    • An embodiment of the device (1) has an external unit (2) that transmits a power signal to a wireless power receiver (7) in an implant (3). This received waveform provides the implant (3) with a sinusoidal input signal at a first frequency. This is fed to a rectifier (8) to provide a substantially direct current signal which is used as a power source for the implant (3). The sinusoidal input signal is also fed to a non-linear block (11), which modifies the input signal to provide a non- sinusoidal intermediate signal having a spectrum with at least one harmonic component at a second frequency different to the first frequency. The intermediate signal is fed to a filter (14) to provide an output signal substantially at the second frequency. The output signal may be used to transmit data to the external unit (2). In the event of a low quality communications link between the external unit (2) and the implant (3), the power signal may be modified so as to modify the output signal.
    • 设备(1)的实施例具有将功率信号发送到植入物(3)中的无线电力接收器(7)的外部单元(2)。 该接收的波形为植入物(3)提供具有第一频率的正弦输入信号。 这被馈送到整流器(8)以提供用作植入物(3)的电源的基本上直流的电流信号。 正弦输入信号也被馈送到非线性块(11),该非线性块(11)修改输入信号以提供具有至少一个与第一频率不同的第二频率的谐波分量的频谱的非正弦中间信号。 中间信号被馈送到滤波器(14)以提供基本上处于第二频率的输出信号。 输出信号可以用于向外部单元(2)发送数据。 在外部单元(2)和植入物(3)之间的低质量通信链路的情况下,可以修改功率信号以修改输出信号。
