From the Wrist into the Ear

In her article, Mareike Scholze writes, "Progress in miniaturizing sensor technology has opened up new possibilities for monitoring vital signs outside the hospital environment. A subset of wearables is the so-called hearables – in-ear devices that are well suited for long-term monitoring as they are non-invasive, inconspicuous, and easy to fasten. Hearables offer two major benefits: their proximity to the torso and vascular system of the brain and ear is a physiological advantage and motion artifacts often seen with wrist wearables are no longer an issue for in-ear devices."
