Natrium develops a wearable biosensor patch that continuously measures sodium levels in interstitial fluid, delivering real‑time data to clinicians via Bluetooth‑enabled mobile or EHR interfaces. By providing trend and rate information rather than isolated lab draws, the device aims to enable proactive treatment for patients with hyponatremia in settings such as oncology, heart failure, and intensive care.

Problem
Hyponatremia affects a large proportion of hospitalized patients, especially those with oncology, heart failure, or chronic kidney disease, and current monitoring relies on intermittent lab draws that delay detection of dangerous sodium shifts.
Solution
Natrium offers a wearable upper‑arm patch that continuously samples interstitial fluid and measures sodium concentration with ion‑selective electrodes. The sensor transmits real‑time readings via low‑power Bluetooth to a mobile application or directly to an electronic health record, allowing clinicians to view sodium trends and rates of change rather than isolated lab values. By providing near‑continuous data, the platform enables earlier therapeutic adjustments for fluid and medication management, aiming to reduce mortality, length of stay, and associated costs. The system is designed for multi‑day wear in both clinical and ambulatory settings and can be expanded to monitor additional electrolytes such as potassium and chloride.
Target Audience
Primary users are clinicians managing patients at risk for hyponatremia, including oncologists, cardiologists, nephrologists, and intensive‑care teams, as well as outpatient providers monitoring chronic heart‑failure or kidney‑disease patients.
Features
- Upper‑arm wearable patch with a low‑profile, multi‑day adhesive design
- Minimally invasive interstitial fluid access for continuous sampling
- Ion‑selective electrodes delivering sodium measurements with <5% deviation from laboratory reference
- Low‑power Bluetooth module that streams data to a smartphone app or EHR in real time
- Mobile and clinician dashboards that display sodium trends, direction, and rate of change
- Architecture capable of adding sensors for other electrolytes (e.g., potassium, chloride)
