这项工作描述了遥测系统的外部便携式部分的功能,用于为骨科植入物内内置的植入式电气设备供电和询问,以实时采集应变、载荷、温度、湿度和其他相关数据(例如来自惯性传感器)。该系统包含电池供电的感应激励器和解调器,用于远程为植入电子设备供电并解调从植入器械传输的信号。由于内部线圈的外壳,在外部和内部调谐电路之间获得了足够的电感耦合,从而能够在同一电感链路上同时传输电力和数据。研究了该系统与一种特定植入物一起使用时的实际性能,并与相关理论进行了一些对应。确定了与功率效率和数据重建相关的性能因素。
This work describes the functions of the external, portable part of a telemetry system for powering and interrogating implantable electrical devices built within orthopaedic implants for real-time data acquisition of strain, load, temperature, humidity and other relevant data (eg from inertial sensors). The system contains a battery powered inductive energiser and demodulator to remotely power the implant electronics and demodulate the signals transmitted from the implanted device. Due to the housing of the internal coil, sufficient inductive coupling is obtained between the external and internal tuned circuits to enable simultaneous power and data transmission over the same inductive link. The actual performance of this system when used with one specific implant was studied, and some correspondence made to the relevant theory. Performance factors relating to both power efficiency and data reconstruction were identified.
