Duke University electrical engineers have developed a printed sensor that can monitor the tread of car tyres in real time. The group thinks that the tyre wear sensor could disrupt the $2 billion tyre and wheel control sensor market. In collaboration with Fetch Automotive Design Group, the Duke researchers have demonstrated a design using metallic carbon nanotubes (tiny cylinders of carbon atoms just one-billionth of a metre in diameter) that can track millimetre-scale changes in tread depth with 99 per cent accuracy. The design has two patents pending.
