Products of Tomorrow: November 2014

The technologies NASA develops don’t just blast off into space. They also improve our lives here on Earth. Life-saving search-and-rescue tools, implantable medical devices, advances in commercial aircraft safety, increased accuracy in weather forecasting, and the miniature cameras in our cellphones are just...

Tech Needs
Extended-Wear Patches for Skin Hydration

Moisturizers and active ingredients must be held against human skin in a patch format. To enhance uptake, a new material needs to be designed for extended wear from 1-10 hours. Comfort and physical flexibility are two chief requirements. Ideally, the patch will also reduce the appearance of wrinkles....

Tech Needs
Monitoring Battery Health in Solar-Charged Systems

In solar-powered, battery-run systems, each unit’s battery stores electricity generated by the solar panel during the day and provides electricity to a load when required. The systems currently are networked, but no method is in place to determine or report battery health. A client seeks ways...

DBD Device Offers Transdermal Medicine Delivery

DBD Innovations

Iontophoresis is a well-researched technique for delivering medicines and cosmetic agents through the skin. Current techniques, however, are inefficient, and existing devices are often expensive, bulky, and awkward. A Dielectric Barrier Discharge Iontophoresis (DBDI)...

Dispensing Closure Technology Seals and Separates Ingredients

StarOne Group

The Drop-Top™, a container closure and delivery system, features an internal, multi-cavity design that stores up to three separate doses of ingredients, including liquids, powders, gases, granules, or tablets. The dispensing closure technology increases the...

Tech Needs
Sterility Verification of a Flowing Liquid

A client seeks a device capable of detecting contamination in a liquid flow. The system needs to detect non-liquid particles, bacteria, yeasts, mold, and/or spores in a continuous liquid stream. Any proposed sensing methodology must not physically interact with the liquid flowing in the interior of the...

Tech Needs
Fabrics with an Inherent Thickness

A foam shape must be replaced with a knitted, woven, or nonwoven fabric that derives its thickness from the geometric structure of its components. The current application uses polyurethane foams that range from millimeters to 2 cm thick. The foams offer little or no ventilation in a situation where air...

Tech Needs
Additives to Minimize Dirt Accumulation

Polymeric and non-polymeric additives must release dirt from stucco, decks, and other coated architectural surfaces. A client seeks hydrophobic surfaces that are hard rather than tacky, and offer low surface tension and high contact angle. Preferably, a homeowner could spray these enhanced coatings with...
