TL;DR: In this article, a power transfer system with adaptive control technique to eliminate the power variations due to the loading or coupling coefficient changes is proposed, where a maximum of 250mW power is transmitted through an optimized coil pair driven by a Class-E power amplifier.

TL;DR: The design procedure starts with the formation of equivalent circuits, followed by the analysis of the loss of the rectifier and coils and the H-field for induced voltage and current and an experimental power link is implemented with an overall efficiency of 67% at the optimal distance of 7 mm between the coils.

TL;DR: To achieve high performance data transmission, the cross-coupling between the power coils and data coils have to be taken into consideration, and design equations have been derived and shown that the signal to noise (interference) ratio could be significantly reduced and the resulting data transmission could fail if only the data link coupling is optimized.

TL;DR: A prototype of dual band telemetry for a retinal prosthetic device has been built and experimental results show that both power and data can be transmitted and high data rate can be achieved without compromising the power transmission efficiency.

TL;DR: To enhance the BP system performance, both the optimization of the integrated PPG receiver design and the reduction of the LED driver power consumption are introduced and useful design considerations are proposed to improve the PPG-based BP system accuracy.
