Los Angeles, CA - March 18, 2007 -- Material Technologies, Inc. (OTC BB; MTTG.OB - News) ("MATECH" or "the Company"), announced that the Massachusetts Department of Transportation (MADOT) intends to invite MATECH to demonstrate its Electrochemical Fatigue Sensor System (EFS) on several bridges around the State.

Last year MADOT sent MATECH information on seventeen bridges around the State, with the intention of having MATECH demonstrate its EFS on many of these structures. However, critical problems with their “Big Dig” tunnels created a large demand on MADOT’s resources, so the EFS efforts had to be postponed.

MATECH CEO Robert M. Bernstein commented: "Now being in the state of commercialization, we are extremely pleased to demonstrate our EFS to the MADOT. I am confident that the EFS will help the State to detect growing cracks in their steel bridges, greatly increasing their transportation infrastructure safety and to realize cost savings in their bridge maintenance budgets."

The EFS can find growing cracks in highway bridges and similar structures, including cracks below the surface, as small as 0.01 inches. This critical information allows the State’s bridge engineers to fix the specific bridges in most need of repair. Using EFS, the engineers will also be able to verify that repairs are effective in halting further fatigue crack growth, by determining that previously repaired fatigue cracks are no longer growing. Being able to prioritize needed repairs, the State can realize significant cost savings. It can also repair the most critical bridges sooner, thereby eliminating the need to restrict the weights of some trucks and, most important, minimizing any adverse economic impacts.

MATECH has received a great deal of interest from federal and state agencies, following the passage of the $286 billion Federal Transportation Bill, which included funds to help states evaluate nondestructive methods such as EFS to detect growing fatigue cracks in steel bridges.

About Material Technologies, Inc. (MTTG.OB)

MATECH is an engineering, research and development company specializing in technologies to measure microscopic fractures and flaws in metal structures and monitor metal fatigue in real time. The company’s leading edge metal fatigue detection, measurement and monitoring solutions can accurately test the integrity of metal structures and equipment including bridges, railroads, airplanes, ships, cranes, power plants, mining equipment, piping systems and heavy iron.

MATECH owns the only non-destructive testing technology able to find growing cracks as minute as 0.01 inches—critical information that allows structural engineers to isolate and repair the more than 100,000 steel bridges in the U.S. which have been classified as structurally deficient or functionally obsolete by the Federal Highway Administration. MATECH has exclusive rights to seven patents along with $8.3 million in already completed contracts from the US Government for research, testing and validation of its innovative solutions.
