The need to effectively monitor the structural health has increased since structural failure could be devastating to our society and economy.


Almost 40% of the 614,387 bridges in U.S. are 50 years or older and 56,007 (9.1%) of them are structurally deficient with a C+ overall rating for safety. 188 million daily trips occur on these structural deficient US bridges and 1,900 of them are on the interstate highway system. An estimated cost of $123 billion is required to rehabilitate them.

In addition to infrastructure, aging and newly-built large-scale structures for energy and traffic uses are also in great need of reliable, accurate and rapid structural monitoring.

The structural health monitoring of infrastructure has rapidly grown across the globe with a total available market size of ~$1.35 billion and an annual growth rate of ~20%. North America is contributing the highest share (35%) in terms of revenue followed by Asia-Pacific’s 25%.
