Abstract

The highly miniaturized and integrated electronic devices have demanded contactless current sensors with scale miniaturization, structure flexibility, self-powering and heat resistance. Herein, a novel magnetoelectric current sensor (MCS) based on polylactide/VB2 composites and FeCoV is prepared using in-situ coating and poling-free methods. The use of polylactide/VB2 composite makes the MCS self-powered and heat resistant, and the use of FeCoV makes the MCS highly flexible. The in-situ coating and poling-free methods endow the polylactide/VB2 composite and FeCoV good interfacial coupling. As a result, the MCS possesses good linearity over 0.999 and high sensitivity of 0.64 mV/A to the external current, even at a high temperature of 120 °C. Besides, the MCS presents high durability after 200 000 cycles. The MCS with mini size, self-powering, heat resistance, high flexibility and durability has great potential in safety monitoring of electronic devices fields.
