Soft Tissue Anchor  | Pes planus, or flatfoot, affects approximately 20-30% of the population, with over 3 million cases annually. Currently, corrective procedures focus on rehabilitating the damaged posterior tibial tendon by targeting the flexor digitalis longus (FDL) tendon. This transfer procedure utilizes soft tissue anchor sutures to secure the FDL to the navicular bone. However, these techniques often lead to complications such as anchor pullout and inaccurate suturing. Our goal is to develop a plate-like device that securely fixates the FDL to the navicular bone and other anatomical locations while preserving tissue integrity, thus offering a more reliable and effective surgical approach.

Lunar Stake Prototype  | The project consists of two self-assembling prototype Lunar Stakes. Each stake must be capable of being handled by an autonomous rover and able to read and report back results on its own. This means it must be lightweight, durable, self-extended, and be inserted deeply enough into regolith (moon dust and rock). This is so accelerometers can read back seismic measurements and report back its findings. Through further understanding of regolith and its capabilities, this technology will hopefully pave the way for construction projects on the moon for future space missions.

Hydraulic Bolt Tensioner and Preload Readout | When tightening factory standard bolts, some larger-scale bolts require large amounts of force to torque them. By implementing a hydraulic bolt tensioner, companies can feasibly tighten bolts more efficiently, safely, and uniformly. This is because hydraulic bolt tensioners achieve torquing by connecting to a bolt where hydraulic oil is then added to supply pressure, thus applying a preload force that elongates the bolt to be tightened. To further increase the accuracy of the tensioner and longevity of the bolt, the design implements a preload readout system to inform the user how much torque is generated, ensuring them that no undesirable slippage or deformations will occur.

Miniature Spring Fatigue Tester | This project addresses manufacturing defects in small wire-diameter springs utilized in Sandia National Laboratories mechanisms, prone to fatigue-related failures. Current fatigue testing methods fail to replicate real-world excitation, potentially leading to inaccurate results. Our solution involves developing a fatigue tester capable of mimicking actual use-case conditions while also capable of capturing magnified images of the springs. Integrated with a user-friendly control system and a data acquisition system for pre- and post-testing analysis, the tester ensures product quality assessment alongside fatigue testing, reducing analysis time. Deliverables include a compact, lightweight tester with precise energize and de-energize times, capable of capturing and contrasting time/displacement curves and visual data to evaluate spring performance effectively.
