Making the internet of things possible with a new breed of ‘memristors’

Easily printable, organic thin films can retain data for more than 10 years without power, work with low voltages — and become the building block of future computers that mimic the human brain

The internet of things is coming, that much we know. But still it won’t; not until we have components and chips that can handle the explosion of data that comes with IoT. In 2020, there will already be 50 billion industrial internet sensors in place all around us. A single autonomous device — a smart watch, a cleaning robot, or a driverless car — can produce gigabytes of data each day, whereas an airbus may have over 10,000 sensors in one wing alone.
