Internet of Things” turns out L’Internet des Objets” in French.  So, it’s technically IdO,” not IoT.” But Laurent Massicot, Freescale’s spokesman based in Paris, assured me, Even in France, we also call it IoT.”

But marketing planar transformers has been no easy matter. As is the case with most up-and-coming technologies, planar's development costs are high. For designers and manufacturers alike, it's a technology that makes sense only in high volumes, where development costs can be recouped. In addition, there's market and inventory variation to consider.

Where planars fit in is still an open question. Six months ago, I would have given a different answer to that question,” said Geoff Wildman, senior product manager at Pulse. The switch-mode power supply industry was growing at 12 percent a year ago. Telecom was growing at 35 percent a year ago, but it's flat right now.

The business is cyclical. We'll likely see an overall growth of 5 percent in the power supply market and 10 to 12 percent in telecom supplies by the end of this year.”

For now, the focus is still on custom designs. Our planars go to very specific customers,” said Terry Booker, application and design engineer for Transpower Technologies (Reno, Nev., which sells to power supply manufacturers as well as IC makers that use the transformers in their dc/dc evaluation boards. For the moment, the cost-vs.-volume considerations typical of most custom businesses apply to planars.

New cores and geometries are in continuous development, and virtually all problems appear under control. The largest problem cited is getting a handle on creepage distances and the like in order to meet safety standards.

Thus, the learning curve is evolving. Planar technology-unlike the planar market-is relatively mature; planars are easy to make, for those who know how. The economics driving the custom market aren't a matter of manufacturing difficulty or of users paying a premium for a relatively new technology. Rather, the cost of development and materials is generally higher than for conventional transformers, and the potential user base is undefined.

We're not quite sure where the market is headed,” said David

This 300-watt planar transformer from Transpower Technologies, set next to two conventional 50- and 100-watt units, touts a low profile.

Smolik, director of new product development for magnetics at BI Technologies. There's definitely a demand for planar, but we're not sure there's demand for general planar components as such.

Her words sparked a lively debate at a meeting of technologists from cellular carriers, telecom vendors and other smart-cities specialists.

You are touching on the business model of Facebook and Google [that gather] targeted information about you to do predictive analysis…there are difficulties to overcome here,” said Joachim Schonowski, a project manager in Deutsche Telekom’s T-Labs.

We can’t live in a zero-risk society, but we can live in one that quantifies the risks,” said Birgit de Boissezon who heads a sustainable management group in the European Commission.

Others noted the irony that governments demand systems with rock-solid security, then ask vendors to provide back doors they can use for public safety and surveillance purposes.

Still others said the cat is out of the bag. Smartphones with embedded GPS capabilities along with social networks and smart badges that let us into buildings already have provided intimate details of our comings and goings to anyone savvy enough to read them.
