MIT Engineers Design Framework for Controlling Ultrasound Waves in Microscopic Materials
New research paves the way for advanced materials with ultrasonic wave control capabilities.
Cambridge, MA – Imagine materials so advanced they can control the flow of sound waves at the microscopic level. this futuristic concept is edging closer to reality thanks to a groundbreaking design framework developed by engineers at MIT.
“The multifunctionality of metamaterials — being simultaneously lightweight and strong while having tunable acoustic properties — make them great candidates for use in extreme-condition engineering applications,” explains Carlos Portela, the Robert N.noyce Career Development Chair and assistant professor of mechanical engineering at MIT. “But challenges in miniaturizing and characterizing acoustic metamaterials at high frequencies have hindered progress towards realizing advanced materials that have ultrasonic-wave control capabilities.”
Portela, along with his team from MIT’s Department of Mechanical Engineering and the U.S. Department of Energy’s Kansas City national Security Campus, has overcome these hurdles. Their findings, published in the prestigious journal Science Advances, detail a novel approach to controlling ultrasound waves in microscale acoustic metamaterials.
“Our work proposes a design framework based on precisely positioning microscale spheres to tune how ultrasound waves travel through 3D microscale metamaterials,” says Portela. “Specifically, we investigate how placing microscopic spherical masses within a metamaterial lattice affects how fast ultrasound waves travel throughout, ultimately leading to wave guiding or focusing responses.”
Through innovative, non-destructive laser-ultrasonics characterization, the team experimentally demonstrated the ability to tune elastic-wave velocities within these microscale materials. This breakthrough opens doors to a wide range of applications, including the development of acoustic demultiplexers – devices capable of separating complex acoustic signals.
This research marks a important step forward in the field of metamaterial technology, bringing us closer to a future where materials can be engineered to manipulate sound waves with unprecedented precision.

Cambridge,MA – Scientists at MIT have developed a groundbreaking method for creating microscale acoustic metamaterials,paving the way for revolutionary advancements in ultrasound technology and beyond.
This innovative approach, detailed in a recent study published in Science Advances, utilizes simple geometric changes to manipulate the properties of these tiny structures, allowing for precise control over how sound waves travel through them.
“Using simple geometrical changes, this design framework expands the tunable dynamic property space of metamaterials, enabling straightforward design and fabrication of microscale acoustic metamaterials and devices,” says Carlos M. Portela, a lead researcher on the project.
The team, led by Portela and graduate student Rachel sun, achieved this breakthrough by strategically placing spherical masses onto a spring-like lattice scaffold. This ingenious design allows for the direct manipulation of mass and stiffness, effectively tuning the speed and behavior of sound waves passing through the material.
“The beauty of this framework is that it fundamentally links physical material properties to geometric features,” explains Sun. “By placing spherical masses on a spring-like lattice scaffold, we could create direct analogies for how mass affects quasi-static stiffness and dynamic wave velocity.”
This revelation opens up a world of possibilities for applications in medical ultrasound imaging, information transmission via ultrasound, and even mechanical computing. The ability to precisely control sound waves at such a small scale could lead to the development of highly sensitive ultrasound probes, miniaturized acoustic sensors, and novel devices for manipulating sound energy.
Perhaps most excitingly, the framework’s simplicity and versatility make it adaptable to various fabrication techniques and materials. This means the potential applications extend far beyond the microscale, promising a future where acoustic metamaterials play a crucial role in a wide range of technological advancements.
Controlling Sound at the Smallest Scale: An Interview with Dr. Carlos Portela
(NewsDirectory3) - A team of MIT researchers, led by Dr. Carlos Portela, has recently achieved a remarkable feat: controlling ultrasound waves at the microscale. This breakthrough could revolutionize numerous fields,from medical imaging to mechanical computing. We sat down with Dr.Portela to discuss the implications of this exciting discovery.
NewsDirectory3: Dr. Portela,congratulations on this incredible achievement. Could you explain in layman’s terms what your team has accomplished?
Dr. Portela: Essentially, we’ve found a way to design materials that can precisely control how ultrasound waves travel through them. Imagine it like building with tiny Lego blocks, but instead of making a structure, you’re orchestrating the flow of sound.We do this by strategically arranging microscopic spheres within a lattice structure. This “braced-cubic” design allows us to fine-tune the properties of the material and manipulate the behavior of sound waves.
NewsDirectory3: What are some of the potential applications for this technology?
Dr. Portela: The possibilities are vast! In medicine, we could develop ultrasound imaging systems with much higher resolution, leading to earlier and more accurate diagnoses. Imagine being able to see tumors or internal injuries with pinpoint clarity.
We could also explore targeted drug delivery and non-invasive tissue repair using ultrasound waves focused through these materials.Additionally, controlling sound waves at this scale opens up exciting possibilities for mechanical computing, where calculations are performed using sound instead of electricity. This could lead to smaller, faster, and more efficient computers.
NewsDirectory3: You mentioned acoustic metamaterials. What are they, and why are they critically important for this research?
Dr. Portela: Acoustic metamaterials are engineered materials with unique acoustic properties not found in nature. Think of them as “designer” materials that can manipulate sound in ways we couldn’t even imagine before. miniaturizing these materials while maintaining their ability to control sound at high frequencies was a significant challenge, but our team found a way to overcome it.
NewsDirectory3: What are the next steps for your research?
Dr. Portela: We’re excited to continue exploring the potential applications of this technology. We plan to refine our design framework and create even more complex acoustic metamaterials. ultimately, we hope to see these materials implemented in real-world devices that benefit society.
