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.

Nozzles Provide Spray Pattern Consistency

Macrospray® nozzles produce consistent mists at very low pressure. The nozzles have a uniformly distributed droplet size (10–30 μm Sauter Mean Diameter), which provides greater contact between deodorant, for example, and odorcausing particles or dust. Droplet size can be tuned for the degree of dust particle interaction and “knock-down” required. The nozzles provide multiple tips for high flow.

Uni-Body Composite Plastic Chassis Reduces Part Count

A patented, one-piece, fiber-reinforced plastic composite chassis, produced by sheet molding compression, uses a highglass-content vinyl ester composite structural material, toughened with urethane for fatigue and damage tolerance.

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.

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.
