New York, April 11: Scientists have come up with a novel tiny, ultra-low power chip that can be injected just under the surface of the skin to continuously monitor patients of substance abuse. The chip can be powered wirelessly by a wearable device such as a smartwatch.

“A tiny injectable sensor — that can be administered in a clinic without surgery — could make it easier for patients to follow a prescribed course of monitoring for extended periods of time,” said lead author Drew Hall, Professor at the University of California-San Diego. The new bio-sensor chip measures roughly one cubic millimetre in size and can be injected under the skin in interstitial fluid — the fluid that surrounds the body’s cells. It contains a sensor that is coated with alcohol oxidase, an enzyme that selectively interacts with alcohol to generate a byproduct that can be electrochemically detected. The electrical sigls are transmitted wirelessly to a nearby wearable device such as a smartwatch, which also wirelessly powers the chip. (IANS)
