Smart Exoskeleton Hand With Soft Electronics, Andrew Choi, Han Ha, Gabrielle Jones, Gregory Zobel

Capstone Design Expo Posters

Many people in the modern world suffer from a loss of hand and finger strength due to diseases in the muscle or nervous system such as ALS, Muscular Atrophy, and more. This problem has become more widespread with the surge of technology over the last 5-10 years. Therefore, we have created a smart exoskeleton hand with soft electronics that will allow people with less than average hand strength to perform daily activities.

The exoskeleton device utilizes small, lightweight linear actuators to provide additional strength to the user’s fingers and the hand itself will be 3D-printed with ABS and PLA plastics …

3d Heart Model For Mapping Rf Ablation Sites, Danielle Corsino, Ashleigh Mims, Andrew Potter, Alejandro Rivera

Electro-Cardiologists routinely insert radiofrequency probes into the heart and conduct targeted ablation procedures to correct irregular heartbeats. Current techniques are very experience and “touch” based, and require the novice cardiologist about 50 procedures to become proficient. There is a need for a functional heart model device that can be used to reduce the amount of procedures on human patients before cardiologist become proficient. Project constraints included limited software availability for segmenting accuracy, available 3D printing technology and materials, and cost to 3D print heart models due to the complex geometry. The team began with a CT scan, ITK SNAP and …

3d Printed Teeth: Anatomically Correct Primary Replicas, Anh Nguyen, Stefan Harris

Capstone Design Expo Posters

The current method of molding teeth, especially primary teeth, cannot accurately reproduce internal tooth structures. Therefore, there is a need for primary teeth to be made anatomically accurate on-demand with the ability to customize a model for specific patients. This project aims that any tooth extracted digitally from a Dental Cone Beam computed tomography (CBCT) scan of a child's mouth can be 3D printed into an accurate replicate with which dental students can practice. Constraints include viable materials that can be printed by a 3D printer, represent tooth anatomy and provide desirable mechanical properties compatible with the dental drilling operation. …
