The invention discloses a charging system for implantable medical electronic equipment based on a multi-antenna array, comprising a multi-antenna array transmitting module and an implantable charging module. Radio platform, 8 power amplifiers and 8 radio frequency identification antennas, each general software radio platform is equipped with a radio frequency sub-board, and the transmission frequencies of the eight radio frequency sub-boards are set to different through the corresponding general software radio platform. In the same way, beamforming algorithms are installed in the UHD driver of each general software radio platform, and the clock distribution system provides 8 clock signals synchronously. 8 radio frequency identification antennas are connected one by one, and the implantable charging module is realized by micro RFID tags; the advantage is that there is no potential safety hazard, and the charging efficiency is high.
Description
technical field [0001] The invention relates to a charging system for implantable medical electronic equipment, in particular to a charging system for implantable medical electronic equipment based on a multi-antenna array. Background technique [0002] In recent years, implantable medical electronic devices have gradually replaced traditional portable medical electronic devices and become a global medical research and development hotspot. Compared with traditional portable medical electronic devices, implantable medical electronic devices are more dexterous and convenient in appearance or use, and can monitor health status in real time and even predict diseases. Such as an implantable cardiac pacemaker, an implantable cardiac pacemaker is an electronic therapeutic device implanted in the body, which emits electrical pulses powered by batteries through a pulse generator, and the electrical pulses are conducted to electrodes through wires. Stimulate the myocardium in contact...
