3.3: Fabricating Self‐Powered E‐paper on Paper Substrates and Driven by Triboelectric Nanogenerator Module.

The electronic paper (E‐paper) has the advantages of low power consumption, flexibility, small form factor, and eye‐friendliness. However, most E‐paper substrates are made by indium tin oxide (ITO) glasses or plastic substrates, which are hard to degrade in the natural environment. Our previous work introduced a self‐powered E‐paper (SPEP) integrated with triboelectric nanogenerator (TENG). Here, a paper‐based SPEP was further demonstrated, driven by a TENG module without any other power module. By combining the self‐powered driving mode and paper substrates, this work showed novel possibilities for E‐paper devices, which provided great potential in future Internet of things (IoT) displays.
