Seals are used to facilitate the joining of two items, usually temporarily. At some point in the future, it is expected that the items will need to be separated. This innovation enables control of the adhesive properties of silicone-based elastomers. The innovation may also be effective on...

Aero-assist technologies are used to control the velocity of exploration vehicles (EVs) when entering Earth or other planetary atmospheres. Since entry of EVs in planetary atmospheres results in significant heating, thermally stable aero-assist technologies are required to...

MIT engineers have created a new polymer film that can generate electricity by drawing on a ubiquitous source: water vapor. The new material changes its shape after absorbing tiny amounts of evaporated water, allowing it to repeatedly curl up and down. Harnessing this continuous motion could drive...

Adding phase change material (PCM) to a mission payload can maintain its temperature above the cold survival limit, without power, for several hours in space. For the International Space Station, PCM is melted by heaters just prior to the payload...

A climbing robot needs to use its adhesive patches over and over again as it scales a slope. Replacing the adhesive at each step is generally impractical. If the adhesive or attachment mechanism cannot be used repeatedly, then the robot must carry an extra load of this adhesive to apply a fresh layer with each...

Prior approaches to transformer-like robots had only very limited success. They suffer from lack of reliability, ability to integrate large surfaces, and very modest change in overall shape. Robots can now be built from two-dimensional (2D) layers of robotic fabric. This expands...

The Air Force Research Laboratory (AFRL) has developed and demonstrated a new process by tape-wrapping large, unique-shaped carbon-carbon aircraft shells, or aeroshells. Aeroshells are formed into a lifting body shape called Hypersonic Glide Vehicles, which are used as the primary...

A new material offers a lighter weight and at least 30% higher usability strength compared to traditional steel. The equipment necessary for the production of the new technology is identical to equipment used for the manufacturing of conventional steel. It does not require other machinery, and...

A new composite material of singlewalled carbon nanotubes (SWNTs) displays radio frequency (0 to 1 GHz) permittivity properties that can be adjusted based upon the nanotube composition. When varying ratios of raw to functionalized SWNTs are blended into the silicone elastomer matrix at a...

An organic polybutadiene (PB) rubber-based aerogel insulation material was developed that will provide superior thermal insulation and inherent radiation protection, exhibiting the flexibility, resiliency, toughness, and durability typical of the parent polymer, yet with the low density and superior insulation properties...

At low operating temperatures, commercially available electrode materials for lithium-ion batteries do not fully meet the energy and power requirements for NASA’s exploration activities. The composite cathode under development is projected to provide the required...

Designs incorporating variations in capillary geometry and hydrophilic and/or antibacterial surface properties have been developed that are capable of passive gas/liquid separation and passive water flow. These designs can incorporate capillary grooves and/or surfaces arranged to create linear...

A new food-grade heat-seal adhesive is needed for roll-coated film lids. New chemistries must be formulated into a waterbased matrix to seal transparent film onto plastic trays containing food or medical materials. The organization deals primarily with polyester films (APET/CPET) and trays, and containers made from polystyrene...

Cabin environmental control is an important issue for a successful Moon mission. Due to the unique environment of the Moon, lunar dust control is one of the main problems that significantly diminishes the air quality inside spacecraft cabins. Therefore, this innovation was motivated by NASA’s need to minimize the negative...

At the U.S. Army Research Laboratory, scientists and engineers have been studying how they can make higher-performance materials for soldiers at lighter weights. The challenge has led to the ARL Enterprise for Multiscale Research of Materials, made up of in-house research and most...

A team of experts in mechanics, materials science, and tissue engineering at Harvard has created an extremely stretchy and tough gel that has potential as a replacement for damaged cartilage in human joints.

A flexible, organic polyurea-based aerogel insulation material was developed that will provide superior thermal insulation and inherent radiation protection for government and commercial applications. The rubbery polyurea-based aerogel exhibits little dustiness, good flexibility and toughness, and...

Scientists at MIT and the University of Pennsylvania are taking more than inspiration from nature — they’re taking ingredients. The group has genetically engineered muscle cells to flex in response to light, and is using the light-sensitive tissue to build highly articulated robots. This...
