Modeling of ultrasonic welding of plastics and 3D printing consolidation
28 February at 10 am EST / 3pm GMT
Lokesh Karthik Narayanan, Assistant Professor
Industrial & Manufacturing Engineering, North Dakota State University
As a researcher Dr. Narayanan’s research interests centers on development of scalable 3D biofabrication processes that enable manufacturing of engineered tissues. Through his research, he is addressing the issues that hinder the translation of processes to the industry such as scalability and quality control. His latest research investigates the use of impedance sensing to monitor the biological quality characteristics of engineered tissue. His vision is to model the process function relationships and engineer semi-autonomous cyber-physical systems for tissue and biomedical device manufacturing.
Dr. Narayanan has served as the instructor for core manufacturing and design courses at NC State and teaches CAD/CAM (IME 380) and automation (IME 482) at NDSU. He is a member of the Industrial and Systems Engineers (IISE), Society of Manufacturing Engineers (SME) and is a member of student relations committee in the national chapter of SME.
Participant interaction and questions will be encouraged.
This edition of Virtual Collaborations will be available to UIA members at $50 / students at $25 / nonmembers at $75.

Virtual Collaborations for 2022
This year's virtual collaborations have been very well received and as a result we are turning them into a regular program of the UIA.
Look forward to invites for four separate sessions during the course of the year, in February, June, September and November. We have selected this schedule so that we can bring you great content on a regular basis but not interfere with our annual conference or summer holidays! And we will be adding a new wrinkle to these presentations, a mini-symposium! The presentations in February, June and November will continue with our 1 hour format and a topic of discussion, but our September session will be an expanded 2 hour mini symposium with a series of presentations on a specific area of ultrasonic technology, ranging from ceramics, transducers, control systems waveguides and other technologies. And don’t forget our main symposium in April!
We look forward to seeing you at these presentations during the course of the year!

Fundamentals of Langevin Transducer Design – A Tribute to George Bromfield Featuring Tony Crandall and Jeff Vaitekunas
Among George Bromfield’s many other accomplishments and contributions, he was a master of design of ultrasonic transducers. This collaboration will focus on the design fundamentals of Langevin-type transducers, and the use of PiezoTran modeling software to quickly and accurately iterate to a design. Many “tricks of the trade” that George taught will be discussed, with particular reference to the use of PiezoTran as well as more general knowledge that George has passed on to all of us to continue in his absence.
Ultrasound in Surgical Devices: Advances in Robotic Surgery & HIFU applications
Featuring Kevin Houser, PE,Director, IP Strategy, Engineering Fellow, Intellectual Property Center of Excellence, Johnson & Johnson, Ethicon Endo-Surgery
Regulatory measurement requirements for ultrasonic surgical devices: Relevance of acoustic characteristics to surgical performance
Featuring Mark E. Schafer, PhD FASA FAIUM, Research Professor,
School of Biomedical Engineering, Science and Health Systems, Drexel University
Tools and techniques for characterizing transducers

The first Virtual Collaboration was held on Thursday, 24 September 2020
One of my favorite aspects of Ultrasonic Industry Association symposiums is the collaboration that occurs during breaks in the actual symposium presentations. Ultrasonic technology is highly non-linear and often confounding, and bouncing thoughts with peers is practically impossible on a day to day basis due to the significant intellectual investment necessary to understand the issues. With the current pandemic, it is not feasible for many to meet in person and have these collaborations. That is why I am looking forward to the UIA’s virtual collaboration on applying pre-load to Langevin-type piezoelectric transducers. Over the years I have experienced several instances of pre-load issues that at the time were confusing, but with hindsight are completely understandable. These collaborative discussions provide the insight needed to overcome common issues that are otherwise difficult to comprehend.
