Wireless power and data transmission systems are important components in bioelectronics. Achieving resonance at the data transmission frequency without negatively impacting the efficiency at the power transmission frequency may enhance data transmission capability. In this letter, a new system referred to as tuned inductor four capacitor is proposed to achieve resonance at the data transmission frequency of a wireless telemetry system without significantly affecting the efficiency at the power transmit frequency; as a result, this leads to increased voltage and current gains and reduced reflections at the data transmit frequency when compared to an equivalent, traditional, two-coil system. The performance of the proposed design is demonstrated through a system implementation characterized by a transmit coil of 40 mm diameter and receive coil of 15 mm diameter, with a distance between them varied from 17 to 40 mm. This system is experimentally compared with the equivalent two-coil system that has the same transmit and receive coil footprint and layout but conventional transmitter matching circuitry. Results show that, at the data telemetry frequency, there is no reflection, the voltage gain is 60% higher than that of the traditional two-coil system, whereas the current gain is 250% higher.

具有独立电源和数据频率谐振的无线遥测系统

无线电能和数据传输系统是生物电子学的重要组成部分。在数据传输频率实现谐振而不负面影响电力传输频率的效率可以增强数据传输能力。在这封信中，提出了一种称为调谐电感四电容器的新系统，以在无线遥测系统的数据传输频率下实现谐振，而不会显着影响功率传输频率下的效率；因此，与等效的传统双线圈系统相比，这会增加电压和电流增益并减少数据传输频率处的反射。所提议设计的性能通过一个系统实现来证明，该系统实现的特点是直径为 40 毫米的发射线圈和直径为 15 毫米的接收线圈，它们之间的距离从 17 到 40 毫米不等。该系统与等效的双线圈系统进行了实验比较，该系统具有相同的发射和接收线圈占用空间和布局，但传统的发射器匹配电路。结果表明，在数据遥测频率下，没有反射，电压增益比传统双线圈系统高60%，而电流增益高250%。该系统与等效的双线圈系统进行了实验比较，该系统具有相同的发射和接收线圈占用空间和布局，但传统的发射器匹配电路。结果表明，在数据遥测频率下，没有反射，电压增益比传统双线圈系统高60%，而电流增益高250%。该系统与等效的双线圈系统进行了实验比较，该系统具有相同的发射和接收线圈占用空间和布局，但传统的发射器匹配电路。结果表明，在数据遥测频率下，没有反射，电压增益比传统双线圈系统高60%，而电流增益高250%。
