Sub-research directions include
(1) Synthesis and characterization of emerging energy materials
(2) Fabrication and characterization of self-powered sensors (e.g. pressure/strain sensors, photosensors etc.)
(3) Fabrication and characterization of environmental energy harvesters (e.g. nanogenerators, photovoltaics etc.)
(4) Exploration of new concept and phenomenon in self-powered devices and energy harvesters
