Magnetic based multiferroic antennas are superior to electrical antennas in dielectric-cluttered environments like the human body due to the electric signal from conventional antennas shorting in lossy environments while magnetic signals are free to propagate. In this work, we investigate a magnetic-based multiferroic embeddable antenna consisting of piezoelectric and magnetoelastic materials for inductively coupled communications within the human heart at 125 kHz. This presentation describes the analysis, fabrication, and testing of an axial extension mode multiferroic antenna. Dynamic mechanical, electrical, and magnet field strength testing data shows a promising new approach for communicating in dielectric-cluttered environments like the human anatomy.
