Soft wearable sensors to detect developmental disabilities in kids

Children who’re born prematurely are usually more susceptible to neuromotor and cognitive developmental disabilities. The easiest way to reduce its impact is to catch them early on with a series of cognitive and motor tests. But accurately detecting these abnormalities in kids can be a little tricky.

Scientists have developed a soft, non-toxic wearable sensor that can be attached to the hand to monitor force of a grasp and the motion of the fingers. This sensor isn’t bulky and doesn’t cause discomfort to the wearer, making it perfect for young children.

Instead of a bulky glove or device, this sensor is a little silicone-rubber sensor that sits on top of a finger or finger pad. The sensor contains a sensory liquid, which gives a result accurately and without any hassle.

“We have developed a new type of conductive liquid that is no more dangerous than a small drop of salt water. It is four times more conductive than previous biocompatible solutions, leading to a cleaner, less noisy data,” said Siyi Xu, a graduate student at Harvard University in the US.

This device can be easily be stuck on the top of the finger to give accurate information while taking care of the sensitivity of the child. However, despite the advanced nature of this technology, application for it is still limited
