Abstract:
A interim power set implants arthritis piezoelectric ceramic vibrator, especially referring piezoelectric ceramic power supply circuit design and low-power consumption pressure adjust circuit design, belonging to medical implanted knuckle piezoelectric ceramic power set equipment technical area. This power set containing piezoelectric ceramic set, rectification circuit set, energy storage circuit set and voltage regulator, making use of the technology which conversing the energy produced by the piezoelectric ceramic in pressure condition to electrical energy, the electricity produced by the piezoelectric ceramic be pressed passing rectification circuit would store the energy in energy storage circuit, the energy storage capacitor providing pressure to voltage regulator circuit£¬the voltage regulator circuit exporting steady pressure for subsequent circuit work. Because the compressed time of piezoelectric ceramic implanted in articulation is discontinuous, so the electric supply manner of the equipment also is intermittent. It provides effective manner for implanting organism the knuckle bidirectional digital wireless pressure surveillance system.
