Biostrap

Biostrap is a company that provides scalable and customizable biosensor-based precision health monitoring solutions. Their innovative wearable devices, such as the Biostrap Kairos launched in July 2023, offer advanced autonomic nervous system analysis and quantification of the sympathetic and parasympathetic branches through wrist-worn devices. Kairos utilizes a high-sensitivity CMOS optical sensor to capture raw photoplethysmography (PPG) data, enabling accurate computation of biometrics like heart rate, heart rate variability (HRV), beat-to-beat intervals, respiratory rate, and sleep-related parameters.

Biostrap's key differentiator lies in its commitment to delivering clinically reliable nervous system analysis through detailed and transparent biometric measurements. The Spot Check feature provides real-time visualization of the underlying PPG signal, signal quality, and R-R intervals, granting untethered access to every data point captured. This configurability and data integrity attracted clients like the National Police Wellbeing Service (NPWS) in the UK for their sleep, fatigue, and recovery program.

Kairos underwent extensive testing by HRV experts and achieved impressive accuracy levels, comparable to ECG chest straps. The launch marked Biostrap's pivot from the consumer wearable market to offering configurable hardware and software solutions for enterprise and research purposes.
