COMMUNICATION DEVICE

WIPO Patent Application WO/2007/066447

A1

In a sheet-like communication device (100) which can easily charge a power supply source to communication elements, a second conductive layer (102) is disposed substantially in parallel with a first conductive layer (101), an electrode (201) of a communication element (105) is capacitively coupled with the first conductive layer (101), an electrode (202) is capacitively coupled with the second conductive layer (102), the communication device (105) rectifies voltage changes between the electrode (201) and the electrode (202) in response to those between the first conductive layer (101) and the second conductive layer (102) and charge such rectified voltage changes as a power supply source, the communication element (105) communicate the other communication devices by the voltage changes between the first conductive layer (101) and the second conductive layer (102) or electro-magnetic waves propagated between them.
