“The ink, pattern, and saturation of some tattoos can block light from the sensor, making it difficult to get reliable readings. “Permanent or temporary changes to your skin, such as some tattoos, can also impact heart rate sensor performance,” the help page now reads. In this purpose, we developed a new aerogel-based nano-tattoo that acquires robust heart rate signals directly from the wrist, while reliably detecting AF, during extreme upper extremity motions, such as arm swing, repetitive elbow flexion/extension, waving, etc., using artificial intelligence based neural networks.

Update: On Friday Apple updated its support documents for Apple Watch to include information about tattoos potentially interfering with the device. The heart lock and key tattoo design below looks quite reinforced on the body with the beautiful flowers enhancing the entire look of the whole designThe place the tattoo is worn demonstrates the value of how the heart is protected from any outside intrusion. Potential buyers who sport ink should probably test the watch at an Apple Store before purchasing.
#Heart monitor tattoo skin
Natural skin pigments don’t seem to cause the same issue, but other things like scars might.Īpple acknowledges in its support article that “various factors” could make it impossible for a small subset of users to get a heart rate reading, but the company doesn’t specify what those factors are. In particular, tattoos that make use of dark colors could make the heart rate monitoring feature yield faulty results. The tech news site tried to replicate some of the complaints using tattooed and non-tattooed wrists.
The presence of artificial ink on the skin can apparently interfere with this process, according to iMore, by reducing the Apple Watch sensor’s ability to detect changes in light. Lu and her team are already working on improvements to data collection. This device can be worn for days, providing constant heart monitoring. Usually an ECG measurement requires going into a doctors office, where heart health can be monitored only for a couple of minutes at a time. By flashing its LED lights hundreds of times per second, Apple Watch can calculate the number of times the heart beats each minute - your heart rate. The e-tattoo has another advantage over traditional methods.
When your heart beats, the blood flow in your wrist - and the green light absorption - is greater. Apple explains the process in a support article for the watch:Īpple Watch uses green LED lights paired with light‑sensitive photodiodes to detect the amount of blood flowing through your wrist at any given moment.
