By effectively converting waste heat into electricity, thermoelectric materials and devices can provide an alternative approach to tackle the energy crisis. Amongst materials, bismuth telluride (Bi2Te3) its derivatives exhibit high figure of merit ZT values in near-room-temperature region show great potential for application devices. Considering rapid development Bi2Te3-based their last few years, a short systematic review is much needed. Here, we summarize novel designs, properties, applications different contexts, including wearable, portable, implantable, cross-disciplinary applications. The challenges outlook are also considered. This work will guide future that target broader more practical
