The embodiment of the invention relates to a temperature measurement patch, a temperature measurement system and a wearable article. The temperature measurement patch comprises a first information processing module, a temperature measurement module, a human body induction module, a first information transmission module, a power supply module and a protection module; the temperature measurement module, the human body induction module and the first information transmission module are connected with the first information processing module; the power supply module is separately connected with thefirst information processing module, the temperature measurement module, the human body induction module and the first information transmission module through a timing switch; and the first information processing module, the temperature measurement module, the human body induction module, the first information transmission module, the power supply module and the timing switch are in sealed arrangement in the protection module in a mutual spacing manner; therefore, a blank groove is formed mutually. The temperature measurement patch in the invention can complete body temperature measurement ofhuman bodies in a timed manner; abnormal reminding and alarm prompting are displayed and set through a user terminal; furthermore, the average power can be reduced; and the endurance can be increased.
