Researchers from KAIST, South Korea have developed a thin, wearable device that measures goosebumps.
Technically known as piloerection, goosebumps are tiny skin elevations that occur in response to emotion or changes in temperature.
Their formation deforms the device’s polymer sensor, decreasing its capacitance (its ability to store an electrical charge). This decrease is then used to estimate the goosebumps’ height and duration.
With future research such a device could be used to gauge the emotional state of its wearer.Read more at KAIST
