Abstract

This paper reports a parylene film antenna integrating a CMOS rectifier chip for wireless neural recording devices. An implanted antenna requires the flexibility to fit the shape of brain surface. In addition, an integrating technology with solid-state and flexible substrate is needed because a silicon chip can provide high-performance and multi-functionality. The fabricated device that packages antenna, transformer, and rectifier generates more than 1.5V and achieves a power transmission efficiency of 0.086 %.
