Abstract
Due to size limitations and limited battery life, many implant biomedical devices need to be powered inductively. This paper introduces a small size and efficient spiral square coils at 13.56 MHz to be used for bio-implantable devices. We applied our design methodology with theoretical closed-form equations using MATLAB to optimize the wireless link of a 10 mm2 implantable device example with 10 mm relative distance. The results showed that optimized coil pairs achieved 73.46% efficiency at face to face relative distance of 10 mm in the air. All results are validated with the simulation using an electromagnetic field solver HFSS 14.1.
