Sensors for Future NASA Missions To Be Manufactured With Additive Technology

The aerospace sector stands out as a prime beneficiary of additive manufacturing‘s advantages. Through 3D printing, intricate, lightweight components can now be designed and produced with unprecedented speed and efficiency, revolutionizing not only aerospace but various other industries as well. A groundbreaking moment in space exploration and additive manufacturing occurred when a team from the FAMU-FSU College of Engineering, a collaborative institution between Florida A&M University and Florida State University, successfully developed 3D printed sensors for NASA. This achievement represents a notable stride in leveraging 3D printing technology to craft high-performance components, promising remarkable advancements in both space exploration and manufacturing capabilities.

The research team, consisting of engineering students and experienced engineers, was led by Professor Subramanian Ramakrishnan of the Department of Chemical and Biomedical Engineering. With the expertise of the multidisciplinary team and the decision to use innovative technologies such as additive technologies, they were able to produce state-of-the-art sensors that mechanically outperform conventional sensors used in the aerospace industry. This breakthrough is the result of the NASA-driven project Additive Manufacturing of Electronics for NASA Applications, on which work will continue for another year. The universities received $300,000 for research and development of the sensors, which will be supported by NASA engineers.

Sensors play a pivotal role in aerospace endeavors, translating physical phenomena into electrical signals for computer processing. This critical function enables engineers to comprehend the behavior of spacecraft systems amid the rigors of space. Among the array of sensor types with specific functions, strain gauges stand out. These sensors are instrumental in measuring the deformation of objects, offering invaluable insights into structural integrity. During aerospace missions, these devices assume a paramount role, diligently monitoring systems in real-time. Their vigilance is essential in averting any deformations that might jeopardize spacecraft safety and operational efficiency.
