Jan. 14, 2008 There is plenty of innovation in micro- and nanotechnologies, but bringing new devices to market is often prohibitively expensive. Many micro devices have small production volumes, while design, packaging and testing are costly. Now European researchers are breaking down the barriers by developing design methodologies that focus on manufacturing, packaging and testing.
In laboratories dotted across the continent, dedicated and ingenious researchers work feverishly for years, or even careers, to increase our understanding of science at the small scale. Along the way, they develop new, innovative devices to detect pressure, acceleration, temperature or direction – and that’s just the beginning.
Researchers now explore tiny devices that eject a dose of medicine at pre-determined intervals. They create entire, micron-sized laboratories or computer systems on a chip. They are discovering just how much room there is at the small scale, as physicist Richard Feynman famously predicted almost 49 years ago.
Ugly, but it works
But innovation at the sharp end lags behind scientific advances. Often the devices only exist in the laboratory as a demonstration. These prototype lab demonstrations look ugly, but often work and they prove functionality at the nano- or micro-scale. They also often determine whether the invention will ever see the light of day.
“For certain types of device, targeting very large volumes in sectors like the automotive and, more recently, the computer gaming industry, there is a promising future,” reveals Patric Salomon, a partner with the PATENT-DfMM network of excellence (NoE). “But for many others, the lab is the only place where these devices are ever really used.”
The reason? Up to 80 percent of the unit cost for micro- and nano-devices is in the packaging and testing phase, and the unit cost must often come in under a euro. “Many innovations are just too expensive to commercialise,” notes Salomon.
But not, perhaps, for much longer. The PATENT-DfMM network was set up to find a way to cut the cost of packaging, testing and manufacturing micro and nano-devices. To do it, the 22-strong consortium had €6.2 million funding from the EU.
“We had a lot of control over how we assessed projects for funding within the network,” says Salomon. “As a result, we were able to get quite a significant impact.” In the end, the NoE supported over 60 small-scale projects.
These looked at ways to simplify the “Design for Micro Manufacture” process. In essence, researchers learn about manufacturing constraints before starting a design and they take these into account during the concept phase, to optimise units for manufacturing processes. This drives down costs and the time to market.
The network funded research into ways of re-using one design, or its building blocks, for a different type of product. It also studied more efficient ways to test for robustness and perform quality control. Already, these projects have had an important impact, though Salomon admits that they are difficult to quantify.
The end of the beginning
But that’s just the beginning. PATENT-DfMM also conceived a series of service clusters, groups of specialists in particular areas of micro- and nanotechnology, offering services in design for manufacture, testing and reliability.
“These target specifically SMEs and can provide help for companies seeking to commercialise a nano- or microtechnology,” notes Salomon. So far, PATENT-DfMM has set up two; one specialised in miniaturised health-monitoring systems (HUMS), while another focuses on reliability (EUMIREL).
In all, it offers hope of a commercial life for the thousands of lost innovations gathering dust in labs across the continent, and more importantly, to make sure future inventions are “designed for manufacture” from their initial development phase.
