Project Summary The 21st Hilton Head Workshop (HH2024) on Solid-State Sensors, Actuators, and Microsystems is slated for June 2 - 6, 2024, at Sonesta Resort, Hilton Head Island, SC, commemorating its 40th anniversary. This biennial event since 1984 celebrates Micro-Electro-Mechanical Systems (MEMS) achievements, envisions future challenges, and aims to address global and national grand challenges in the next 40 years. HH2024, a premier MEMS and Microsystems conference, expects 350-500 participants from diverse academic, industry, and government backgrounds. Past workshops facilitated interactive discussions on microfabrication technologies, presenting recent advancements for sensing, actuation devices, and microsystems across physical, chemical, and biomedical applications. Emerging from a global pandemic, HH2022 focused on "Preparation and Prevention: Tackling our Grand Challenges," exploring heterogeneous microsystems' potential impact on global healthcare and inspiring collaborations. Highlighting nano- and microtechnologies for biomedical imaging, diagnostics, drug delivery, implants, and regenerative medicine, HH2024 encourages interdisciplinary collaboration among various disciplines, including engineering, physics, chemistry, biology, and medicine. Leveraging support from the NIH, the workshop intends to support underrepresented groups in science and engineering through travel awards. Overall, HH2024 reflects NIH's mission by advancing technology, exploring biomedical applications, fostering collaboration, and facilitating research translation for improved human health.
