description: "A new study reveals that wearable health devices could generate over a million tons of e-waste by 2050, as demand may reach 2 billion units annually. The study highlights that the printed circuit board contributes 70% of the carbon footprint, primarily due to mining and manufacturing. Researchers recommend using common metals like copper and designing modular devices to mitigate environmental impact. This issue is notably absent from discussions at CES 2026, where new health gadgets are being showcased."

# Wearable health devices could generate a million tons of e-waste by 2050

This week in Las Vegas, tech companies at CES 2026 are unveiling the latest wearable health devices — glucose monitors, blood pressure trackers, fitness trackers. Probably _not_ mentioned at the show is that these gadgets might be creating a massive environmental problem.

It isn’t something that tends to get much attention but a new study from Cornell University and the University of Chicago found that by 2050, demand for health wearables could hit 2 billion units per year, or 42 times more than today. Unless we change how they’re made, these devices could generate over a million tons of electronic waste and 100 million tons of carbon dioxide over that same period, the authors warn.

An even bigger surprise is that it’s not the plastic that’s the problem. The study, published in Nature, found that the printed circuit board — the device’s “brain” — accounts for 70% of its carbon footprint largely due to intensive mining and manufacturing.

The researchers suggest two fixes: develop chips using common metals like copper instead of rare minerals like gold, and make devices modular so the circuit board can be reused while the outer covering gets replaced.

Wrote one of the study’s co-authors, “When these devices are deployed at global scale, small design choices add up quickly.” It’s something to think about while scrolling through CES announcements.
