热电发电机和压电发电机由于从热和机械振动中产生电能以替代市售可再充电电池而引起了相当大的关注。在这份报告中，我们通过简单的化学溶液方法将压电纳米发电机（PVDF-ZnO）和热电发电机（分别由Bi 2 Te 3-RGO（还原氧化石墨烯）和Sb 2 Te 3-RGO制成的n腿和p腿）结合在一起，制备了柔性混合器件。这项研究的重点是将热电和压电集成在一个小的柔性设备中，以从热能和机械能中获取电能。在温差为4K时，温差发电器的输出功率约为1.8nW，压电发电器的输出功率约为1.2 μ W。
Thermoelectric and piezoelectric generators have drawn considerable attention for generating electrical energy from heat and mechanical vibrations for replacing the commercially available rechargeable batteries. In this report, we have fabricated flexible hybrid device by combining of the piezoelectric nanogenerator (PVDF-ZnO) and thermoelectric generator (n-leg and p-leg made of Bi2Te3-RGO (Reduced Graphene Oxide) and Sb2Te3-RGO, respectively) by simple chemical solution method. The focus of this research is to integrate thermoelectric and piezoelectric in a small flexible device to harvest electrical energy from both thermal and mechanical energies. The output power of thermoelectric generator is similar to 1.8 nW at a temperature difference of 4 K and the output power of piezoelectric generator is similar to 1.2 mu W.
