Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of wireless power supply, in particular to an intelligent implantable wireless power supply kit. BACKGROUND

[0002] In order to facilitate real-time or timing monitoring of data in the patient's body, implantable monitoring sensors have been widely used in clinical practice, and doctors are more familiar with their operation and interpretation. There are significant deficiencies in the traditional implantable monitoring sensor technology field. Specifically, the traditional implantable monitoring sensor mostly uses active wired or battery-powered mode, which has exposed a series of problems in actual application. In terms of volume, active wired sensors need wires for power supply and data transmission, resulting in a larger overall volume, which not only increases the difficulty and risk of implantation surgery, but also limits the application of the sensor in a small space. On the other hand, due to the size limitation of the sensor, the internal temperature measuring element and temperature sensing element are often difficult to achieve the ideal size and layout, thereby affecting the thermal response time and temperature measurement accuracy of the sensor. Especially when measuring high-temperature environment or rapidly changing temperature field, the hysteresis and error of the sensor are particularly prominent. In addition, temperature drift is also an important factor affecting detection accuracy. Due to the combined effects of sensor materials, circuit design, and changes in working environment temperature, the output signal of the sensor will shift over time, i.e. temperature drift. This drift will directly cause the deviation of the measurement result, reducing the reliability and accuracy of the sensor. Therefore, the present disclosure provides an intelligent implantable wireless power supply system that can be wirelessly powered and data transmitted while ensuring that the volume meets the use needs.
