October 22, 2024 - Depew, NY - PCB Piezotronics (PCB®) is proud to announce that our team member, Dr. Jeffrey J. Dosch, will receive the Shock and Vibration Exchange (SAVE) Lifetime Achievement Award at the upcoming Shock and Vibration Symposium in Dallas, TX, November 3-7.
According to SAVE, this award seeks to honor individuals who, through a lifetime of professional dedication, have made outstanding contributions to the field of shock and vibration: "The Lifetime Achievement Award shall be made to a person whose contributions to the field of shock and vibration are of such magnitude that they significantly improved the state of the art or state of practice at the time." Dosch's storied career certainly meets this criteria.
Dosch's entire career has been devoted to advancing the field of vibration measurement through the development of new sensors, development of improved calibration techniques, and numerous publications on sensing technologies and calibration.
As a graduate student at the State University of New York at Buffalo, he developed a method to use a single piezoceramic as both the sensor and actuator in closed loop vibration control. The resulting paper on "self-sensing actuators" became a seminal work in the then newly emerging field of active vibration control.
Since 1993, Dosch has been pushing the boundaries of sensor technologies at PCB. As a young engineer, he developed a number of piezoelectric actuators and sensors for use in active vibration control. PCB Model 740 strain sensor developed at that time is still widely used today for measurement of dynamic strain.
As leader of the Research and Development group at PCB, he advanced the field of measurement and calibration, specifically in the areas of pyroshock, high temperature vibration, and accelerometer calibration.
Before the development of PCB's 350 series shock piezoceramic sensors it was believed piezoceramic could not be used for pyroshock and that the problems of zero-shift were inherent in the piezoceramic technology. Today the PCB 350 series piezoceramic shock sensor is the measurement standard for many pyroshock applications providing low cost, robustness, and measurement fidelity that could not be achieved with other technologies.
The PCB R&D group was also responsible for the development of high temperature sensors incorporating newly developed "quartz homolog" crystals. These new sensors had higher temperature ratings, greater robustness, and better measurement accuracy.
In the area of accelerometer calibration, under Dosch's R&D leadership, PCB developed its own primary laser calibration facility greatly advancing the precision of vibration calibration. An important part of this work was the development of a better calibration shaker with high resonance, low transverse motion, and stable internal reference. This shaker, now sold through The Modal Shop, is standard for hundreds of calibration laboratories throughout the world. Other calibration advancements include Hopkinson bar for calibration of shock sensors to 100,000g and system for automated testing accelerometer transverse motion.
Dosch's career has been dedicated to pushing vibration measurement boundaries. From pioneering self-sensing actuators as a PhD student to developing piezoelectric technology at PCB, he's left an indelible mark. His leadership in R&D led to breakthroughs in shock and accelerometer calibration, redefining standards and driving the field forward. His innovations are used in calibration labs worldwide, cementing his legacy as a visionary in vibration technology.
PCB is proud to have Dosch as a member of our team and thankful to SAVE for honoring him with a Lifetime Achievement Award.
