         4 . The heater ( 10 ) as defined in any one of the preceding claims, wherein a number of elongated heating elements ( 12 ) is smaller or equal to a number of grooves ( 22 ). 
     
     
         5 . The heater ( 10 ) as defined any one of the preceding claims, wherein at least one of the elongated heating elements ( 12 ) comprises a heating material ( 13 ), the heating material ( 13 ) comprising a first zone at a first extremity ( 14 ) of the at least one of the elongated heating elements ( 12 ) and a second zone at a second extremity ( 15 ) of the at least one of the elongated heating elements ( 12 ), the first and second zone enabling to reach respectively a first temperature (T 1 ) and a second temperature (T 2 ) different from each other. 
     
     
         6 . The heater ( 10 ) as defined in any one of the preceding claims, wherein at least one of the elongated heating elements ( 12 ) comprises a heating part comprising the heating material and a diffusing part comprising a diffusing material configured to transfer the heat produced by the heating material and diffuse the heat by conduction hence generating a heat gradient. 
     
     
         7 . The heater ( 10 ) as defined in any one of the preceding claims, wherein the at least one of the elongated heating elements ( 12 ) comprises at least one patterned zone configured to have a higher electrical current density. 
     
     
         8 . The heater ( 10 ) as defined in the preceding claim, wherein the patterned zone comprises at least one serpentine and/or at least one pattern of holes and/or at least one pattern of slots. 
     
     
         9 . The heater ( 10 ) as defined in  claim 6 , wherein the frame ( 11 ) comprises the heating material and at least one of the elongated heating elements ( 12 ) comprises the diffusing material configured to transfer the heat produced by the heating material. 
     
     
         10 . The heater ( 10 ) as defined in any one of the preceding  claims 5  to  9 , wherein the heater is configured to generate at least one heating site located on the at least one of the elongated heating elements ( 12 ) to heat a specific location in the consumable article ( 20 ). 
     
     
         11 . The heater ( 10 ) as defined in the preceding claim, wherein the at least one heating site is further configured to heat a wicking element arranged in the consumable article ( 20 ). 
     
     
         12 . A consumable article ( 20 ) for an aerosol generation device, which is intended to connect with a heater ( 10 ) according to  claims 1  to  11 , the consumable article ( 20 ) being configured to contain an e-liquid and having a shell ( 21 ) comprising grooves ( 22 ) arranged on the surface of the shell ( 21 );
 wherein the grooves ( 22 ) are configured to engage with corresponding elongated heating elements ( 12 ) arranged on the heater ( 10 ), at a time of connecting. 
 
     
     
         13 . The consumable article ( 20 ) according to  claim 12 , wherein the grooves ( 22 ) are configured to receive elongated heating elements ( 12 ) from the heater ( 10 ). 
     
     
         14 . The consumable article ( 20 ) according to any one of  claims 12  and  13 , further comprising at least a wicking element configured to be in contact with the elongated heating elements when these are engaged and thereby present e-liquid to be heated and transformed into aerosol.
