Abstract

The subject of the invention is a spring sensor element 1, comprising carbon nanotubes 6 on a carrier 2, wherein the carbon nanotubes 6 are arranged in CNT blocks 10, 20, 30, 40, wherein the carbon nanotubes 6 of each CNT block 10, 20, 30, 40 preferably have the same length and the same alignment with respect to the carrier 2, wherein at least the highest one of the CNT blocks 10, 20, 30, 40 is arranged nearby at least two electric contacts 60, 61, 62. The spring sensor element 1 has at least one additional neighboring CNT block 20, 30, 40 of the height H2 in addition to the first CNT block 10 of the height H1, wherein the heights H1 and H2 differ by a factor of at least 2.
