Korea Advanced Institute of Science and Technology (KAIST) researchers have developed a sensor that can measure goosebumps on the human body in real time.
The device uses a stick-on transparent conductive polymer to measure how big the bumps are, and how long they last.
The system works by recording a drop in the sensor's ability to store an electrical charge, known as capacitance, caused by it being deformed by the buckling of the skin's surface.
Previous research has shown that goosebumps can be used to deduce changes in a subject's emotional state brought on by music, moves, and other causes. "In the future, human emotions will be regarded like any typical biometric information, including body temperature or blood pressure," says KAIST professor Young Ho-cho.
It is suggested the technology could eventually be used to create a kit to personalize advertisements, music, and other services based on the user's reactions.
