                         (VACNT/PDMS) stretchable sensor for aircraft structures and 
                         polymer composites. The VACNT growth method from thermal CVD with 
                         camphor and ferrocene precursors create a dense and homogeneous 
                         CNT structure with many ohmic conducting paths that surpass any 
                         more resistive tunneling phenomena. The extensive AC/DC 
                         piezoresistive performance investigation shows ohmic conduction. 
                         The VACNTs/PDMS sensor presented high linearity (r2 = 0.99) under 
                         \∼20 % strain with an average gauge factor of 3.28 at DC 
                         measurements and minor resistance variations (0.052 %) attributed 
                         to the copper terminals electrodeposition. An important feature is 
                         the resistance value compatible with conventional extensometry 
                         equipment. The DC gauge factor was \∼60 % higher than the 
                         conventional metallic strain gauge allowing measurements within a 
                         wider strain range.",
