Smart underwear is equipped with sensors that can measure human physiological indicators and can monitor human condition at any time. Through direct contact with human skin, the sensor can measure whether human blood pressure, heart rate and blood alcohol content are in normal state.

This smart bra was designed by a professor at Southampton University in England. This bra is equipped with sensors, which can monitor the condition of the heart and skin. The data collected by the bra will be transmitted to the smartphone application for analysis, reminding the wearer when he may have the impulse to "eat emotionally" and making suggestions.
