<p>A signal transmission device capable of transferring information when a liquid is poured. The container body (201) of a transmitter container (20) holds a conductive liquid (402). The container body (211) of a receiver container (21) has a data-reception-confirming display (306) attached thereto. The container body (201) and the container body (211) are electrically connected together at a specified impedance by means of the liquid (402). Since digital data is modulated by a carrier as much as 10 MHz, an electromagnetic field is generated, especially a fly-back line (404) by a near electromagnetic field component is generated to enable communication from the transmitter container (20) to the receiver container (21).</p> |
