Health tech startup WearLinq has announced eWave. It is dubbed as the world’s smallest, lightest, and first 24/7 ECG wearable made with stretchable sensors.

eWave is a medical-grade monitor that records a 6-lead ECG and transmit it in real time to your phone to detect irregular heart rhythms. It was developed at the world-leading lab on stretchable electronics at Stanford University.

We’ve already seen smartwatches with ECG sensors. Apple Watch is the first one that springs to mind, but there are others. One of the things that makes eWave different is that it offers continuous ECG monitoring. Others typically provide 30 second on-demand snippets which while useful can miss episodes of arrhythmia.

Battery life is about 3 days on a single charge which means you can have that those many days of uninterrupted readings. There’s also a charging case which is useful on the go as it can provide 12 days worth of monitoring.

The company says the device is capable of identifying Atrial Fibrillation, Bradycardia, Tachycardia and normal heart rhythm. If there’s something amiss, there’s an accompanying smartphone app that allows users to directly connect with physicians and schedule same-week cardiologist e-visits. This reduces the typical 4 month period of onset of symptoms to diagnosis to just two weeks.

The other advantage of using eWave is the fact that it has 6-leads which provides more accuracy than ECG sensors that can be found in smartwatches. And the device is very light (5.4 grams) and small (3.3cm x 2.4cm x 0.8cm).

To use you are meant to stick the eWave on your chest like a bandaid. It comes with stretchable electronics which are splash-proof. This means you can take a shower with the thing on but don’t plan on taking a bath. Each patch lasts about a week and you get 25 patches in a box. After launch you’ll be able to order more at $2 a pop.

eWave has just launched on Indiegogo and with 30 days left is about half way there towards its funding goal. If you want in it will cost you $179. The wait is quite long for delivery as the wearable is expected to ship in May 2021. Part of the delay may be the fact that the company will need FDA approval before shipping the device.
