lightweight, superportable, and sustainable
power sources has become an urgent need for most modern personal electronics.
Here, we report a cut-paper-based self-charging power unit (PC-SCPU)
that is capable of simultaneously harvesting and storing energy from
body movement by combining a paper-based triboelectric nanogenerator
(TENG) and a supercapacitor (SC), respectively. Utilizing the paper
as the substrate with an assembled cut-paper architecture, an ultralight
rhombic-shaped TENG is achieved with highly specific mass/volume charge
output (82 nC g–1/75 nC cm–3)
compared with the traditional acrylic-based TENG (5.7 nC g–1/5.8 nC cm–3), which can effectively charge the
SC (∼1 mF) to ∼1 V in minutes. This wallet-contained
PC-SCPU is then demonstrated as a sustainable power source for driving
wearable and portable electronic devices such as a wireless remote
control, electric watch, or temperature sensor. This study presents
a potential paper-based portable SCPU for practical and medical applications.
