         3 . The yarn according to  claim 1 , wherein a number of the at least one potential-generating filament is 20 or more. 
     
     
         4 . The yarn according to  claim 1 , wherein a number of the at least one potential-generating filament is 20 to 600. 
     
     
         5 . The yarn according to  claim 1 , wherein the at least one potential-generating filament contains at least one piezoelectric material. 
     
     
         6 . The yarn according to  claim 5 , wherein the at least one piezoelectric material includes polylactic acid. 
     
     
         7 . The yarn according to  claim 5 , wherein the at least one piezoelectric material contains no additives. 
     
     
         8 . The yarn according to  claim 5 , wherein the at least one piezoelectric material contains a hydrolysis inhibitor. 
     
     
         9 . The yarn according to  claim 1 , further comprising a dielectric material around the at least one potential-generating filament. 
     
     
         10 . The yarn according to  claim 9 , wherein the dielectric material completely covers the at least one potential-generating filament. 
     
     
         11 . The yarn according to  claim 1 , wherein the yarn is a combined yarn including:
 a first false-twisted yarn in which a first plurality of the at least one potential-generating filament are twisted in a first direction; and   a second false-twisted yarn in which a second plurality of the at least one potential-generating filament are twisted in a second direction opposite the first direction.   
     
     
         12 . The yarn according to  claim 1 , wherein the electric potential is a surface potential greater than 0.1 V. 
     
     
         13 . A fabric comprising the yarn according to  claim 1 .
