Shimmer Research has launched Verisense Pulse+, a new sensor for the Verisense platform. Verisense Pulse+ provides photoplethysmogram, galvanic skin response (GSR), and an inertial measurement unit. The Verisense platform can now measure clinical trial participants’ heart rate, oxygen saturation and emotional responses in addition to their activity and sleep levels.
The PPG sensor monitors heart rate by using light absorption to measure changes in participant capillary blood volume. Whereas the GSR sensor measures changes in sweat gland activity, which can be used to assess the participant’s level of psychological and emotional arousal, stress, and other emotional responses.
