PROBLEM TO BE SOLVED: To allow transmitting data of health conditions and the like without any operation. SOLUTION: In a signal transmission system, a wearable appliance 30 is contacted to a user 10 via an electrode 31. When the user uses a toilet, a transmission path 13 of liquid is formed between a human body and a toilet bowl 60. A main transmission path of signals is formed in such a route from the appliance 30, the electrode 31, the user (human body) 10 to an electrode 43 of the bowl 60, so that a return transmission path 12 is formed by a neighboring electromagnetic field. Thus, information is transferred between the appliance 30 and a personal computer 50. More specifically, the data of health conditions from a heartbeat sensor 39 and the like is transmitted to the computer 50. |
