The Langevin piezoelectric transducer is an “electrical-mechanical energy converter” that converts electrical signals into mechanical displacements. This transducer is usually used in many applications requiring vibration. Unictron’s Langevin piezoelectric transducer is a kind of piezoelectric transducer that can generate the specified force and vibration displacement. Unictron can adjust the Langevin transducer’s assembly type (two-piece or multi-piece piezoelectric assembly) according to client requirements. Unictron’s Langevin piezoelectric transducers provide stable and consistent output, displacement,  mechanical properties, as well as excellent reliability and durability.

Unictron Technologies Corporation is one of the leading suppliers of piezoelectric ceramic components in Taiwan. Our engineering team has over 25 years of experience in piezoelectric ceramics research and has proprietary material formulations and ceramic processing technologies.
