Channel Technologies Group

We design and manufacture piezoelectric materials, transducers, turnkey integrated systems and optical solution technologies that support mission critical applications for military and essential commercial market platforms. Based in Santa Barbara, Calif. and with a second manufacturing site in Bolingbrook, Ill., Channel Technologies Group (CTG) first began manufacturing piezoelectric ceramics in 1959. Since that time, CTG has grown and developed unparalleled in-house expertise, allowing CTG to expand its product offerings to include piezoelectric ceramics, piezoelectric single crystals, transducers, turnkey sonar systems and electro-optical calibration and testing equipment. Our products are used in a multitude of applications, and by a wide variety of end-users including medical device manufacturers, marine explorers and energy companies. We also service customers in the defense industry, including several departments of the U.S. Navy and many leading defense contractors.
