Sterilizable Applicator for Pre-Mixed Liquid Formulation

An organization needs an inexpensive device to deliver a pre-measured amount of liquid evenly to a surface. The applicator is intended for a single use, must be able to be sterilized after final assembly, and needs to hold enough liquid or gel to cover about 1 to 3 square feet of surface completely. The user’s hands cannot touch either the liquid or the surface to which the liquid is being applied. The design should also be scalable so that units delivering as little as 3 mL can be manufactured.

Force-Feedback Mechanism

A torque-feedback mechanism must measure force, pressure, and displacement. The hybrid system or multi-part assembly requires haptic, visual, sound, temperature, or vibration feedback instruments. The technology may take the form of either a standalone sensor cube that flashes according to pressure, or a material that changes behavior, color, or texture. The technology must also be recyclable and sustainable for the environment. No battery is needed; energy harvesting should be possible from vibration, force, and solar power.

Piezo-Powered Actuators Offer Reduction in Weight

A set of piezoelectric actuators weighs 4 to 50 times less than other robotic actuators in end-effectors, including hydraulic or solenoid devices. The small piezos use ultra-low power: 3 mA holding current at 6.8 VDC, 7.5 mW. The piezo technology is a scalable actuator moved by a pre-loaded piezo stack. One- and two-armed versions are available.

Microscopic Sphere Production Process Eliminates Classification Needs After Processing

A new process produces microspheres of an extremely narrow size distribution and high homogeneity, measuring between 2 and 10 μm. The process can make the microscopic spheres from any material that can be polymerized; acrylic and styrene spheres have been produced.

Creation of Novel Optical Effects

A client seeks transformative technologies that will enable a variety of optical effects or hidden messaging to be created directly onto consumer products and its packaging. Reversible effects that are triggered by external stimuli, such as water (hydrochromic) and light (photochromic), are of interest. Solutions may include novel inks, transformative (phase change) materials, innovative labeling systems, liquid crystals, or holographic imaging. The product must be nontoxic, and should ideally enable multiple colors and effects.

Reduction of Plastics Used in Packaging

An organization must reduce the amount of plastic resin used in packaging, while maintaining the package’s structural integrity and functionality through the supply chain. It may be possible, for example, to inject air bubbles into plastic resin in such a way as to maintain container size, shape, and strength. Mold-in structural members may also be used to decrease weight and material use, while preserving packaging functionality. The client seeks compatibility with blow-molding technologies, but is open to injection-molding options if they result in a solution that provides lower cost and/or resin content.

New Shipping Alternatives for Liquid and Granular Materials

Liquids and granular materials can often be of high weight and mass. A firm seeks new shipping alternatives to handle both kinds of material. Alternative means of shipping product, inter-plant, between plant and distributor, to the retailer, and ultimately to the consumer are required. Ideally, the new shipping alternatives would result in less packaging, less costly packaging, and greener (more environmental and sustainable) packaging. A possible example is substituting paper packaging for plastic.
