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
Biostrap says its Kairos system features a comprehensive stress resilience measurement, too. It allows users to understand the extent to which they are in fight-or-flight or rest-and-digest mode. The system tracks this throughout the day and in real-time.
“We are thrilled to launch Kairos and our new Spot Check feature,” Sameer Sontakey, Biostrap CEO and co-founder said. “Our dedicated team has worked tirelessly to create this cutting-edge culmination of hardware and software that positions Biostrap as the leader in quantifying clinical-grade heart rate variability (HRV) parameters and providing researchers and healthtech visionaries invaluable insights into their patients’ and clients’ autonomic nervous system like never before.”

The system also utilizes technology from Ambiq to offer strong battery life and syncing speeds.
According to Biostrap, its commitment centers around delivering clinically reliable nervous system analysis through detailed and transparent biometric measurements. It enables real-time visualization of the underlying PPG signal on which the biometrics are derived. With visualization of signal quality and R-R intervals, Biostrap provides access to a wide range of data points.
Prior to its official launch, Kairos underwent “extensive testing” in heart rate variability research. Data scientist Marco Altini compared Kairos against an ECG chest strap heart rate monitor for assessing accuracy levels.
This launch marks Biostrap’s official pivot to exit the consumer wearable market. The company aims to move into configurable hardware and software for enterprise and research purposes.
