Chinese team’s wearable dopamine patch could be used to track depression, Parkinson’s

Scientists in northeast China say they have developed a “rapid and ultrasensitive” dopamine-sensor" class="entity-link entity-topic" data-entity-id="163495" data-entity-type="topic">wearable dopamine sensor to monitor levels of the critical neurotransmitter.The smart patch could potentially be used for at-home tracking of conditions such as Parkinson’s disease and depression, according to the research team from the Chinese Academy of Sciences’ Shenyang Institute of Automation.They said the patch – which uses microscopic needles to test fluid just beneath the skin – was painless and monitored dopamine levels in real time.
