Outline of Final Research Achievements

In order to realize a battery-less implant platform, we have developed a resonance and rectifier circuit (Cockcroft-Walton circuit) for receiving and boosting weak electromagnetic waves. In the radio frequency band, we succeeded in reducing the influence of the parasitic elements of the rectifier circuit that follows by increasing the output voltage amplitude. We have succeeded in realizing a basic circuit for medical applications.
