| 摘 要： | Current-voltage measurements obtained from lead zirconate titanate/nickel bilayered hollow cylindrical magne-toelectric composite showed that a sinusoidal current applied to the copper coil wrapped around the hollow cylinder circumference induces voltage across the lead zirconate titanate layer thickness. The current-voltage coefficient and the maximum induced voltage in lead zirconate titanate at 1 kHz and resonance (60.1 kHz) frequencies increased linearly with the number of the coil turns and the applied current. The resonance frequency corresponds to the electromechanical resonance frequency. The current-voltage coefficient can be significantly improved by optimizing the magnetoelectric structure geometry and/or increasing the number of coil turns. Hollow cylindrical lead zirconate titanate/nickel struc-tures can be potentially used as current sensors.

| Abstract: | Current--voltage measurements obtained from lead zirconate
titanate/nickel bilayered hollow cylindrical magnetoelectric
composite showed that a sinusoidal current applied to the copper
coil wrapped around the hollow cylinder circumference induces
voltage across the lead zirconate titanate layer thickness. The
current--voltage coefficient and the maximum induced voltage in lead
zirconate titanate at 1~kHz and resonance (60.1~kHz) frequencies
increased linearly with the number of the coil turns and the applied
current. The resonance frequency corresponds to the
electromechanical resonance frequency. The current--voltage
coefficient can be significantly improved by optimizing the
magnetoelectric structure geometry and/or increasing the number of
coil turns. Hollow cylindrical lead zirconate titanate/nickel
structures can be potentially used as current sensors. |
