Carbon nanotubes based multi-directional strain sensor

• An investigation of the behavior an aligned CNT strain sensor, when strained at 45° regarding its alignment, is carried out. Two sensor configurations (D and Sq) are considered both sensors sensitive to strain. Relation between electrical anisotropy direction stablished. This small suitable as a quantifier indicator. In this work new carbon nanotubes (CNT) based multi-directional capable quantifying indicate foreseen. investigates electromechanical sensing patch in order validate capability. Vertically forests produced by chemical vapor deposition (CVD) then mechanically knocked down onto polyimide (PI) films. configurations, diamond sample) square (Sq sample), considered. The relative resistance ( ΔR/R 0 ) R B /R A upon increments analyzed compared previous results (0° 90° direction). Both samples, D Sq, correlation (0°, 90°) established. show that with only it possible quantify three directions.
