An intestinal peristalsis detecting device comprises a radio frequency (RF) signal generator, an antenna, and a mixer. After the RF signal generator sends a pulse signal, the antenna receives the pulse signal and emits a pulse electromagnetic wave to an organism. Thereafter, the antenna receives a response pulse electromagnetic wave reflected from the organism to generate a response pulse signal. The mixer couples with the RF signal generator and the antenna to mix the pulse signal and the response pulse signal. |
