Abstract

The invention discloses a two-degree-of-freedom wireless energy transmission device and belongs to the technical field of energy supply of human body implantation equipment. The problems that a coupling coefficient between coils is reduced so as to reduce the energy transmission when a load position is changed in the conventional wireless energy transmission device are solved. The device comprises an external energy transmitting part and an internal energy receiving part, wherein the energy transmitting part comprises a double-resonance coil; the energy receiving part is mainly a coil which is distributed and wound on a cylindrical supporting piece; the coil is uniformly distributed on the outer surface of the cylindrical supporting piece, is arranged according to the circumference in a dispersing mode and is divided into two parts; each part accounts for 1 / 2 of the circumferential direction; and a first receiving coil and a second receiving coil have two-degree-of-freedom omnidirectional properties. The two-degree-of-freedom wireless energy transmission device is applicable to the energy supply of the human body implantation equipment.

Description

technical field [0001] The invention relates to a two-degree-of-freedom wireless energy transmission device, which belongs to the technical field of energy supply for human implantation equipment. Background technique [0002] In recent years, human implanted devices have become a new research direction. Some biological signals and images can be directly detected by placing the sensor inside the human body. Facilitate rapid diagnosis and reduce patient suffering. However, due to the particularity of the human body, the miniaturization and high-performance requirements of internal devices, the usual way of carrying batteries is difficult to meet the requirements in terms of safety, energy size, and volume weight. Therefore, using wireless energy transmission to supply sensor energy in real time has become an effective solution. [0003] The wireless energy transmission method transmits the energy wirelessly to the electrical device inside the human body through the couplin...
