A 2-gram wearable thermometer with medical-grade ±0.2°C accuracy, recording every 5 seconds for 7 days — a patient temperature monitoring system that scales from one feverish child at home to an entire hospital ward on one dashboard.
What it does, how accurate it is, and where the same sensor is already running.
Compared with a conventional thermometer, OnCorva does not capture a single reading and stop. The 2g wearable sensor stays under the arm and records body temperature every 5 seconds for up to 7 days, turning fever changes into a continuous curve. Caregivers can see when the fever started, how fast it is rising, whether medication is working, and whether the temperature is truly coming down or only dipping between spikes.
OnCorva is a Class II medical device with clinically validated ±0.2°C accuracy and 0.01°C resolution. Each sensor is calibrated before shipment, then worn under the arm with a hypoallergenic medical patch. The lightweight 2g design is suitable for babies, elderly users and patients who need repeated temperature observation without being disturbed.
The same OnCorva sensor works with a family app, a bedside terminal or Bluetooth gateways connected to a nurse dashboard. Families can watch one feverish child at home; hospitals and care facilities can monitor multiple beds from one screen. For distributors and OEM partners, it means one wearable thermometer platform for retail, clinical and institutional channels.
Every OnCorva deployment starts with the same 2g sensor. What changes is who's watching: a parent's phone, a bedside display, or a nurse console covering a whole ward.
Sticks under the arm with a hypoallergenic patch. Records every 5 seconds, runs 7 days on a coin battery, weighs just 2 grams.

Yes. The 2g sensor attaches under the arm with a hypoallergenic medical-grade patch and is designed for multi-day wear. It is suitable for baby fever monitoring, child fever monitoring, elderly care and patients who need repeated temperature observation without being woken for manual checks.
Mercury thermometers, infrared forehead thermometers and ear thermometers provide one reading at one moment. OnCorva records body temperature every 5 seconds, shows the fever curve and supports alerts, so caregivers can see trends, overnight spikes and post-medication changes instead of relying on isolated spot checks.
