We present a method to fabricate handcrafted thermoelectric devices on standard office paper substrates.The devices are based on thin films of WS2,Te,and BP(P-type semiconductors)and TiS3 and TiS2(N-type semiconductors),deposited by simply rubbing powder of these materials against paper.The thermoelectric properties of these semiconducting films revealed maximum Seebeck coefficients of(+1.32±0.27)mV K-1 and(-0.82±0.15)mV K-1 for WS2 and TiS3,respectively.Additionally,Peltier elements were fabricated by interconnecting the P-and N-type films with graphite electrodes.A thermopower value up to 6.11 mV K-1 was obtained when the Peltier element were constructed with three junctions.The findings of this work show proof-of-concept devices to illustrate the potential application of semiconducting van der Waals materials in future thermoelectric power generation as well as temperature sensing for low-cost disposable electronic devices.
