Perminova is developing a necklace for clinical use that can track a number of vital signs including thoracic fluid
levels, an early predictor of congestive heart failure that isn’t currently monitored by most connected sensors. Patients at risk for CHF could use the device in place of or along with a weight scale.
The system, called the CoVa monitoring system, is a large decorative necklace, with adhesive on the back of it, which patients are instructed to wear for a few minutes once a day. It sends a Bluetooth signal to either an Android tablet or a Qualcomm Life 2net Hub, which then sends the data to the cloud via cellular or WiFi. Sensors in the device track fluid levels, heart rate, respiration rate, heart rate variability, stroke volume, cardiac output, single-lead ECG, and posture.
“We’re trying to do for congestive heart failure what a glucometer does for diabetics,” Susan Pede said from Perminova. “We’ve talked a lot about congestive heart failure, but we have had some interest from other industries, in terms of a low acuity necklace for stroke monitoring.”
It might seem odd to have a wearable, fashion-forward device for a brief, daily check-up. But Pede says the necklace form factor both allows the company to be flexible in the development of future use cases and makes it easier to ensure consistent placement of the electrode.
