Adaptive Membranes for Comfortable Protective Wear

This dual-membrane technology provides apparel with a high degree of comfort, passing air and water vapor easily. The garment (or survival enclosure) can instantly be made impervious with the flip of a switch on the belt-mounted power pack. The garment can be toggled between high comfort and high protection modes quickly and repeatedly, depending on the environmental conditions. A voltage is required to maintain one of the states. These garments are ideal for situations where the environment is usually normal but can rapidly change to hazardous, such as first responders, HAZMAT teams, hospital personnel, militia, or chemical plant workers.

Soft-Feel Grain Surface Treatment for Hard Plastic Mimics Sensation on Fingertips

This technology gives hard-surface plastics a soft and moist feel by imposing a “grain” or texturing onto the surface. It has application in automotive interiors, household utensils, electronics, mobile phones, and other locations where a hard plastic surface would benefit from feeling softer. The science is based on the study of the fingerprint. The more surface area of the fingertip that touches a surface, the more the brain interprets that sensation as “soft” and “moist.” The soft-feel grain surface treatment consists of a precise series of tiny bumps and larger bumps designed to increase the area of the surface in contact with the fingertip.

Development of Organic Materials that Melt by Light Irradiation

AIST has developed organic materials that melt from solid to liquid with only the irradiation of light, without heating, and can be restored to their original solid state. Unlike irreversible photosensitive resins, which cannot be restored to their original state after their state has changed once, the developed organic materials undergo state transitions by photoisomerization. These synthesized compounds have a molecular weight of about 1,100-1,700 and undergo photoisomerization even in crystals, so that they change from solid state to liquid state by light.

Flexible Absorbent Binder for Packaging Applications

Kimberly-Clark Corporation Flexible Absorbent Binder (FAB) is a transparent polymer cured from a water-based solution. It is ideal for maintaining in-package humidity during shelf life and transport without drying out the package contents. FAB can make a new product with unique liquid-and vapor-handling capabilities, or it can be incorporated into other products and packaging that need humidity control or dispensing. It acts as a binder and does not require additional binders to hold it in place on a suitable substrate.

LED-Based Lighting is Two Times Brighter Than Other Technology

Code 3Code 3’s TriCore is an LED-based optical lighting technology that is two times brighter than other technology currently on the market, according to the company. It uses only one-third the power of conventional lighting systems, yielding higher watt-for-watt efficiency. The brightness and efficiency is achieved through a design that combines an LED chip with an optical-based lens system. The LED chip (die) system overcomes all limitations imposed by pre-packaged LEDs, and the optical-based lens system removes the inefficiencies within reflective-based lighting technology.

Self-Healing Slide Ring Material Paint

A slide ring material (SRM) paint is able to heal a majority of surface scratches by itself. When disturbed by minor abrasions, the paint’s cross-linked molecules retain mobility, and the oleophilic polyrotaxane coating redistributes its tension to slide back into place along the polymer chains, erasing the blemish.

Electronic Device for Damping Impacts

Springs, polymers, and pneumatic or hydraulic devices react to impacts, but a recently developed damping technology calculates and controls the forces that should be applied. Within the device, two electromagnets with different polarities are put in contact, and the repulsion force is used against the forces generated by contact. A specialized micro-controlled circuit connected to special sensors calculates, in real time, the appropriate level of magnetic field strength, in order to dampen the received impact, whose intensity of force can be contained in a wide variation field.
