Fig.1 Schematic diagram of flexible thermoelectric devices for human body surface waste heat harvest and conversion
In view of the current energy supply and energy storage problems of flexible wearable electronic devices, our group focuses on the preparation and construction of low dimensional nano inorganic/organic and composite thermoelectric materials and devices by chemical synthesis and physical deposition, besides the waste heat harvest performance from the human body. Meanwhile, we commit to prepare long fiber biomass-based derived carbon materials based on specific chemical activation methods and assemble into flexible supercapacitors, investigate the structure-property relationship between material structure and capacitance performance. In addition, our research group also expanded the wide application of thermoelectric materials in the field of photoelectrocatalysis and photodetection. The specific work is as follows:
Controlled preparation of one-dimensional Tellurium based nanowires, nanotubes and vertical nanowire arrays and its application in flexible thermoelectric devices;
Study on thermoelectric properties for Polyselenophene-based organic, organic/inorganic composite thermoelectric material prepared by electrochemical method;
Preparation of coconut silk, saussa straw and other long fibrous plant-based porous carbon material and its application in flexible supercapacitor electrode material;
Constructing a thermoelectric photodetector with enhanced plasmon resonance effect by noble metal nanoparticles;
Constructing a self-sustaining photoelectrocatalytic system powered by BiTe-based thermoelectric materials.
