I. Functionalized dielectrics-based triboelectric nanogenerators
I. Functionalized dielectrics-based triboelectric nanogenerators
Triboelectric nanogenerators convert mechanical motion into electricity, and their output is largely governed by the charge density of the dielectric layer. This theme engineers the chemistry and structure of dielectric materials — tuning polarization and charge-trapping behavior — to raise surface charge density and, in turn, power output.

II. Self-powered sensor system
By harvesting ambient energy, a device can sense its surroundings without an external power source. This theme develops self-powered sensors that read environmental signals — such as humidity or motion — directly from the electrical output of the energy-harvesting element itself.

III. Moisture-driven energy generator
III. Moisture-driven energy generator
Moisture-driven energy generators (MEGs) produce electricity from the interaction between water molecules and hydrophilic materials, enabling continuous power in ambient humidity without a water reservoir. This theme designs film-type and free-standing MEGs — for example, based on hydrophilic aerogel/hydrogel structures — that operate stably across a wide humidity range.
