Abstract
In this paper, we present a new and high efficient wireless power transfer system for biomedical implants. The system composes of a dual-band implantable antenna, a wearable patch antenna, and a voltage doubler rectifier. The transmitter has an impedance bandwidth below -10 dB from 1.461 up to 1.48 GHz. On the other hand, the dual-band receiver has a 23.4% and 16.5% impedance bandwidths at 915 MHz (the industrial, scientific and medical ISM) and 1.47 GHz, respectively. Good agreement has been observed between the measured results inside minced pork and salmon fish. Finally, a 8.7 x 3.15 mm2 ultra-small rectifier has been developed to be integrated with the implantable device for wireless power transfer purposes.
