Device for contactless power transfer to human implanted devices

Abstract

The embodiment of the invention provides an apparatus of performing contactless electric energy transmission on a human implantable device, comprising a human implantable device and an internal coil arranged in a human body, and an external coil and an external control device arranged outside the human body. The external control device converts electric energy into high frequency electromagnetic waves, the external coil transmits the high frequency electromagnetic waves loaded with control information to the internal coil through electromagnetic coupling, the internal coil transmits the high frequency electromagnetic waves loaded with control information to the human implantable device, and the human implantable device converts the high frequency electromagnetic waves into electric energy, and utilizes the electric energy to charge the battery of the human implantable device. The apparatus of the embodiment can effectively perform contactless electric energy transmission on the human implantable device outside a human body, break the limits of battery power on the service life of human implantable devices such as a cardiac pacemaker, meet the requirement of special functions, and effectively prolong the service life of the human implantable device.

Description

technical field [0001] The invention relates to the technical field of non-contact power transmission, in particular to a device for non-contact power transmission to human implanted equipment. Background technique [0002] In the past ten years, wireless charging technology has become one of the most popular research and development directions. At present, there are three main ways to realize wireless charging, namely electromagnetic induction, radio waves and resonance. The most common charging pad solution uses electromagnetic induction, which induces current through primary and secondary coils to transfer energy from the transmitter to the receiver. The radio wave is another relatively mature technology. The miniature high-efficiency receiving circuit of the radio wave can capture the radio wave energy bouncing off the wall, and maintain a stable DC voltage while adjusting with the load. A third technology under investigation is electromagnetic resonance. The wireless ...

Problems solved by technology

[0005] At the same time, most of the immature human implantable wireless charging devices currently on the market do not have an intelligent internal charging management system, poor charging protection performance, and do not have device identification capabilities, and cannot judge the current power status of the charging device. Then it will cause the blindness of charging at the sending end and the waste of electric energy. The internal equipment of the human body is easily disturbed by the outside world, which poses a threat to human safety.
