3D-Printed Ophthalmic Retrobulbar Anesthesia Simulator: Mimicking Anatomical Structures and Providing Tactile Sensations
Objective: A simulator for retrobulbar anesthesia administration mimicking the orbital anatomy and providing tactile sensation is proposed. Methods: The production process involves 3D modeling of anatomical structures on the basis of computerized tomography (CT) images, printing the models using a... Read more

An Instrumented Cochlea Model for the Evaluation of Cochlear Implant Electrical Stimulus Spread
A 3D-printed physical cochlea model with integrated sensing wires is presented, to evaluate the stimulation current spread of a cochlear implant (CI) in a cochlea. These wires are independent from the stimulating electrodes of a CI. Therefore, the measured current spread signals are not influenced by electrode-electrolyte interface potential near the CI, which is an important issue for conventional measurements that causes missing information in current spread distribution in a cochlea. This physical cochlea model provides an objective platform for comparing different CIs, as well as different stimulation modes and configurations, thus potentially offering optimized setup for specific CI patients...

Encapsulation Approaches for In-Stent Wireless Magnetoelastic Sensors
Prior work has shown that wireless magnetoelastic sensors can signal impending stent occlusion, thereby potentially avoiding the most lethal risks of the occlusion. Encapsulation of these sensors within the small inner lumen of the stent remains a critical challenge. The... Read more

Design and Fabrication of a Six Degree-of-Freedom Open Source Hand
Currently, most externally powered prostheses are controlled using electromyography (or EMG), which is the measure of the electrical signals that are produced when voluntary muscle is contracted. One of the major problems is that there are a limited number of... Read more

3D-Printed Airway Splint Saves Life of Infant Born with Severe Tracheobronchomalacia
Half a millennium after Johannes Gutenberg printed the bible, researchers printed a 3D splint that saved the life of an infant born with severe tracheobronchomalacia, a birth defect that causes the airway to collapse. While similar surgeries have been preformed using... Read more
