摘要	A low-power, short-range communications system (Figure 1) is disclosed. The communications system comprises a transmitter that is operative to generate a high impedance signal and a receiver that is operative to detect the high impedance signal. In this respect, the transmitter and the receiver (Figure 1, elements 12 and 14) are capacitively coupled by the high impedance electric field generated in response to the high impedance signal. Accordingly, information from the transmitter to the receiver is sent via the high impedance electric field. In accordance with the present invention, the transmitter is configured to generate the high impedance signal with a frequency in the range from about 20 KHz to 10 MHz. Similarly, the voltage of the high impedance signal is from about 1 Vrms to 300 Vrms.
