The Verisense Pulse+ can measure heart rate, oxygen saturation, emotional responses, and activity and sleep levels of at-home clinical trial participants.
Shimmer Research has announced its Verisense Pulse+ sensor for use with its Verisense wearable sensor platform. The device is designed to offer photoplethysmogram (PPG), galvanic skin response (GSR), and inertial measurement unit (IMU).
According to the company, the PPG sensor monitors heart rate by using light absorption to measure changes in capillary blood volume. The GSR sensor measures changes in sweat-gland activity; this can be used to gauge the patient’s level of psychological and emotional arousal, stress, and other responses; GSR typically is employed in psychological research and biofeedback, and it is started to be used in more clinical applications, such as epilepsy.
