It is a big challenge to in situ monitor the health status of high-temperature magnetic equipment such as electric motors and generators since it is difficult to achieve a high-temperature magnetoelectric sensor. Here, the Pb(Zr0.52Ti0.48)O3 film with a ferroelectric Curie temperature of 400 °C and the Metglas alloy slice with a magnetic Curie temperature of 430 °C were combined by using a high-temperature inorganic glue to achieve a high-temperature magnetoelectric sensor. The magnetoelectric coefficient αE of the flexible sensor is as high as 104 V/(cm Oe) at 25 °C, 63.6 V/(cm Oe) at 200 °C, and 39.7 V/(cm Oe) at 330 °C. Besides, the magnetic sensor has a detection accuracy of ∼0.3 nT at 25–330 °C. Most importantly, the high-temperature sensor is flexible, high precision, low cost, light weight, and low power consumption simultaneously. |
