Vanderbilt researchers have developed a novel energy-harvesting device capable of efficient electrochemical strain energy harvesting at frequencies as low as 0.01 Hz. The device enables the harvesting of energy produced from low frequencies associated with human motion such as walking and sitting.

Vanderbilt engineers have developed a robotic system for performing sinus and neurosurgery through the nose. This provides a less invasive way to access surgical sites in the sinuses and near the middle of the patient's head, leading to faster recovery times. The robot is modular and sterilizable with detachable cartridge-based instruments. Each instrument is a concentric tube robot, which is a needle-sized tool that can bend and elongate. The system delivers four of these instruments through a single nostril.

Vanderbilt researchers have developed a novel technology for trapping and dynamically manipulating nanoscale objects. Control over miniature objects like proteins can aid in applications such as biological sensing, single molecule analysis, and size-based sorting of nanoscale objects.

Vanderbilt researchers have developed a thermoresponsive filament material for use in 3D printing that can be readily dissolved via cooling. This material has use in a multitude of different applications. One potential application is lost-wax casting for tissue engineering. The present material enables the user to print an intricate vascular structure, embed the structure in an engineered tissue construct, and then dissolve the printed structure to create a hollow vascular network embedded within the tissue construct.
