More sensors to be added to Michigan’s Mackinac Bridge for maintenance experiment

Thousands more tiny sensors will soon be installed on the Mackinac Bridge in Michigan to gather data in a project that could lead to better, lower-cost bridge maintenance and management.

The project began in 2016 with 20 prototype sensors placed on the bridge. And about 2,000 more are scheduled to be installed this summer, MSU Today reports.

The sensors, part of a research project by Michigan State University and Washington University in St. Louis, is being tested as a low-cost alternative to monitoring a bridge’s conditions. The sensors are powered by traffic vibrations and do not need batteries or wires.
