<p>The black dot in the TEM images is an artifact for imaging.</p
Schematic picture of the growth of gold nanobelts.
<p>(A) the beginning of a belt, (B) the density change of nanoparticles on the belt, (C) the formation of a new pinning site, (D) the next belt starts to grow. <i>j<sub>e</sub></i> is the evaporation of water on the wetting film, <i>j<sub>p</sub></i> and <i>j<sub>w</sub></i> are the gold nanoparticles and water influx towards the meniscus driven by evaporation induced capillary force, <i>f<sub>c</sub></i> is the capillary force that drives the nanoparticle to assemble, <i>f<sub>f</sub></i> is the force which drags the nanoparticle down to the bulk solution that is generated by the convection flux.</p

Human Body Constituted Triboelectric Nanogenerators as Energy Harvesters, Code Transmitters, and Motion Sensors
Human skin is a dielectric
material that can be used as a triboelectric material for harvesting
energy from body motions. The output power of such a human skin-based
triboelectric nanogenerator (TENG) is relatively low. Here, we assembled
high-output human body constituted TENGs (H-TENGs) by taking advantage
of the unique electrical properties of the human body, such as high
skin impedance, low tissue resistance, body capacitance, and conductivity.
The output of a H-TENG can reach 30 W/m<sup>2</sup>, which is enough
to drive small electronic devices, such as a timer or a calculator.
The unique feature of the H-TENG is that it can perform the four fundamental
modes of TENGs, which has not been reported elsewhere. Such a feature
allows the H-TENG to act as a code transmitter to send light and electrical
signals, such as Morse code. H-TENGs also benefit the development
of high-performance, self-powered body motion sensors. Our findings
suggest new strategies for harvesting energy from human body motions,
as well as new types of motion sensors and signal senders
