A smart bra with physiological sensors was presented in [120]. The goal is to perform emotion prediction on the basis of
the output of a set of physiological sensors. The device is designed to track heart rate and respiration with an electrocardiogram
(EKG) sensor, skin conductance with an electrodermal activity (EDA) sensor, and movement with a 3-axis accelerometer
and a 2-axis gyroscope. Recently, the company First Warning Systems [121] has taken this idea farther by designing a
smart bra with temperature sensors that track the circadian rhythm-based temperature variances of cell cycles to identify
abnormalities at the earliest stages of cell augmentation [122].
