-theft sensor based on the PTENG type of paper-based triboelectric nanogenerator (PTENG) using indium tin oxide (ITO) film and Grating-structured PTENGs were applied into polyethylene terephthalate (PET) film as each page of a book to form a self-powered triboelectric surfaces and it can be made in a book anti-theft sensor. The grating-structured PTENGs or any other paper products to harvest kinetic were made on the adjacent pages, as shown in energy when the papers contact, bend or relatively Figure 4a. The one-grating-structures were adhered slide with the advantages of both transparent and on the even pages, and the multi-grating-structures flexible.
