After an ICU stay and diagnosis of diabetes insipidus, John Stallings co-founded Natrium to develop a wearable biosensor that continuously monitors sodium. Its investigational Natrium ONE patch is designed to track sodium in interstitial fluid and show clinicians the current reading, trend, and rate of change rather than relying only on periodic lab draws. Founded in 2024, the founder-led company is developing the device for high-risk clinical settings with co-founder and CTO Andrew Mancini, PhD, the architecture’s lead inventor.
One Health BiosensingOne Health Biosensing is developing an intradermal continuous glucose monitoring system built around a microneedle sensing platform that sits in the skin without piercing it. Its design pairs a reusable battery pod with a daily disposable sensor to lower costs and reduce medical waste, while AI-enabled guidance is intended to help people with type 2 diabetes act on their glucose data. The sensor remains investigational and has not been approved or cleared by the FDA.
Illumination DiagnosticsIllumination Diagnostics grew from a collaboration between neurosurgeon Theodore Schwartz and electrical engineer John Kymissis, who designed a device around the needs they saw in patient care. The Scarsdale company’s team brings more than 50 years of combined experience across medicine, neuroscience, engineering, and entrepreneurship to wearable optical monitoring for clinical and at-home use.SCARSDALE, NY
Neurosteer IncFounded in 2015 by Tel Aviv University professor Nathan Intrator, Neurosteer develops a wearable, medical-grade brain-activity interpretation platform built around a pocket-sized, single-channel EEG monitor. Its wireless forehead sensor and cloud-based analysis provide real-time brain metrics for clinical assessment, continuous monitoring and research, and the device has FDA Class II clearance. Neurosteer’s teams work across New York, California and Israel, drawing on expertise in neuroscience and signal processing.NEW YORK, NY
Advanced Biomimetic Sensors, IncFounded in 2006 by CEO Ellen T. Chen, Ph.D., Bethesda-based Advanced Biomimetic Sensors is a woman-owned small business developing medical diagnostic and monitoring devices built around nanobiomimetic, reagent-free sensing. Its work includes handheld systems for triple-negative breast cancer monitoring and blood-glucose testing, alongside the patented QSensing® platform for detecting proteins in human serum. The company’s technology has received National Innovation Awards in 2017 and 2018 and a National Defense Innovation Award in 2022.BETHESDA, MD
