Austin, Texas-based Biostrap designed its device to quantify data from the sympathetic and parasympathetic branches through a wrist-worn device. The company says researchers could only access such measurements through electrocardiogram chest straps.
The wrist-worn device includes a modular design allowing for positioning on the forearm or bicep. It utilizes a high-sensitivity, complementary metal-oxide-semiconductor (CMOS) optical sensor. This captures raw photoplethysmography (PPG) data. With this data, Kairos computes biometrics such as active and resting heart rate, HRV, beat-to-beat intervals and respiratory rate. It also measures sleep-releated parameters, according to a news release
