Figure 1. (A) Schematic diagram showing the pattern deposition by screen printing. Reproduced with permission^[75]; (B) Screen-printed radial structured TEG with n-type Bi₂Te_2.7Se_0.3 and p-type Bi_0.5Sb_1.5Te₃ on polyimide substrates. Reproduced with permission^[76]; (C) Screen-printed TEG on flexible glass fabric substrate and the voltage generated using human body heat^[54]; (D) Fabrication process for the screen-printed flexible thermoelectric films. Measured output (E) voltage and (F) power of the thermoelectric device as a function of current. Reproduced with permission^[57]. TEG: Thermoelectric generator.
