Concerns are rising over the safety of smartwatch bands after a new study identified the presence of hazardous chemicals in these popular accessories.
What Happened: A recent study published in the journal Environmental Science & Technology Letters has discovered that smart watch bands may contain harmful substances. These bands, often made from synthetic rubber known as fluoroelastomers, can include perfluorohexanoic acid (PFHxA), a type of “forever chemical,” Salon reported on Thursday,
PFHxA is part of a group of industrial compounds called per and polyfluoroalkyl substances (PFAS), which are resistant to degradation. These chemicals have been associated with serious health issues, including cancer and infertility. Despite the risks, PFAS are commonly found in various consumer products such as non-stick cookware and water-resistant fabrics.
The study, led by Graham F. Peaslee from the University of Notre Dame, analyzed 22 watch bands from different brands and price ranges. Surprisingly, PFHxA was the most frequently detected compound. Peaslee noted that the public might not recognize fluoroelastomers as a type of PFAS, leading to unintentional exposure.
Although the study did not involve human testing, the researchers warned that high PFAS levels in these bands could lead to significant skin absorption, especially during activities involving sweat and open pores.
Why It Matters: The revelation of toxic chemicals in smart watch bands comes at a time when the global wrist-worn device market is experiencing significant growth. Chinese tech giants are challenging the dominance of established players like Apple Inc. AAPL. The global market saw shipments reach 139 million units in the first three quarters of 2024, with China leading the charge.
Additionally, Samsung Electronics Co Ltd SSNLF is intensifying its competition with Apple by launching new wearables, including the Galaxy Ring and Watch Ultra. As the market expands, the potential health risks associated with PFAS in smart watch bands could become a significant concern for consumers and manufacturers alike.
