Adaptive High-Temperature End Effector

Additive manufacturing (3D printing) can produce everything from artificial body parts to full-sized houses. The Adaptive High-Temperature End Effector is designed to help reduce production time, enable mass production and lower costs for small-batch production of specialty items. Using a robotic arm equipped with an end effector that functions like tongs, alloy steel grippers and aluminum oxide castable ceramic insulators, this technology also can eliminate risks involved in handling high-temperature metal, supporting new capabilities in additive manufacturing.

To eliminate pest infestations in elevated areas, pest control service personnel often use ladders, lifts or roof climbing equipment and wear cumbersome protective gear and backpack sprayers, increasing the risk of falls. With AeroPest, unmanned aerial vehicles, or flying drones, are used to carry a precision spraying system to eliminate pests in restricted areas and at heights previously unreachable. This system can precisely spray or inject only the necessary insecticide dosage, avoiding chemical overspray and environmentally harmful runoff while reducing injury risks.

Hydrocephalus is the buildup of fluid within the brain’s ventricles. It affects patients of all ages, including one in 500 children worldwide, and is typically treated with a ventriculoperitoneal shunt. However, shunt malfunctions are frequent, extremely difficult to detect and life-threatening if not treated promptly. The CatheSure is the first device that noninvasively and wirelessly detects ventriculoperitoneal shunt failure. Rapid, cost effective and easy to use, it is integrated with an existing shunt and lasts the entire lifetime of the shunt, without requiring battery replacements or Wi-Fi access.

Dynamic Brace

Clubfoot, a birth defect causing the foot or feet to turn inward and downward, affects one in 1,000 U.S. infants annually and can hinder the ability to walk. With a typical “boots and bar” brace system, which rigidly connects and demobilizes the feet, one in four children experience relapse, often due to noncompliance. The soft, flexible, lightweight Dynamic Brace increases compliance, eliminating the need for a connecting bar and supporting mobility and comfort by allowing both feet to move independently.

Over the next 25 years, global food demand is expected to increase by 70%, leading to more water usage. Traditional above-ground irrigation methods are inefficient and often involve evaporation loss, and subsurface irrigation requires a costly initial investment. Sequestron is an infiltration insert method that suppresses evaporation using a topsoil bed, keeping water at the root zone and preventing it from reaching groundwater reserves by the Percolation Control Layer. Delivering many advantages over standard techniques, it can be implemented using materials that are readily available to most farmers.

Agricultural pesticide pollution is responsible for about 200,000 deaths and 385 million acute illnesses annually. Only 2% of sprayed pesticide reaches targeted plant surfaces because these surfaces are water repellant, so pesticides are regularly oversprayed. AgZen-Cloak technology cloaks droplets of pesticide-laden water with an ultra-thin layer of biodegradable, food-safe, plant-derived oil to increase retention on plants. This invention could help farmers use approximately 80% less spray and ensure better crop protection, yield and revenue while reducing pollution.

Sepsis, which occurs when the body’s response to infection damages its own organs, results in death for about 20% of infected patients. Treatment success often depends on the speed of diagnosis, so A-SEP focuses on quickly detecting endotoxin concentration in blood plasma. Building on a limulus amebocyte lysate (LAL) inversion test, A-SEP uses a paper-based microfluidic test kit to determine the level of infection in patients’ blood. This low-cost technology can be deployed around the world to combat the disproportionate deaths in low-resource settings.

Allergies are the sixth leading cause of chronic disease in the U.S. and can be life-threatening. Currently, the best allergy testing method is a skin prick test conducted by an allergist. However, there is just one allergist per 50,000 people in the U.S. Using a new optical sensing technology to measure mast cell degranulation, epiSLS is the first point-of-care allergy test. Offering accuracy, speed and accessibility, epiSLS can help provide the highest quality care regardless of access to specialists.

Hypoxia Imager for Surgery Guidance

>>View Video

An estimated 1.9 million new cancer diagnoses are expected to occur in the U.S. in 2022. The primary modality for solid tumor cancer treatment is surgery. Unfortunately, tumor tissue can be missed during resection, increasing the risk of cancer recurrence. Surgery can be made more specific using fluorescent markers to enhance contrast during tumor resection. The Hypoxia Imager for Surgery Guidance is a time-gated optical system enabling real-time imaging of hypoxia, or lack of oxygen. As tumors are hypoxic, imaging oxygen distribution can greatly enhance surgery outcome.

Currently, fewer than 9% of drugs entering clinical trials are approved for the marketplace. To effectively predict patient responses to drugs and reduce the time and money needed to bring drugs to market, OCTOPUS enables the growth of stem cell-derived mini-organs, or organoids, which mimic the structure and function of human organs and can grow to the necessary maturity to correctly predict responses to specific therapeutics. This accessible approach also presents the possibility of generating patient-specific organoids for personalized medicine.
