Summary: We have developed a method to fabricate thermoelectric devices on office paper substrates using handcrafting techniques. The devices consist of thin films of WS2, Te, and BP (P-type semiconductors) and TiS3 and TiS2 (N-type semiconductors) deposited by rubbing these materials' powders onto the paper. The semiconducting films exhibit high Seebeck coefficients, reaching (+1.32 +/- 0.27) mV K-1 for WS2 and (-0.82 +/- 0.15) mV K-1 for TiS3. Peltier elements were also constructed by connecting the P- and N-type films with graphite electrodes, achieving a thermopower value of up to 6.11 mV K-1 when the Peltier element had three junctions. This work demonstrates the potential application of semiconducting van der Waals materials in thermoelectric power generation and low-cost disposable electronic devices.
