I established Piezoelectric Technology in 2000. We have developed the various actuators and applied modules based on technical know-how for 11 years. We are the only company among a few piezo motor manufacturers in the world. We’ve been developing various actuators such as rotary ultrasonic motor, cutter and butterfly actuator since TULA was released in 2004. Compared with electric motor (DC/AC motor), the advantages of TULA are no noise, high resolution, low power consumption. Our motor is generally applied to AF(Auto Focus)/OIS(Optical Image Stabilizer)/ICR(Infrared Cut Removal) module for barcode reader, camera, CCTV, automation equipment, semiconductor device, etc. We have many big customers related with relevant field such as Samsung, Intermec, Securion24, Technohands, etc.

I joined korea institute of science and technology institute(KIST) as researcher.I took participate in the project to develop TULA(Tiny Ultrasonic Linear Actuator) at that time.TULA is the product to use piezoelectric effect, which means making linear motion using vibration by compression and expansion of piezoelectric transducer.

I joined HALLA group and started working Mando Corporation in 1992.I gained various experiences in many fields for 9 years such as sales, calculation and analysis of product cost ,production/delivery/collection/business connection, development management, business analysis, etc.
