AB  - Thermoelectric textiles that are able to generate electricity from heat gradients 
      may find use as power sources for a wide range of miniature wearable electronics. 
      To realize such thermoelectric textiles, both p- and n-type yarns are needed. The 
      realization of air-stable and flexible n-type yarns, i.e., conducting yarns where 
      electrons are the majority charge carriers, presents a considerable challenge due 
      to the scarcity of air-stable n-doped organic materials. Here, we realize such 
      n-type yarns by coating commercial sewing threads with a nanocomposite of 
      multiwalled carbon nanotubes (MWNTs) and poly(N-vinylpyrrolidone) (PVP). Our 
      n-type yarns have a bulk conductivity of 1 S cm(-1) and a Seebeck coefficient of 
      -14 muV K(-1), which is stable for several months at ambient conditions. We 
      combine our coated n-type yarns with 
      poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) dyed silk 
      yarns, constituting the p-type component, to realize a textile thermoelectric 
      module with 38 n/p elements, which are capable of producing an open-circuit 
      voltage of 143 mV when exposed to a temperature gradient of 116  degrees C and a maximum 
      power output of 7.1 nW at a temperature gradient of 80  degrees C.
