Considering the significant safety incidents arising from the fatigue-induced operations of tower crane drivers in prefabricated building construction, this study proposed the utilization of a new portable semi-dry electrode for real-time monitoring of the cognitive fatigue levels in tower crane drivers, aiming to mitigate instances of unsafe operational conduct. This type of semi-dry electrode possesses the merits of facile placement and low impedance, rendering it conducive for application in construction settings. Furthermore, the study applied Multifractal Detrended Fluctuation Analysis (MF-DFA) to analyze the electroencephalogram (EEG) features of tower crane operators. Evaluation and comparison using the traditional wet electrode and the new semi-dry electrode to extract the EEG features show that the performance of the novel semi-dry electrode closely approximates that of the traditional wet electrode, effectively tracking alterations in the cognitive fatigue indicators among tower crane drivers during prefabricated building construction. These findings contribute to the detection of the mental state of tower crane drivers and the identification of physiological characteristics associated with unsafe conduct in the actual process of prefabricated construction, thereby enhancing construction safety.
