Sensors are used to measure a range of biological activity of an individual who is being monitored. The biological activity can, in turn, be used to determine health status, mental states such as emotional and cognitive states, and so on. One leading biological activity is electrodermal activity, or electrical characteristics of skin. Electrodermal activity is a property of a body and varies depending on skin temperature, humidity, pressure, etc. Electrodermal activity has been used to measure heart rate, heart rate variability, breathing, and other unconscious activities. Electrodermal activity is used for various applications including stress control. Electrodermal activity has been used in psychological research into emotional and cognitive states of monitored individuals. A leadless, wearable sensor that is built into a glove, a wristband, or other garment is worn by an individual. Electrodermal activity, skin temperature, heart rate, or heart rate variability data are captured by the wearable sensor. In addition, a pressure sensor is used to capture pressure data. A circuit uses the pressure data to compensate the electrodermal activity, thus improving accuracy.
