Los Angeles, CA-- April 17, 2006—Material Technologies, Inc. (OTC BB; MTNA.OB - News) ("MATECH") announced that it has just completed an inspection of a bridge across Balloona Creek in Culver City, California.

The goal of this inspection was to further refine its inspection techniques using its proprietary Electrochemical Fatigue Sensor (EFS) technology, and verify performance of the latest version of its potentiostats, the electronic assemblies that provide the constant voltage to energize the EFS and submit their fatigue signal measurements wirelessly to a nearby computer. These potentiostats are a proprietary design produced for Matech by Pinnacle Technology Inc. of Lawrence, Kansas.

“This test demonstrated that the potentiostats met all our requirements,” said Robert M. Bernstein, CEO of Material Technologies, Inc. “It will enhance our ability to conduct future EFS inspections more efficiently and faster, thereby reducing the cost of EFS inspections.” A video was also made of the inspection operations, for use in future marketing efforts.

The EFS is the only non-destructive testing technology that can find growing cracks in metals, and cracks below the surface, as small as 0.010 inches. This critical information will allow bridge engineers to fix the specific bridges in most need of repair, and also verify that repairs are effective in halting further fatigue crack growth, by determining that previously found fatigue cracks are no longer growing. Being able to prioritize needed repairs by using EFS, significant cost savings can be realized, and the most critical bridges can be repaired sooner, thereby eliminating bridge postings (that is, restricting the weights of some trucks) and minimizing any adverse economic impacts.

"We expect many more states to approach us this year and we look forward to using our EFS technology to help them to greatly improve their success ratio in focusing repairs on the most structurally damaged bridges," says Robert M. Bernstein, the CEO of Material Technologies, Inc. "This is a very exciting time for us and the bridge industry, as we believe that our patented technology will make a significant contribution to the safety and integrity of the nation's 200,000 metal bridges that come under the Federal inspection mandate."

Interest in MATECH's EFS system has been spurred by the recent $286 billion Federal Transportation Bill which allocated $5 million to help states evaluate nondestructive methods such as EFS to test growing fatigue cracks in steel bridges. The nation's aging bridge infrastructure system is a major cause for concern, with more than 100,000 of the 200,000 steel bridges in the U.S. classified as structurally deficient or functionally obsolete, according to the Federal Highway Administration (FHWA).

MATECH is engaged in the research and development of metal fatigue detection, measurement, and monitoring technologies. As such, the Company has developed a suite of devices for the non-destructive testing of metal fatigue and monitoring of structural integrity. These technologies can be applied in virtually any industry in which metal is a significant structural component; i.e.: Bridges, Aerospace, Railroad, Oil & Gas, Construction, Shipping, etc.
