This project emerges form the conviction that design is action.
Tech demo of setup able to levitate, control and maneuver small light objects in a 3D space using ultrasound waves, defying gravity - video embedded below:
The essence of levitation technology is the countervailing of gravity. It is known that an ultrasound standing wave is capable of suspending small particles at its sound pressure nodes and, so far, this method has been used to levitate lightweight particles, small creatures, and water droplets.
The acoustic axis of the ultrasound beam in these previous studies was parallel to the gravitational force, and the levitated objects were manipulated along the fixed axis (i.e. one-dimensionally) by controlling the phases or frequencies of bolted Langevin-type transducers. In the present study, we considered extended acoustic manipulation whereby millimetre-sized particles were levitated and moved three-dimensionally by localised ultrasonic standing waves, which were generated by ultrasonic phased arrays. Our manipulation system has two original features. One is the direction of the ultrasound beam, which is arbitrary because the force acting toward its centre is also utilised. The other is the manipulation principle by which a localised standing wave is generated at an arbitrary position and moved three-dimensionally by opposed and ultrasonic phased arrays. We experimentally confirmed that various materials could be manipulated by our proposed method.
The Distributed Flight Array (DFA) has been developed by a team of researchers at the Institute for Dynamic Systems and Control (IDSC) at ETH Zürich university in Switzerland. Each robot has a 3D-printed hexagonal plastic chassis with magnets fixed to the sides of the frame and a single propeller fitted in the middle. Independently, the honeycomb-shaped robots fly in an erratic and uncontrolled way. However, the robots are able to detect each other, link to form a bigger craft and then fly in a controlled manner as a single unit. The task of keeping the multi-propeller system in flight is distributed across the network of vehicles. Each independent module exchanges information with the others and uses sensors to determine how much thrust it needs for the array to take off and maintain flight.
This fall, MatterPort is releasing a camera that can scan, compile, and make cloud-ready a 3-D model of your house, all in about 45 minutes. “We’re moving towards a world where people can send 3-D realities to each other,” says CEO Matt Bell. The pitch may sound a little New Agey, but with a $3,000 price point and simple iPad interface, the goal is practicality.
Created by Anirudh Sharma, Lirong Liu and Pattie Maes at the MIT Media Lab (Fluid Interfaces Group), Glassified is a modified ruler with a transparent display to supplement physical strokes made on paper with virtual graphics. The goal of the device is to complement rather than replace a typical ruler and since the display is transparent, both the physical strokes and the virtual graphics are visible in the same plane. Digitizer embedded in the ruler captures the pen strokes and updates the graphical overlay, fusing the traditional function of a ruler with the added advantages of a digital, display-based system. The device serves two purposes — to aid the user in drawing straight lines and secondly, it is a tool for taking measurements. Glassified augments both of these functions by means of its transparent, graphical display.
D-printed casts for fractured bones could replace the usual bulky, itchy and smelly plaster or fibreglass ones in this conceptual project by Victoria University of Wellington graduate Jake Evill. The prototype Cortex cast is lightweight, ventilated, washable and thin enough to fit under a shirt sleeve.
The puck-like device is a sleek vital-signs recorder – tracking everything from blood pressure, body temperature and heart rhythm via myriad sensors. The gizmo then beams your vital signs to an app loaded on your phone or tablet, where it’s yours to keep forever. De Brouwer designed the Scanadu Scout to be a DIY doctor’s office, minus the frustration, endless waiting, and lack of empowerment that’s often associated with the health care system.
in fostering an exchange of products and information, ‘hyperlocal market’, an online food exchange platform by london-based designer and 2013 RCA graduate kayleigh thompson encourages the dialogue between buyer and seller, promoting local commerce. the system connects urban growers with fair and professional trade through an interactive website, which works together with a specially designed printer and smartphone application. the program initiates when one becomes a member of the ‘hyperlocal’ community, where users can upload, price and label their products with the app and sell them to a network of registered users.
A prosthetic hand designed for people with missing fingers has been made available to download from the 3D-printing design database Thingiverse (+ movie).
Dubbed Robohand, the prosthesis was conceived by Richard Van As, a South African carpenter who lost four fingers from his right hand in a work accident.
He got in touch with Ivan Owen, a mechanical props designer from the USA, and the pair designed a set of mechanical fingers printed from plastic with a Replicator 2 desktop 3D printer, donated by Makerbot.
"[The Makerbot] dramatically increased the speed at which we could prototype and try out ideas, and gave us the ability to both hold a physical copy of the exact same thing, even though we were separated by 10,000 miles," says Van As in the movie.
They then tried making a complete hand for a child with amniotic band syndrome, a condition that causes babies to be born with missing or severely shortened fingers.
The resulting Robohand is worn around the wrist and lower arm like a gauntlet and driven by the motion of the wrist.
Bending the wrist forwards causes the cabling to pull the fingers closed, while moving it back releases the fingers.
The digits, knuckle block and wrist hinges are all printed by the Makerbot and joined by cabling and stainless steel bolts, all of which are easy to find and replace.
Prototypes of the Robohand in different sizes
"With the Makerbot, as [the child] grows, all we do is scale it up and print him another one, and the hardware just gets taken from that and put on the new hand," explains Van As, adding that old hands can then be reused by other children.
Created at the Mediated Matter Research Group at the MIT Media Lab, The Silk Pavilion explores the relationship between digital and biological fabrication on product and architectural scales. The primary structure was created of 26 polygonal panels made of silk threads laid down by a CNC (Computer-Numerically Controlled) machine, followed by a swarm of 6,500 silkworms spinning flat non-woven silk patches as they locally reinforced the gaps across CNC-deposited silk fibers.
Inspired by the silkworm’s ability to generate a 3D cocoon out of a single multi-property silk thread (1km in length), the overall geometry of the pavilion was created using an algorithm that assigns a single continuous thread across patches providing various degrees of density. Overall density variation was informed by the silkworm itself deployed as a biological “printer” in the creation of a secondary structure.
Affected by spatial and environmental conditions including geometrical density as well as variation in natural light and heat, the silkworms were found to migrate to darker and denser areas. Desired light effects informed variations in material organization across the surface area of the structure. A season-specific sun path diagram mapping solar trajectories in space dictated the location, size and density of apertures within the structure in order to lock-in rays of natural light entering the pavilion from South and East elevations. The central oculus is located against the East elevation and may be used as a sun-clock. Parallel basic research explored the use of silkworms as entities that can “compute” material organization based on external performance criteria. Specifically, we explored the formation of non-woven fiber structures generated by the silkworms as a computational schema for determining shape and material optimization of fiber-based surface structures.
Within few months, if the sculpture was left as is, moths can produce 1.5 million eggs with the potential of constructing up to 250 additional pavilions.

riding tandem on a bicycle is a great joy made difficult by the single-service design of the pedal-driven vehicle. often the weight of an additional passenger creates balance issues, rooted in the a less-than-optimal positioning of the foot pedals. estonian company vigurvant’s ‘tandem extension bicycle pedal’ is a stainless steel device that works in two positions; one as a closed normal pedal and the other open so that the tandem rider can assist in cycling.
in the most recent medical development in artificial organ creation, a team of scientists and physicians from cornell university have engineered 3D printed life-like ears used to treat children born with a congenital deformity called microtia, or help individuals who have lost part or all of their external ear in an accident or from cancer. the artificial body tissue is made by processing additive gels found within living cells - with collagen derived from rat tails and cartilage taken from cow ears.
the modelling process is digitized into an assemble-able human ear, where then high-density gel, similar to the consistency of jell-o is injected into a mold - resulting in flesh resembling that of a human-being. in the future, the engineers will look at new ways to develop populations of human ear cartilage cells from patients instead of cow cartilage, which would reduce any possibility of rejection.
lawrence bonassar, associate professor of biomedical engineering adds: 'it takes half a day to design the mold, a day or so to print it, 30 minutes to inject the gel, and we can remove the ear 15 minutes later. we trim the ear and then let it culture for several days in nourishing cell culture media before it is implanted.’
It uses a slim, low-power sleeve with a couple of electrodes on the back to provide clinical-quality cardiac event readings. You can either hold it in your hands to get a reading of your pulse, or place it on your chest which makes it useful when dealing with a patient who can’t hold it themselves. The sleeve also works wirelessly with the iPhone 4, most likely via Bluetooth, and since it looks like it doesn’t attach to the dock connector I suspect you could get a reading even if you weren’t using it as a sleeve. The iPhonECG will be officially shown at CES next week, and we’ll do our best to hunt it down and get a hands-on. (via Lifetone Technology’s iPhonECG | OhGizmo!)
