Wearable fitness trackers and smartwatches often struggle to accurately read heart rate and detect wrist presence for individuals with tattoos. The tattoo ink can interfere with the light-based sensors (photoplethysmography or PPG) used for these measurements. Device manufacturers like Garmin Ltd. and Apple Inc. have acknowledged this issue, advising users to wear devices on un-tattooed skin if possible. While workarounds like repositioning the device, using tape, or employing chest straps exist, they are not always ideal, highlighting a need for improved sensor technology that accounts for skin variations.
