This paper investigates the transient magnetoelectric (ME) response of the symmetric Terfenol-D/PZT/Terfenol-D laminate structure driven by transient current. The time-domain output voltages are investigated in detail under the currents generated by the square, sine, and triangle transient voltages. The damping oscillation phenomenons at natural frequency are observed with the fast-changing current and weaken when the width of the transient currents are equal to the times of the natural period of laminate. Furthermore, the transient ME responses driven by the 8/20μs lightning current are also investigated. For detecting the amplitude of the 8/20μs lightning current, the detection sensitivity reaches 6.8 mV/A in the range of 90–2742 A. These results show that the ME composite is an ideally sensing device for the lightning current sensing.
