Hundreds of researchers gathered in Hilton Head, SC, from June 5-9, for the 2022 Hilton Head Solid-State Sensors, Actuators, and Microsystems Workshop. This was the 20th meeting of the biennial event, which is known as one of the premier workshops for researchers to discuss recent advances in microelectromechanical systems (MEMS).

The workshop started in 1984 and draws attendees from academia, industry, and government organizations with diverse backgrounds in engineering and science. It opened to international attendees in 2020 and provides a forum for knowledge exchange and collaboration. This year’s theme was "Preparation and Prevention: Tackling our Grand Challenges."

Nine papers from Georgia Tech researchers in the Institute for Electronics and Nanotechnology (IEN) were accepted to the conference. The paper, A Microtip Equipped Bidirectional Microrobot for Navigating on and Penetrating a Leaf Surface, presented by Tony H. Wang, Dea Gyu Kim, Zhijian Hao, and Azadeh Ansari, won the Springer Nature Best Poster Award. In addition, the paper Wafer-Level High-Aspect-Ratio Deep Reactive Ion Etching of 4h-Silicon Carbide on Insulator Substrates presented by Ardalan Lotfi, Micheal P. Hardin, Zhenming Liu, Alex Wood, Chris Bolton, Kevin Riddell, Huma Ashraf, Joanne Carpenter, and Farrokh Ayazi, was one of two runners up in the category.

“I consider this the flagship North American conference for MEMS researchers,” said IEN Executive Director Oliver Brand. “It is a highly interactive workshop and a great opportunity for our graduate students to learn about the newest research and mingle with their peers from the top MEMS research groups across the country.”

In addition to Georgia Tech’s strong presence in paper presentations, IEN Principal Research Scientist Paul Joseph ran a National Nanotechnology Coordinated Infrastructure (NNCI) booth to spread the word about the initiative, which the National Science Foundation funds. Ansari, Brand, Ayazi, and Nima Ghalichechian also served on the local organizing committee, and IEN sponsored the workshop.
