It’s now a well-known fact that the wrist isn’t the best place for fitness tracking. Between most devices unable to know the difference between walking and typing and the inaccurate relationship between steps taken and calories burned most rely on, this isn’t entirely surprising.
Instead of relying on the limited information supplied by the wrist, Kenzen’s ECHO H2 uses a person’s own sweat to more accurately glean all sorts of information from the body, from heart rate to calorie intake and burn. Since the measurements are based on biochemical processes, the results are way more accurate; it’s like having a lab nearby at all times.
The ECHO H2 is notable because it takes the form of a wireless smart patch that uses medical grade adhesive to comfortably stick to a person’s calf or abdomen for up to a week straight. Over this time, it continuously monitors aspects of the body’s functions, alerting users with buzzes and sounds when they should ease up to avoid overtraining.
Although it uses Bluetooth LE to connect with a smartphone, it fortunately isn’t necessary to bring one along, a death knell to a lot of other fitness trackers. The ECHO H2 itself stores data that later can be synced with the robust mobile app, which offers capabilities like custom notifications, reporting, and team tracking. For $89, backers will receive 20 reusable and disposable patches along with a fully unlocked mobile app, expected to ship on July 2015. The campaign is looking for $75,000.
The ECHO H2 is extremely similar to the LEO in that they both keep an eye on user’s activity through sweat, but the LEO is a lot bigger than the tiny ECHO H2. With the LEO being reusable, though, it bodes much better for the environment when compared to the ECHO H2’s disposable nature. Both are technologically impressive, and gym rats and fitness freaks will be interested.
