How itchy are you? A new device knows precisely

You may have been asked by a doctor to rate your pain on a scale of one to ten, but have you ever been asked to rate your itchiness? A team of US researchers have developed a device that records scratching, allowing them to measure the itch people feel.

“Itch torments so many patients across so many conditions. It can be as debilitating as chronic pain,” says Shuai Xu, assistant professor of dermatology and paediatrics at Northwestern University Feinberg School of Medicine, US.
