Vanderbilt University researchers have developed a novel approach for creating dynamic, tunable reflective color displays using an electrochemical modulator. The technology can be implemented into devices requiring low power reflective color displays, such as smart watches and e-readers, and is adaptable for spectral control across a broad spectrum of frequencies from the visible to the far infrared. This technology provides a low power, tunable approach for modulating the optical properties of a material.

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.

Vanderbilt researchers have developed a novel combinatorial logic circuit that prevents the propagation of signal glitches such as those caused by radiation-induced transients. The interlocked-feedback circuit accomplishes this without the loss of any speed. The circuit is designed for robustness in both combinatorial and sequential logic applications.

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.
