Richard Sack’s primary research interest is the use of acoustic fields to influence electrospinning and nanofiber formation. His work explores how ultrasonic phased arrays, acoustic holograms, and controlled interference patterns can be used to guide electrospun polymer streams during flight, improving control over deposition, structure, and material formation.

A major focus of this work is acoustic hologram-guided electrospinning, where ultrasonic transducer arrays are used to create pressure-field patterns that affect the path of electrospun fibers before they reach the collector. This approach is intended to address one of the central limitations of conventional electrospinning: the difficulty of controlling where fibers travel, how they deposit, and how structured the resulting nanofiber material becomes.

His research also includes conductive nanofiber production and structured nanofiber materials. This includes development of systems for producing conductive electrospun fibers, as well as concepts for twisting, braiding, or intertwining nanofibers during formation to improve material properties and enable new applications in aerospace, biomedical devices, filtration, sensors, electromagnetic materials, and advanced manufacturing.

Additional areas of research interest include:

• Advanced manufacturing methods that connect digital fabrication, automation,, and applied materials research.
• Biomedical engineering design, assistive technology, rehabilitation-focused devices, and accessibility-oriented engineering projects.
• Research prototyping and experimental system development, including custom fixtures, test platforms, instrumentation, motion systems, microcontroller-based controls, and automated data collection.
• Applied electronics, embedded systems, sensors, instrumentation, industrial controls, robotics, and automation for research and manufacturing applications.
• Laboratory-scale translation of early-stage concepts into testable prototypes, proof-of-concept systems, and commercialization-ready demonstrations.
• Student-centered applied research, including interdisciplinary projects that integrate engineering design, fabrication, testing, documentation, and real-world constraints.
• Technology transfer and commercialization support for university-developed engineering systems, prototypes, and applied research outcomes.

• Hands-on engineering education and applied learning across a broad range of topics
• Student mentoring through design, fabrication, testing, and troubleshooting
• Laboratory safety, equipment use, and technical training
• DFMA and prototype development
• Electronics, instrumentation, microcontrollers, and automation fundamentals

Systems and Methods for Nanofiber Guidance
Intellectual property related to ultrasonic/acoustic guidance of electrospun nanofibers using an array of transducers and a control system to generate dynamic interference patterns that guide polymer nano-streams during electrospinning. The technology is intended to improve control over nanofiber deposition, enable formation of more structured nanofiber materials, and enable continuous post-processing.

System and Method for Intertwining Nanofibers
Intellectual property related to forming intertwined, twisted, or braided nanofiber structures during electrospinning. The system uses movable emitters, conductive support surfaces, raceway-style emitter guidance, magnetic actuation, and controlled emitter motion patterns to intertwine multiple nanofibers before collection.
