美国Ames研究中心的Fryer研制成一种遥控颅内压监测装置。它是由刚性金属膜片电容换能器组成的新型埋植式压力监测器,其稳定性好,能长期使用。监测器中的整流器将射频能转换成直流电以驱动电子装置。由于不带电源,也就没有导线穿过头皮,所以能长期植于体内。这种柱形监测器的直径和长度均为1厘米,由能量接受线圈、整流器/调节器、振荡器、输出阻尼器和发射线圈等组成。振荡器的频
Fryer developed by the Ames Research Center in the United States has developed a remote-controlled intracranial pressure monitoring device. It is a new type of implanted pressure monitor composed of rigid metal diaphragm capacitive transducers with good stability and long-term use. The rectifier in the monitor converts the RF energy into DC to drive the electronics. Because there is no power, there is no wire through the scalp, so long-term implantation in the body. This cylindrical monitor is 1 cm in diameter and length and consists of an energy-receiving coil, rectifier / regulator, oscillator, output damper and transmitter coil. Oscillator frequency
