1. A passive temperature sensor patch, comprising: a sensor circuit, the sensor circuit including:
a radiofrequency identification (RFID) chip;
a dipole antenna, the dipole antenna including a first pole and a second pole, each of the first pole and the second pole having a width of approximately 33 mm and a height of approximately 34 mm; and
a plurality of inductors extending between the first pole and the second pole, each of the plurality of inductors having a length of approximately 10.2 mm, wherein the width and the height of the first pole and the second pole and the length of each of the plurality of inductors providing optimization of a gain of the dipole antenna when the passive temperature sensor patch is affixed to a biological material; and
a layer of base material, the sensor circuit being in the layer of base material and the layer of base material being configured to permit a signal transfer between the sensor circuit and a surrounding environment.
