Abstract
A pressure sensor is for positioning within a structure. The pressure sensor may include a pressure sensor integrated circuit (IC) having a pressure sensor circuit responsive to bending, and a transceiver circuit coupled to the pressure sensor circuit. The pressure sensor may include a support body having a recess therein coupled to the pressure sensor IC so that the pressure sensor IC bends into the recess when the pressure sensor IC is subjected to external pressure.
