| Abstract | |
Non-contact electrostatic measurements were used to the characterization of flexoelectric potentials in dielectrics under tensile, compressive, and flexural loads. Kelvin probes are capable to detect localized potential gradients on stretched natural latex that would hardly be detected at the macroscopic scale using standard methods for flexoelectric characterization. The high deformability of rubbers under tensile (or compressive) loads or dielectrics in fully folded states during flexural tests is a really challenging task for measurements using attached or compliant electrodes to detect flexoelectricity but is easily assessed with Kelvin probes. Moreover, non-contact electrostatic measurements are effective to avoid triboelectric effects, which are important sources of electricity on contacting surfaces. (AU) | |
