八、采用“射频功率传送笼”来供能的植入式遥测系统采用“射频功率传送笼”来供能的植入式遥测系统主要用来研究在笼中自由活动的动物生理。一个典型的系统如图13(a)所示。它包括射频功率驱动单元、金属笼子、植入单元和接收单元四大部分。射频功率驱动单元通过金属笼子向受检者(动物)内的植入单元射送射频能量。体内生理信息在植入单元中经调制后向体外发送,由体外的接收单元接收解调,接收单元还同时提供系统控制脉
Implantable telemetry system powered by “RF power transfer cage” An implanted telemetry system powered by “RF power transfer cage” is mainly used to study animal physiology that is freely moving in a cage. A typical system is shown in Figure 13 (a). It includes four parts of RF power driver unit, metal cage, implant unit and receiver unit. The RF power drive unit emits radio frequency energy through the metal cage to the implanted unit in the subject (animal). In vivo physiological information in the implant unit after modulation sent to the body by the external receiving unit to receive demodulation, the receiving unit also provides system control pulse
