Dissolvable Memristor

Since 1971, electrical engineers have sought to understand the concept of “memristor”—i. e. a circuit that can do two things, regulate the flow of current, and “remember” changes. A memristor switch could be a more precise way of delivering, say, insulin or chemotherapeutics. And, an implantable memristor made of dissolvable components could be an ideal drug delivery device which did not need to be retrieved from the body. British and Chinese researchers believe they have such a platform, with magnesium and titanium electrodes affixed to a silicon substrate coated with egg albumin. In water tests, the electrodes and albumin dissolved in in ten hours, while the silicon broke down in about three days.   MORE
