Embodiment
[0027] like figure 1 As shown, this embodiment includes: an external wireless device located outside the body, an internal wireless device located inside the body, and a data reverse transmission module, wherein: the external wireless device receives the encoded image signal and transmits it to the internal wireless device through wireless after modulation. The wireless device in the body rectifies and demodulates and receives the driving power and the received signal respectively. The data reverse transmission module monitors the impedance and temperature information in the body and sends them to the wireless device outside the body through a wireless connection in turn. The reverse demodulation circuit in the body is based on Impedance and temperature information is recovered from signals received by the external wireless device and input power is adjusted by the external device.
[0028] like figure 2 As shown, the external wireless device includes: an encoding circuit, a...
