Abstract
An apparatus includes first and second chips. The first chip includes a first transmission control portion to generate a transmission signal, and a first transmitting coil connected to the first transmission control portion to transmit the transmission signal. The second chip includes a second receiving coil capable of receiving the transmission signal by being inductively coupled with the first transmitting coil, and a second detection portion to detect a voltage or current applied to the second receiving coil. The first and second chips are in close proximity to enable wireless communication through inductive coupling. The second detection portion is configured to detect, when a change in voltage or current occurring in the second receiving coil satisfies a predetermined condition, a change in relative position between the first chip and the second chip, or vibration applied to the first and second chips, pressure change, temperature change, or electromagnetic wave.
