## Interventions

- **wearable vital signs sensor** (DEVICE) — vital signs monitoring during maternal non-stress testing

## Primary Outcomes

- **Device comparison to standard monitoring** _(time frame: 3 years)_ — The primary outcome measure is concordance of FHR tracing assessments from Rogers sensor recordings with those obtained from the current standard of care electronic fetal monitoring systems.

## Secondary Outcomes

- **Qualitative analyses of sensor output** _(time frame: 3 years)_
