Vibrational noise rejection in multilayer structured magnetoelectric sensor
Sensors and Actuators A: Physical(2014)
摘要
•We test the frequency dependence of the ME charge coefficients and the noise floor of the sensor.•We examine the ability to reject vibrational noises.•Giant ME effect has been found, the ME voltage coefficient reaches 890pC/Oe at low frequencies with a low noise floor of 32pT/Hz1/2 at 1Hz, which was very close to the estimated value (27pT/Hz1/2).•The results show an excellent ability to attenuate the vibrational noise by 91%.
