摘要：
A biological information detecting apparatus includes: an LC resonant pressure sensor including a resonant circuit including a capacitor and an inductor, and having a resonant frequency that changes depending on a change in external pressure applied to the capacitor； and an integrated circuit (IC) chip package including a coil type antenna radiating a radio frequency (RF) signal within a preset frequency band, wherein a change in the resonant frequency results in a change in a power transmission rate depending on a inductive coupling between the resonant frequency and a frequency of the RF signal. The IC chip package includes the coil type antenna disposed in a region overlapping the LC resonant pressure sensor in a plan view of the IC chip package.
