Printed sensor made to warn of worn tires

The sensor incorporates two adjacent electrodes, seen here between the logos of Duke University and the Fetch Automotive Design Group While there are already systems that estimate tire wear, electrical engineers at Duke University have developed a sensor that actually measures it in real time. Designed in collaboration with the Fetch Automotive Design Group, the relatively simple device can reportedly track millimeter-scale changes in tread depth with 99 percent accuracy. The sensor is adhered to the inside wall of a tire, and consists of two electrodes made of carbon nanotubes. Those electrodes are printed very close to one another […]
