Welcome to Piezo-Metrics

Herb has always had the curiosity and passion that characterizes great scientists and engineers. After serving in the U.S. Army in the Missile Command, Herb set out to be a world-class rocket scientist and pursued higher education. He has degrees in Chemistry, Physics, and Aeronautical Engineering (with an Electronics minor) and did extensive coursework in mathematics, computer programming, and semiconductor electronics.

Herb’s professional career started as an Aeronautical Engineer for the U.S. Navy, and then an Instrumentation Engineer at Rocketdyne. While at Rocketdyne, Herb became a sensor expert and discovered the benefits of semiconductor strain gages.

After serving as Chief Engineer at Dynasciences Corp and Vice President at Valid Data, Herb co-founded Senso-Metrics, and began a successful career as an entrepreneur and sensor designer. It was during his tenure at Senso-Metrics, that Herb’s vision of a semiconductor strain gage manufacturing business led him to acquire the assets of Micron Instruments in 1980 and incorporate as Piezo-Metrics, Inc. dba Micron Instruments.

Today, Piezo-Metrics is the world’s leading supplier of semiconductor strain gages and sensor gaging services, with over 100 customers in over 40 countries.

Herb is best known for his keen insight in sensor design and passion for guiding Piezo-Metrics’ product division and its customers in creating world-class sensors. It was Herb that designed the worldwide standard sensor for monitoring solid rocket motor aging, recognized by NATO as a key component in improving safety and reducing lifecycle costs of expensive and mission-critical assets. And it was Herb who played a key role in the design of one of NASA’s Mars 2020 Perseverance robot sensors, now roaming the red Planet.

Herb passed away in March 2022. His Legacy will live on, as Piezo-Metrics continues to drive innovation and technical leadership and a strong commitment to customer satisfaction.

Dr. Robert Mueller possesses over 40 years of experience in technical team management, engineering development, and consulting, including high-speed parallel computers, computer operating systems, sensors, and wireless sensing communication systems. During his career he has developed advanced wireless tracking systems for the U.S. Navy Supply Command (Aviation Repair Parts), U.S. Navy Munitions Information Systems (tracking Navy, Marine Corp, and Coast Guard munitions, worldwide), and the U.S. Marine Corp Aviation Logistics Squadron (Expeditionary Pack-up Kits for forward deployment). He has also designed and installed the first zero-SSD wireless sensing system to be deployed in live missile containers in the central U.S. Air Forces in Europe (USAFE) munitions storage area, as well as served as an International Consultant and Wireless Sensing Subject Matter Expert for Raytheon Missile Systems.

Dr. Mueller was the technical lead on the development and test of the wireless sensing system for U.S. Air Force Research Laboratory (AFRL) Integrated Motor Life Management, Data Acquisition and Analysis program (IMLM DAAS) and a technical team member on the AFRL Motor Aging and Surveillance project. He has been a U.S. appointed Technical Member of the NATO Power & Propulsion Panel, Applied Vehicle Technology, Science & Technology organization since 2007 and has received the 2016 NATO Scientific Achievement Award for co-chairing a Munitions Health Management technology demonstration at the NATO Headquarters, Brussels.

Dr. Mueller was tenured Associate Professor of Computer Science at Colorado State University and currently serves as the CEO and Chairman of the Board of Directors at Piezo-Metrics, Inc.

Dr. Franklin Wong was employed for over thirty years by the Canadian Department of National Defense as a Defense Scientist. During that time, he established himself nationally and internationally as an expert in solid rocket motor health monitoring.

Dr. Wong’s expertise covers the use of material models in finite element analyses to predict the behavior of structures under complex loading conditions and the instrumentation of structures in general, and solid rocket motors in particular. He is skilled in the laboratory characterization of a wide variety of materials ranging from polymers to metals. The service life prediction technologies that Dr. Wong developed as a Defense Scientist have been used for life-cycle management of the Canadian fleet of air-to-air, air-to-ground and navy guided and unguided missiles.

As a Principal Scientist at Piezo-Metrics Inc., he applies his knowledge and expertise to the development of innovative, high accuracy and reliable sensors that have wide application to defense, aerospace, medical and industrial sectors. Currently, he’s advancing the state-of-the-art in solid propellant sensors as Principal Investigator for the Air Force Research Laboratory, Motor Aging and Surveillance Technology Program.

Paul Kim has served as Production Manager for Piezo-Metrics for over three decades. During that time Paul’s extensive experience has included a mastery of sensor engineering, electronics, instrumentation, and testing. His impressive resume includes knowledge of Wheatstone bridge temperature compensation principles, Dual Bond Stress and Temperature (DBST) sensor fabrication, wiring and packaging, and sensor pressure and temperature characterization procedures. Additionally, he has balanced and temperature compensated hundreds of DBST sensors and client transducers as well as thousands of the MP line of pressure transducers.

He currently recruits and trains production technicians for the company along with organizing gaging production schedules to meet the company’s sales demands.

With over thirty-five years of experience in the Test & Measurement Industry, Bryan Pierce brings valuable expertise in military, space, oil, and medical applications to the Piezo-Metrics’ team. During his lengthy career at Senso-Metrics his duties included Engineering and Document Control, Quality Control and Inspection Manager, Research and Development of new and existing products, and serving as a Purchasing Manager. He also is a Certified IPC J-STD-001 solder trainer (CIT).

As the Quality and Assurance Manager at Piezo-Metrics, Bryan is continually working towards improving products and services with a focus towards inspection of finished products and processes, implementation of quality procedures to ensure product quality, and analysis and response to customer issues.
