In this paper, a manual dispenser printing-based fabrication technique has been developed to synthesize a flexible thermoelectric generator (FTEG). Fabricated FTEGs, printed on polyester fiber clothe, convert the thermal energy from the human body into electrical energy using the Seebeck effect. Two flexible prototypes (prototype A and prototype B) were fabricated using a manual dispenser printing technique with n-type (0.98Bi,0.02Sb)₂(0.9Te,0.1Se)₃ and p-type (0.25Bi,0.75Sb)₂(0.95Te,0.05Se)₃ thermoelectric (TE) materials. The fabricated prototypes consisted of 12 pairs of n-type and p-type legs connected by silver conductive threads. The experimental investigations were conducted to determine the characteristics and the electrical outputs of the fabricated prototypes. The open circuit voltage and power output of prototype A and prototype B were 22.1 mV and 2.21 nW, and 23.9 mV and 3.107 nW …
