Acoustically Mediated Piezoelectric Antenna for Ultracompact Biomedical Electronics
Designing ultracompact antennas for implantable bioelectronics is challenging because antennas typically require a size comparable to the electromagnetic (EM) wavelength for high performance. This study presents an acoustically mediated piezoelectric (AMP) antenna that leverages the direct coupling of the mechanical resonance with the quasi-static electric field component for the first time. Our experiments demonstrate a 12 dB enhancement in antenna reception near the mechanical anti-resonance frequency, with the antenna size reduced to 1/300th of the EM wavelength. The power transfer efficiency (PTE) of the AMP antenna shows a strong correlation with the quality factor and impedance value at the anti-resonance frequency, which can further be effectively enhanced through antenna arraying. In a 25-element array, we achieve a PTE of 0.0539% at 50 mm, with a figure of merit (FoM) for wireless power transfer surpassing existing technologies around 400 MHz. This work underscores the potential of the AMP antenna for applications in implanted bioelectronics.
期刊介绍：
IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
