Withings isn’t a stranger to good scales, however for CES 2022 the corporate is taking a far more formidable tackle the gadget. Announced right this moment, the Withings Body Scan will function six-lead EKG readings, segmented body composition measurements, and the power to evaluate foot nerve exercise. Basically, it’s the scale for individuals who need to know the way fats is distributed by way of their body and how that may in flip relate to their coronary heart well being.

On the floor, the Body Scan appears to be like like your typical scale — albeit with a retractable handle up high. It accommodates 4 weight sensors and 14 ITO electrodes within the scale itself, plus a further 4 situated within the handle. The scale additionally options a bigger 3.2-inch LCD shade display, in addition to a battery life of 1 12 months. It’ll additionally combine with Withings’ smartwatches, on high of Apple HealthKit and Google Fit APIs.

While the handle is certainly distinctive visually, it’s additionally what allows the Body Scan’s extra fascinating options. Smart scales measure body composition through bioelectrical impedance evaluation (BIA). It works by sending a low-level electrical present by way of your body. Body fats, water, and lean mass all have completely different resistance ranges, so relying on the speed at which the present travels, the scale will estimate your body composition. However, most scales solely have two factors of contact: your ft. That means you’re actually getting an estimate for your decrease body solely. Withings says the Body Scan will use “multi-frequency” BIA because the retractable handle gives two additional factors of contact, therefore, segmented body composition measurements.

Withings claims the Body Scan can differentiate between your torso, your proper and left legs, and your proper and left arms. The scale may even break down body composition into whole-body fats and water percentages, visceral fats, muscle and bone mass, and extracellular and intracellular water. It’s laborious to say how correct the Body Scan might be — good scales are notoriously inaccurate — however it’s admittedly good to see that Withings is trying to offer additional context. For instance, many good scales don’t differentiate between subcutaneous and visceral fats. While jiggly subcutaneous fats is comparatively innocent, invisible visceral fats is the type that’s really most harmful to your well being.

Body composition has had a current resurgence in wearables. Samsung launched BIA evaluation on its Samsung Galaxy Watch 4, whereas Amazon additionally launched a body fats function on its Halo platform. Each of those firms has emphasised their body fats instruments as a substitute for Body Mass Index (BMI), which is a flawed metric for evaluating your total well being. That stated, improperly monitoring body fats also can act as a potential set off for body dysmorphia and different consuming issues.

The Body Scan will retail for $279 and are available in black and white.

“We’ve been looking for a way to do this safely and effectively,” Withings chief medical officer Shikha Anand advised The Verge. “We can’t solve the way in which the world sees weight, but that said, we will make every effort not to exacerbate it. We will ground in health and not in weight wherever we can. It will always be about how your weight relates to your health.”

Anand went on to clarify that weight is commonly tied to vanity, and that’s a part of why Withings needs to repackage its scale as a well being station. The concept, Anand says, is to indicate how your weight relates in context to your total cardiovascular well being, in addition to provide extra holistic, behavioral insights. Anand additionally emphasised Withings is testing the Body Scan with a various cohort of customers to make sure the body composition function is extra useful than dangerous. She additionally stated the Withings app can be upgraded with higher information visualizations for long-term traits.

Aside from body composition, Withings says the Body Scan will present coronary heart charge, EKG recordings, and vascular age information at every weigh-in. EKG readings might be saved and shared with docs. Meanwhile, the vascular age function is supposed to indicate folks how their cardiovascular well being compares to different folks inside their age group.

While body composition, and even EKGs, make sense for a scale, Withings is taking it one step additional with a new nerve evaluation function developed with French medical machine maker Impeto Medical. The scale will purportedly measure sweat gland exercise in your ft and generate a rating. According to Withings, foot nerve exercise is at present below investigational use and may doubtlessly present indicators of nerve dysfunction.

This is all effectively and good, however like Withings’ different current devices, the Body Scan is topic to FDA and CE clearance. So whereas Withings says it plans to launch the Body Scan for $279 within the second half of 2022, that’ll all rely upon how briskly the corporate can get the regulatory go-ahead. The Withing ScanWatch, as an illustration, was introduced at CES 2020 and solely obtained FDA clearance in November 2021. Despite this, Anand says Withings is optimistic it gained’t take fairly as lengthy this time round.

“We’ve learned a lot with the process of the ScanWatch, and gotten to know the team at the FDA quite a bit better. I feel we’re on the path to have [the Body Scan] on a reasonable time frame.”
