We offer solutions and insights to make these coexist.
1. How Do Tattoos Interfere With Smartwatch Functionality?
Tattoos can interfere with smartwatch functionality, primarily due to the technology these devices use to monitor your health metrics. Most smartwatches rely on photoplethysmography (PPG) sensors, which use light to measure heart rate and other vital data.
1.1. The Science Behind PPG Sensors and Tattoo Interference
PPG sensors work by shining light into your skin and measuring the amount of light reflected back. This reflected light helps the device determine your heart rate, blood oxygen levels, and other health metrics. However, darker colors, including dark tattoo ink, absorb more light and reflect less, which can disrupt the sensor’s ability to accurately read your biometric data. According to research from Portland State University’s Art Department, dense tattoo designs and darker inks are most likely to cause interference with PPG sensors.
1.2. Specific Issues Caused by Tattoos
- Inaccurate Heart Rate Readings: Tattoos can cause your smartwatch to provide incorrect or inconsistent heart rate readings.
