* Architects print out your new house on a 3D printer and robots build it.
What are they? Houses designed with algorithms, printed out in carbon-fibre form from a three-dimensional printer and built by robots. Advances in computer programming, 3D printing and robotics have opened the door to exciting new architectural forms made from lightweight composite materials such as carbon fibre, fibreglass and Kevlar. The spin-offs include less waste (there are few, if any, off-cuts from a 3D printer), improved energy savings and efficient lightweight structures (using algorithms from natural systems) that can be built where it wasn’t previously feasible (sheer cliffs, floating structures on the ocean).
Who is doing it? Roland Snooks, architect and lecturer at RMIT’s school of architecture and design. Snooks, a Fulbright scholar who spent seven years in the US, is back in Melbourne writing his own computer programs, which he uses to orchestrate futuristic architectural designs. “I think we are on the verge of a revolution in architectural design and construction,” he says. “The relationship between new ways of designing in conjunction with advances in materials and robotic fabrication techniques have the potential to make a radically new architecture.”
Will it work? Yes. A printer that spits out 25-centimetre-cubed objects now costs less than $2000 and the race is on to build the first 3D printed house, which could happen in the next year, says Snooks. With more architects interested in writing computer programs, algorithmic design’s future is bright, even if it’s unlikely to dominate architecture in 20 years. Meanwhile, RMIT has bought two industrial robots (the kind you see on car manufacturing lines) and experiments are underway to adapt them for building construction. What the neighbours may think of the radical designs is another matter.

* Your brain waves can be manipulated to jog memory or scratch bad recollections.
What is it? A brain stimulator to eliminate painful memories or retrieve lost ones. Transcranial magnetic stimulation is used to stimulate nerve cells in areas of the brain that are underactive or overactive, such as in depression and schizophrenia. Dr Jee Hyun Kim says the same technique could be used to manipulate memory. “If you think about sound, it travels through the air on vibrating air particles and they create a wave. It’s the same in the brain,” Kim says. “The neurons are like air particles and they have their own activity that uses electricity. Depending on how different neurons in the same area are activated, the result is an electrical wave in that region of the brain. That wave then transmits to other parts of the brain and, more and more, it seems that memory formation and recollection depends on those waves being synchronous to other regions. I think that, 20 years from now, we could create a device that would enhance synchronous activity of the brain to aid memory recollection or create asynchrony to suppress memories.”
Who’s doing it? Dr Jee Hyun Kim is a researcher with the Florey Institute of Neuroscience and Mental Health in Parkville. Kim is studying memory formation and recall in addiction and anxiety disorders.
Will it work? Kim thinks it will be possible to use magnetic stimulation to jog memories in people with Alzheimer’s disease (as long as the neurons storing the memories are still alive). Weakening memories might be useful for patients with post-traumatic stress disorder. But erasing all recollections of a love gone wrong, as in the film Eternal Sunshine of the Spotless Mind, is a distant prospect. “If we can decode the brainwaves for specific memories then I do think that is possible – but it’s very extreme and a long way off.”

* Farmers can tell exactly what species live on their land by using “sound maps”.
What is it? The solar-powered Automated Biophony Sensor System is, essentially, a high-fidelity listening device. Wireless sensors mounted on trees or poles in, say, an orchard or a grass paddock record animal noises. Encased in an army-green plastic box about half the size of a textbook (it’s waterproof and UV-resistant) the device can collect up to a terabyte of data in a month – that’s thousands of hours of audio. The object of the exercise is to inform farmers about how many different types of animals live on their patch of land. “It’s all about biodiversity and ensuring that whatever you are doing to the land isn’t having a major impact on it,” says Aaron Maher, managing director of Procept. The sensors pick up all environmental noises: both man-made and natural. Certain sounds can be highlighted. “You can delve down further and do species identification with other algorithms as well,” says Maher. The soundscape of pristine forest can be recorded as a baseline for later comparative study. Transmitted wirelessly via the 3G network or by the satellite network, the data is sent to a central server up to a kilometre away.
Who’s doing it? Product development company Procept with the Department of Primary Industries.
Will it work? It already is. A six-month trial in an orchard in Tatura in the Goulburn Valley last June showed that the device was sensitive enough to pick up the sounds of raindrops or a car in the distance. “It’s quite a complex device with a number of technical challenges, not least the Australian environment,” Maher says. “An orchard is nearly the worst-case scenario. It’s got big, thick-foliage trees that are very dense and can get very wet with rain, so that was good to test to make sure that we could still get the wireless data through the network.” The device is yet to provide a full soundscape of a farm with details of the frogs, bats, birds or other creatures that might be living there.

* Catching a peak-hour train is a relatively pleasant experience.
What is it? Overcrowded trains at peak times are a city workers’ bugbear but researchers at Monash are working on a redesign of train carriages that would allow passengers to get on and off faster and improve the flow of people once they’re inside the carriage. Based on the concept of “peak doors”, the new carriages would have two extra doors that operate only in peak times. As well, many of the seats would be folding so that they would be out of the way in the rush hour, making room for more standing passengers. The seats would also be reconfigured so that most run up the middle of the carriage, creating two channels for people to move through the carriage more easily. There would be directions for passengers to move on through the left channel and off through the right.
Who’s doing it? Selby Coxon, deputy head of the faculty of art, design and architecture at Monash University, with colleagues in the engineering faculty.
Would it work? Absolutely. Train carriage design has been fairly static for many years, but these changes are about reorganising what is already in use rather than inventing a new product. The idea relies on manufacturers backing the new concept as well as passengers following the new rules.

* You can listen to music in an ultrasound “bubble” without disturbing anyone around you.
What is it? The sound bubble. At the point where two streams of ultrasound meet, the bubble envelops the listener in a private sound experience – they can listen to music without it being audible to anyone outside their bubble. Using ultrasound, television watchers will be able to hear programs only when they are facing the screen; airports will be able to communicate with individuals exclusively by tracking their smartphones (spelling the death of PA announcements); and people will be able listen to sound in quiet public environments such as libraries without bothering other people.
Who’s doing it? Kyle Slater, engineer and inventor. This is a side project for Slater, who splits his time at the Bionics Institute in East Melbourne between work on the bionic eye project and his PhD on epilepsy research. Born to a musical family, Slater first dabbled at inventing while working at Jaycar Electronics, where he became fascinated with ultrasonic detectors (in sensors that help you park your car). As an electrical engineering and physics undergraduate at the University of Melbourne, he built a device that sent complex sounds (for example, a recorded voice) up to 30 metres away and audible in an area between two and three metres round. His invention, soundBeam, won him an award at a global engineering and technology competition in London in 2010.
Will it work? Well, Slater is convinced but concedes there’s always a risk that it won’t. He hopes to experiment over the next year with audio-visual artist Robin Fox creating sound bubbles using single tones. But it will be a few years before complex audio bubbles are possible, he says. “I know I can create audible sound in a bubble but how good is that audible sound? … If we can make it sound really good then that’s it, it works and it’s not just a novelty science thing – it becomes a reality.” Slater argues that rather than isolating us, sound bubbles could bring us closer together. In public spaces such as airports, a combination of Wi-Fi and mobile phone technology could allow sound bubbles to track and follow individuals, making it feel like the airport is playing our song.

* Thin, flexible solar panels power your camping gear, mobile phone and house.
What is it? Solar panels are big, heavy and made of glass, metal and silicon, right? But it won’t always be that way. A consortium of scientists is working on creating thin, flexible solar cells, which could be printed on sheets of plastic and ultimately incorporated into other materials. The new panels would be cheaper and lighter than the current alternatives. In June the group aims to print thin A4-sized, flexible, plastic solar cells. It will then work on including printed electronics. In what would be “a paradigm shift” for electronics, the combination of flexible electronics and printable solar cells could lead to solar cells incorporated into a range of materials such as roofing sheets and fabrics. Think solar cells in the fabric of shadecloths, clothes and tents. The new technology could also be used to get solar energy to remote and developing communities.
Who’s doing it? A consortium led by Melbourne University (project co-ordinator Dr David Jones) with research partners Monash University and the CSIRO and industry partners including Bluescope Steel, Securency, Innovia Films and Bosch SEA.
Will it work? The team is confident of meeting its June deadline to print A4 sheets of solar panels. With work on flexible electronics progressing fast, solar panels embedded in other materials seem achievable.

* Physios build 3D pictures of their patients’ movements in real time to monitor progress.
What is it? A device slightly larger than a wristwatch, called a portable motion analysis system, which allows physiotherapists to monitor the movements of patients recovering from stroke. Developed over two years at the Parkville base of NICTA (National Information and Communications Technology Australia), the wireless device tracks patient’s limb movements in real time. Physiotherapists can compile a 3D picture. “It gives the physiotherapist better quantitative metrics to know how well the patient is doing in terms of their rehabilitation,” says Dr Jia-Yee, director of health and life sciences in NICTA’s business team. The device, which can be worn on the arms or legs, has the potential to prevent falls by elderly patients and in sport medicine. It could even prevent cricket injuries by looking at the rotation movement of the bowler, says the leader of the biomedical devices and signal processing at NICTA, Dr Tharshan Vaithianathan.
Who’s doing it? NICTA, Royal Melbourne Hospital, Southern Health and the National Ageing Research Institute.
Will it work? It already is. A three-month trial, started in December, involved five Royal Melbourne Hospital stroke patients. “We have been able to monitor how, for example, an injection such as botulinum toxin (Botox) makes them better or worse,” Dr Vaithianathan says.
