报告摘要:

The triboelectricity of the human body: energy harvesting, motion sensing and signal transmitting

Contact electrification, which is also namely triboelectrification, is a common phenomenon that happens when two materials with different charge affinities get contact physically. Such process happens on human body also because human skin is a good triboelectric material and has a high affinity to positive charges. When the human skin get contact with materials like textiles, positive charges are generated on the body. If we construct a circuit that can let the charges flow, electricity is obtained. That said, the mechanical energy of the physical contact between the skin and the textile has been converted to electricity. We can design and modify materials with chemical and physical method to increase the contact electrification to boost the energy output. We have proved that the power output of a human body based triboelectric nanogenerator (H-TENG) can reach 30 W/m2. Further studies have also demonstrated that the H-TENG can also been used to sense body motions and transmit electrical and optical signals.
