Ultrasonic transducer project management in a nutshell
Husain Shekhani • May 23, 2021
Ultrasonic transducer project development is organized into three hierarchical topics:
- Tactics
- Tactics are the exact things engineers do during the project. These are the samples you build, the tests you run, simulations you construct, and operational aspects of a project
- Objectives
- The objective is the description of the goal. For example, we want to have a transducer that operates at XX performance metric with XX% yield and last for XX months of continuous operation, by XX date in the future
- Strategy
- The strategy is the guideline by which you decide on the tactics which will achieve the objective. For example, will you build a transducer from scratch or improve an existing design? Will you perform system testing early or after a transducer has been well defined?
Explicitly listing out your tactics, objectives, and strategy is essential for an unbiased look at your ultrasonic transducer project's potential for success.

I hosted a webinar on January 26, 2024 on " Everything you need to know about designing and assembling power ultrasonic transducers " You can watch the recording on my YouTube Channel here: https://youtu.be/oAMjCGBXYms Here is a link to the pdf of the presentation notes: Webinar 24 - everything power transducers.pdf Summary In this webinar I gave a "catch-all" presentation on bolt-clamped ultrasonic power transducer. Specifically, I discussed: -How to design a power ultrasonic transducer (bolt-clamped) -How to assembly the transducer - How to test the transducer *** Announcement *** My next webinar will be on Friday, February 23, 2023 at 11AM EST. I will cover "How to determine to determine the requirements of your transducer application using an R&D electrical driver” (Topic will change based on LinkedIn poll to come) Here is the link to sign up for the upcoming webinar: https://www.ultrasonicadvisors.com/monthly-ultrasonic-webinar
I hosted a webinar on December 29, 2023 on " What happens to displacement at the antiresonance frequency of an ultrasonic transducer " You can watch the recording on my YouTube Channel here: https://youtu.be/Zj9fXkaEADw Here is a link to the pdf of the whiteboard notes: Webinar 23 antiresonance displacement.pdf Here is a link to the Waveforms workspace file: webinar23_wvforms_displacement.dwf3work Summary Using a laser doppler vibrometer, I demonstrate that the mechanical displacement is not affected by the antiresonance phenomenon of ultrasonic transducers. In this webinar, I show experiments and talk about theory. I also talk about mechanical antiresonance. *** Announcement *** My next webinar will be on Friday, January 5, 2023 at 11AM EST.
