ActiGraph’s newest device, ActiGraph LEAP, can collect physiological signals in addition to movement data, which can provide enriched information about sleep and circadian rhythm beyond simple actigraphy devices like the discontinued Philips Actiwatch, according to Actigraph CEO Jeremy Wyatt. “With the photoplethysmogram sensor on LEAP, we can provide sleep staging, monitor skin temperature, respiration, and oxygen saturation during sleep,” he says.

The new ActiGraph LEAP device is equipped with multi-sensor technology and provides a wide spectrum of health metrics from a single wrist-worn device. “Beyond the simple sleep/wake detection provided by actigraphy devices like Actiwatch, it can provide sleep staging, vital sign monitoring, gait assessment, and so on,” Wyatt. Says. “Furthermore, we always provide raw data from our devices which is critical for research transparency and longevity.”
