The coexistence of electric polarization and magnetization in multiferroic materials provides great opportunities for realizing magnetoelectric coupling, including electric field control of magnetism, or vice versa, through a strain mediated magnetoelectric coupling in layered magnetic/ferroelectric multiferroic heterostructures. The strong magnetoelectric coupling has been the enabling factor for different multiferroic devices, which, however, has been elusive, particularly at RF/microwave frequencies. In this presentation, I will cover the most recent progress on new integrated RF magnetoelectric NEMS (nanoelectromechanical system) based sensors and antennas [1-9]. Specifically, we will introduce magnetoelectric multiferroic materials and their applications in different devices, including novel ultra-compact RF NEMS acoustic magnetoelectric antennas immune from ground plane effect with < l0/100 in size, self-biased operation, and ground plane immunity. These magnetoelectric antennas are smart antennas with picoTesla magnetic field sensitivity, and with orders of magnitude improved figure of merit for wireless power, transfer compared to state-of-the-art technologies. We will also cover ultra-sensitive RF NEMS magnetoelectric magnetometers with ultra-low noise for DC and AC magnetic fields sensing and magnetoelectric signal processing devices. These novel ferroic materials and devices show great promise for applications in compact, lightweight and power-efficient sensors, antennas, and tunable components for radars, communication systems, biomedical devices, IoT, etc.
