54 The PCB Design Magazine • May 2017 by Ted Pawela ALTIUM From the early days of printed circuit boards, the electronics industry has made huge strides in board materials, copper printing methods, miniaturization, rigid-flex, ELIC, EDA, and much more. Many of the devices we use in our homes, our vehicles, and in our workplaces would not be possible without this continuous evolution of PCB design and technology. And yet in 2017, we are poised to shift from evo- lution to revolution, driven by the idea of the Internet of Things. By now we've all heard of IoT and have been presented with a multitude of definitions for it. We've also been presented with a set of benefits that sound nice, if not compelling: refrigerators that can tell us when to restock groceries, cars that can avoid traffic, home thermostats and lighting that can be adjusted from our offices, and so much more. But these examples trivial- ize what the IoT will become and the impact it will have on us. When realized, the IoT will transform our world from a collection of in- dependent "things" into an organized system with logic, reasoning, senses, circulation, and motor skills. In other words, all of the devices and systems in our world will become an organ- ism. This might sound scary, and will no doubt evoke visions of dystopian societies where ma- chines rule humans, but that's only because movie scripts need a mechanism called an "in- citing event" upon which to build an exciting story. In real life, this story doesn't need to be scary; in fact, it holds the promise of a world of possibilities to make life safer, healthier, more convenient, and just plain better. Imagine vehicles that can sense a prob- lem before it occurs, and arrange for parts to be put into dealer inventory and service to be performed for you, all without you ever mak- ing a single phone call, and certainly without the roadside breakdown. Picture a farm with the intelligence to sense an increasing pest in- sect population and release pheromones that disrupt mating cycles—reducing the need for chemical pesticides and ultimately making our food supply safer, healthier, and more abun- dant. Imagine biological sensors that detect the leading indicators of health maladies within your body and alert you and your doctor so that ARTICLE
