Los Angeles, CA - May 14, 2007 -- In March, 2007, Material Technologies, Inc. ("MATECH" or "the Company") (OTC BB; MTTG.OB - News) Director of Marketing, Dr. Brent Phares, PE, was invited to give the keynote address at the 2007 China Bridge Congress. During that address, Dr. Phares highlighted both the safety and economic advantages of implementing MATECH’s Electrochemical Fatigue Sensor (EFS).  Attending the Congress were representatives from both private and public entities.  Although heavily attended by Chinese engineers and administrators, representatives from Japan, South Korea, and throughout Europe were in attendance.

Since the Congress was completed, MATECH has received a significant number of inquiries about its technology.  Currently, MATECH is in discussions with various organizations about completing demonstration-type projects.  Further, Dr. Phares, reknowned bridge engineering expert, has been invited back to China to provide further technical information.  In May, 2007 Dr. Phares will be again meeting with representatives from throughout China.

"MATECH is very pleased, but not surprised, with the interest in China and elsewhere." said MATECH CEO Robert M. Bernstein. "With the significant amount of infrastructure being built in China, there is no doubt that they will need good assessment tools.  The ability to growing cracks as small as 0.01 in. is clearly of great use to bridge owners worldwide – both in terms of improving safety and reducing costs."
