発明の名称 (英語) RADIO DEVICE, DETECTING DEVICE, DETECTING SYSTEM, AND RADIO COMMUNICATION METHOD UPDATE
発明の概要(英語) A radio device (10) is a device introduced into a living body (LB). The radio device (10) transmits a radio signal to the outside of the living body (LB) at a frequency that is higher than a maximum value frequency at which a loss coefficient, which is a ratio between an imaginary part of a dielectric constant of water and a real part of said dielectric constant, has a maximum value due to dipole polarization, said frequency being a frequency from among frequencies included in a frequency band comprising Ultra High Frequency (UHF), Super High Frequency (SHF), Extremely High Frequency (EHF) and Tremendously High Frequency (THF).
従来技術、競合技術の概要(英語) BACKGROUND ART
Is introduced into the inside of a living organism is transmitted wirelessly by the wireless device signal, received by an external device located outside the living body to a wireless communication system has been known (for example, Non-Patent Document 1 and non-patent reference 2).
However, the living body includes, contains a number equivalent to the water. Therefore, from the inside of a living organism is the propagation of the signal to the outside of a living body, water by the propagation of the signal represented by the sufficiently high accuracy. In addition, the signal transmitted by the wireless device power, the loss caused by the propagation of water, the higher the frequency of signal increases, is considered to be.
Therefore, the wireless communication system, the transmission of signals by the wireless device as a frequency that is used, from 1MHz to 400MHz using a frequency.
